  Conventionally, a technique for generating an image obtained by deforming a character object in a virtual space is known. According to this technique, the position of the secondary bone in the coordinate system fixed to the main bone is changed, the position of the control point in the coordinate system fixed to the virtual space is calculated based on the amount of change in the position of the secondary bone, The character object in the virtual space is deformed by generating an image in which the shape of the skin is determined based on the calculated position of the control point (see, for example, Patent Document 1).

Japanese Patent No. 4579964

  In the above prior art, it cannot be said that the behavior of the deformed object becomes a natural behavior according to the laws of physics. On the other hand, when the behavior of the deformed object is set to a natural behavior in accordance with the laws of physics, it is necessary to perform a complicated calculation, and there is a problem that the calculation processing load of the information processing apparatus increases.

  The present invention has been made in view of such problems, and image generation capable of making the behavior of a deformed object a natural expression according to a physical law while reducing the processing load of the information processing apparatus. An object is to provide a program and a recording medium on which the image generation program is recorded.

  In order to achieve the above object, an image generation program according to the present invention includes an information processing device that sets a reference point for a deformable deformable object, a reference point setting processing unit that sets a reference point, and one or more A first control point setting processing unit for setting a control point; a first control for executing a first movement process for moving at least one of the control points based on the reference point based on a force acting on the deformable object; It functions as a point movement processing unit.

  By setting a reference point and a control point for the deformed object and moving each control point based on the force acting on the deformed object, the behavior of the deformed object can be expressed in a natural manner according to the laws of physics. . In that case, since the 1st movement process which moves each control point based on a reference | standard point is performed, the calculation at the time of deforming a deformation | transformation object can be simplified, and the calculation processing burden of information processing apparatus can be reduced. As a result, it is possible to make the behavior of the deformed object a natural expression according to the physical law while reducing the processing load on the information processing apparatus.

  Moreover, the moving direction of each control point changes based on the position of the set reference point. Therefore, only by changing the position of the set reference point, the moving direction of each control point can be changed, and the deformation behavior of the deformable object can be changed. Therefore, the deformation behavior of the deformable object can be easily adjusted.

  In the image generation program according to the present invention, preferably, the first control point movement processing unit moves at least one of the control points along a linear direction connecting the control point and the reference point. The first movement process is executed.

  By restricting the movement direction of each control point to the direction along the straight line connecting the control point and the reference point, and moving each control point, the computation when transforming the deformed object can be simplified, and information processing The processing load on the device can be reduced. As a result, high speed and stable control can be realized.

  The image generation program according to the present invention is preferably configured such that the information processing apparatus causes the information processing apparatus to perform the first movement process based on the force and the position of the reference point set by the reference point setting processing unit. It further functions as a first movement amount determination processing unit that determines the movement amount of the control point.

  The amount of movement of each control point changes based on the mode (magnitude, direction) of the force acting on the deformed object and the position of the set reference point. Therefore, by determining the amount of movement of each control point based on the force acting on the deformed object and the position of the set reference point, the deforming behavior of the deformable object can be appropriately expressed.

  The image generation program according to the present invention is preferably configured to cause the information processing apparatus to move the control point in the linear direction in the first movement process based on the force and the position of the reference point. It further functions as a moving direction determination processing unit for determining

  The direction of movement in the moving direction of each control point changes based on the mode (magnitude, direction) of the force acting on the deformed object and the position of the set reference point. Therefore, the deformation behavior of the deformable object can be appropriately expressed by determining the direction of movement in the moving direction of each control point based on the force acting on the deformable object and the position of the set reference point.

  In the image generation program of the present invention, preferably, the movement direction determination processing unit determines a movement direction of a part of the control points among the plurality of control points to one side in the linear direction. The direction of movement of some or all of the remaining control points is determined to be the other side in the linear direction.

  Accordingly, by moving some control points to one side corresponding to the direction of the force acting on the deformed object in the linear direction, the corresponding part of the deformed object is recessed or expanded, and the remaining control points By moving a part or all of this to the other side in the linear direction, it is possible to perform control such that the corresponding part of the deformed object is inflated or dented in the opposite direction.

  For example, when a contact object comes into contact with the deformed object, by moving some control points including the control point corresponding to the contact position of the contact object inward in the linear direction, the corresponding part of the deformed object is moved. It is possible to perform control such that the corresponding part of the deformed object is inflated in the opposite direction by moving the part of the remaining control points to the outside in the linear direction.

  Further, for example, some control points are moved to one side corresponding to the direction of gravity (downward) in the linear direction (for example, when the deformed object is in the downward posture, the control point located on the lower side is included). By moving some control points to the outside in the linear direction, and moving some control points including the control point located on the upper side when the deformed object is in an upward posture) The corresponding part of the deformed object is inflated or recessed (for example, if the deformed object is in the downward posture, the lower part of the deformed object is inflated, and if the deformed object is in the upward posture, the upper part of the deformed object is recessed. Move part or all of the remaining control points to the other side in the linear direction (for example, the deformed object In this case, part or all of the control points located outside the lower side are moved inward in the linear direction. When the deformed object is in the upward orientation, part or all of the control points located outside the upper side are moved to the straight line. The corresponding part of the deformed object is recessed or inflated in the opposite direction (for example, when the deformed object is in a downward posture, one of the parts other than the lower side of the deformed object). It is possible to perform control such as indenting a part or the whole, or inflating a part or all of a portion other than the upper side of the deformed object when the deformed object is in the upward posture.

  Thereby, the deformation | transformation behavior of a deformation | transformation object can be expressed naturally. At this time, it is also possible to deform the deformed object so that the apparent volume becomes substantially constant. In this case, the deformation behavior of the deformed object can be expressed more naturally.

  Further, the image generation program of the present invention is preferably configured such that the information processing apparatus detects a contact of a contact object with respect to the deformed object when the contact is detected by the contact detection processing unit. And further functioning as a first force application processing unit that applies a first force exerted by the contact to at least one control point corresponding to a contact position of the contact object among the plurality of control points, The movement direction determination processing unit applies the first force based on the force including the first force and the position of the reference point when the contact is detected by the contact detection processing unit. The movement direction of the part of the control points including the control point to be determined is determined to the one side, and the movement direction of a part or all of the remaining control points is determined to the other side.

  As a result, when the contact object comes into contact with the deformed object, by moving some control points including the control point corresponding to the contact position of the contact object inward in the linear direction, the corresponding part of the deformed object By moving a part or all of the remaining control points outward in the linear direction, it is possible to perform control such that the corresponding part of the deformed object is swollen in the opposite direction. Thereby, the deformation | transformation behavior of the deformation | transformation object when a contact object contacts can be expressed naturally. At this time, it is also possible to deform the deformed object so that the apparent volume becomes substantially constant. In this case, the deforming behavior of the deformed object when the contact object comes into contact can be expressed more naturally.

  In the image generation program of the present invention, it is preferable that the information processing apparatus sets a first movement amount parameter indicating ease of deformation of a corresponding portion of the deformable object at each of the plurality of control points. The first movement amount determination processing unit further determines a movement amount of the control point based on the first movement amount parameter.

  In general, in the real space, each part of the deformed object differs in ease of deformation depending on, for example, the presence or absence of the covering (exposure), the position, etc. (for example, than the covered part (the part that is not exposed)) The uncoated part (exposed part) is more easily deformed, and the distal end part is more easily deformed than the proximal end part). Therefore, a first movement amount parameter indicating the ease of deformation of the corresponding part of the deformation object is set for each control point, and the movement amount of each control point is determined based on the set first movement amount parameter. Thus, natural softness corresponding to the ease of deformation of each part can be expressed in the deformed object, and the deformation behavior of the deformable object can be expressed naturally.

  In the image generation program of the present invention, preferably, the information processing device causes the gravity to act on the deformed object by applying a downward gravity in a vertical direction to the gravity action processing unit. When the deformable object is in a predetermined reference posture, the first object is further functioned as a second force application processing unit that applies an upward second force in the vertical direction for canceling the deformation due to gravity. The control point movement processing unit executes the first movement process based on the force including the gravity and the second force.

  If the shape of the deformed object placed in the virtual space is designed in the model with the shape of the deformed object with the standard posture and downward gravity acting, if the deformed object is in the standard posture, the deformed object It is desirable not to deform due to the influence of gravity. Therefore, the downward gravity is applied to the deformable object, and when the deformable object is in the reference posture, the upward second force for canceling the deformation due to the gravity is applied, and the gravity and the second force are applied. By executing the first movement process described above based on the force acting on at least a part of the deformed object, the gravity and the second force are balanced when the deformed object is in the reference posture (gravity and Since the resultant force with the second force is 0), the deformed object can be prevented from being deformed by the influence of gravity (the resultant force of gravity and the second force). At this time, it is also possible to change the direction of the second force based on the posture of the deformable object. In this case, when the deformable object is not the reference posture, the gravity and the second force are determined based on the posture of the deformable object. Since the resultant force with the second force changes, the deformable object can be deformed by the influence of gravity (the resultant force of gravity and the second force) so as to have a shape corresponding to the posture. Thereby, a feeling of gravity can be expressed in the deformed object, and the deformation behavior of the deformed object can be naturally expressed.

  In addition, the image generation program of the present invention preferably causes the information processing apparatus to further function as a posture detection processing unit that detects the posture of the deformed object, and the second force action processing unit performs the posture detection processing. The direction of the second force is changed based on the posture of the deformed object detected by the unit.

  As a result, when the deformed object is not in the reference posture, the resultant force of gravity and the second force changes based on the deformed object's posture, so that the deformed object is affected by the gravity (gravity) so as to have a shape corresponding to the posture. And the second force). Thereby, a feeling of gravity can be expressed in the deformed object, and the deformation behavior of the deformed object can be naturally expressed.

  To achieve the above object, an image generation program according to the present invention includes a second control point setting processing unit that sets a plurality of control points for a deformable deformable object supported by a support object. A second control point movement processing unit for executing a second movement process for moving at least one of the plurality of control points based on a force acting on the deformed object; and at least two of the plurality of control points; A second parameter setting processing unit configured to set a second movement amount parameter representing ease of deformation of a corresponding portion of the deformable object so as to change based on a separation distance of the control point from the support object; The second movement amount determination processing unit that determines the movement amount of the control point based on the two movement amount parameters.

  When the movement amount of each control point is determined using the second movement amount parameter relating to the movement amount of the control point, it is not necessary to obtain the movement amount for each control point by a complicated calculation. Can be simplified, and the processing load on the information processing apparatus can be reduced. As a result, high speed and stable control can be realized.

  In general, in the real space, each part of the deformed object has a different ease of deformation based on the distance from the support object (for example, a tip having a larger separation distance than a part on the base end side having a small separation distance). The side part is easier to deform). Therefore, at least two control points are changed based on the separation distance from the support object (for example, the control point on the distal end side having a larger separation distance than the control point on the proximal end side having a small separation distance is deformed). By setting the second movement amount parameter and determining the movement amount of each control point based on the second movement amount parameter set in this way, the tip of the control point on the proximal end side is determined. The deformed object can be deformed so that the movement amount of the control point on the side is larger. Accordingly, natural softness corresponding to the ease of deformation of each part can be expressed in the deformed object, and the deforming behavior of the deformable object can be expressed in a natural manner according to the laws of physics.

  In the image generation program of the present invention, it is preferable that the second parameter setting processing unit has the first control point for the second control point having a larger separation distance than the first control point. The second movement amount parameter is set so as to be more easily deformed.

  In general, in the real space, each part of the deformed object is more easily deformed at the tip side part having a larger separation distance than the base side part having a small distance from the support object. Therefore, by setting the second movement amount parameter so that the tip-side control point having a large separation distance is more easily deformed than the base-side control point having a small separation distance, In addition, the deformable object can be deformed so that the amount of movement of the control point on the tip side is larger. Accordingly, natural softness corresponding to the ease of deformation of each part can be expressed in the deformed object, and the deformation behavior of the deformable object can be naturally expressed.

  The image generation program of the present invention preferably further causes the information processing apparatus to function as a force direction detection processing unit that detects the direction of the force acting on the swingable deformable object, and the second The parameter setting processing unit sets the second movement amount parameter to at least two control points located on the side corresponding to the direction of the force detected by the force direction detection processing unit among the plurality of control points. Set.

  By setting the second movement amount parameter to at least two control points on the swing side so that the control point on the distal end side is more easily deformed than the control point on the proximal end side, the swing side can be set. It is possible to deform the deformed object so that the base end side portion of the lens does not enter the inside of the support object. Thereby, the deformation | transformation behavior of a deformation | transformation object can be expressed more naturally and dynamically.

  The image generation program of the present invention is preferably a game program.

  In order to achieve the above object, a recording medium of the present invention is a recording medium readable by an information processing apparatus on which the image generation program is recorded.

  According to the image generation program and the recording medium of the present invention, it is possible to naturally express the behavior of the deformed object according to the physical law while reducing the processing load of the information processing apparatus.

An example of the outline content will be described.

  As shown in FIGS. 2 and 3, the game according to the present embodiment has one or more characters arranged in a three-dimensional virtual space (or a two-dimensional virtual space) in accordance with the operation of the controller 5 by the player. 51 is to perform various operations. An XYZ coordinate system is set in the three-dimensional virtual space. The character 51 is not particularly limited, and is, for example, a female model, a male model, an animal model other than a human, an object model other than an animal, or the like. Hereinafter, a case where the character 51 is a female model will be described as an example, and hereinafter referred to as “female model 51” as appropriate.

  The predetermined part 53 of the female model 51 can be deformed. The predetermined part 53 is not particularly limited as long as it is soft enough to be deformed. For example, the predetermined part 53 is a breast (breast), a hip, a thigh, an abdomen, a second arm, and the like. Hereinafter, a case where the predetermined portion 53 is the chest will be described as an example, and hereinafter referred to as “chest 53” as appropriate. The chest 53 corresponds to an example of a deformed object, and the body 55 that supports the chest 53 corresponds to an example of a support object. A plurality of control points C for expressing the shape of the chest 53 are set.

  The appearance of the female model 51 is not particularly limited, but is, for example, a swimsuit, an underwear, a uniform, a clothes, or a kimono. Alternatively, the female model 51 may be naked. Hereinafter, a case where the female model 51 is in a swimsuit will be described as an example. That is, the female model 51 wears a swimsuit 59, and at least a part of the surface of the breast 53 is covered with the swimsuit 59. Note that the entire surface of the chest 53 may be exposed.

  The player can operate the controller 5 to cause the female model 51 covered with a swimsuit 59 to cover at least a part of the surface of the chest 53 to perform various operations. At that time, according to the movement of the torso 55 of the female model 51 and the posture change of the chest 53, the gravity and inertia force acting on the chest 53, and the contact of the contact object 57 (see FIG. 6 described later) with the chest 53, By moving at least one of the plurality of control points C set to 53, the chest 53 can be deformed. The “movement” of the control point C here includes “rotation” of the control point C. The contact object 57 is not particularly limited as long as it is an object that can contact the chest 53, but for example, a body model other than the female model 51, a part other than the breast 53 of the female model 51 (for example, the opposite chest 53 ) Etc. When the chest 53 is deformed, at least one of the following first deformation process, second deformation process, and third deformation process is performed.

  Hereinafter, an example of the outline contents of the first deformation process, the second deformation process, and the third deformation process will be sequentially described with reference to FIGS.

  4 to 6, the illustration of the swimsuit 59 is omitted for convenience of explanation. 4 to 6 illustrate only five control points C1 to C5 among the plurality of control points C set on the chest 53. 4 to 6, the shape of the chest 53 before deformation is illustrated by a broken line, and the shape of the chest 53 after deformation is illustrated by a solid line.

(2-1. Outline of First Modification Process)
First, an example of the outline content of the first deformation process will be described with reference to FIG.

  As shown in FIG. 4, in the first deformation process, a force is applied to the chest 53 according to the movement of the body 55 of the female model 51 and the contact of the contact object 57 with the chest 53, and the entire chest 53 is swung ( This is a process for expressing the movement of the entire chest 53 by swinging and vibrating). In the first deformation process, as the movement amount of the swing of the entire chest 53, the movement amount in the vertical and horizontal directions is calculated by a spring model (control that gives an acceleration proportional to the distance toward the target point), and each control point C It is converted into the amount of movement.

  In the example shown in FIG. 4, an upward force (positive in the Y-axis direction) F acts on the chest 53, and each control point C <b> 1 to C <b> 5 moves upward, for example, so that the whole swings upward. 53 behaves to deform.

(2-2. Outline of second deformation process)
Next, an example of the outline content of the second deformation process will be described with reference to FIG.

  As shown in FIG. 5, the second deformation process is a process for expressing the softness that the surface of the chest 53 is generally waved by slightly swinging (vibrating) at each control point C. Also in the second deformation process, as in the first deformation process, the movement amount in the vertical and horizontal directions is calculated by the spring model as the movement amount of the swing of the entire chest 53 and converted into the movement amount of each control point C. . The “swing (vibration)” of the control point C here includes “rotation” of the control point C.

  In the example shown in FIG. 5, the control points C <b> 1 to C <b> 5 move slightly upward (in the positive direction of the Y axis), for example, so that the chest 53 is deformed so that the whole swings slightly upward. .

(2-3. Outline of third deformation process)
Next, an example of the outline content of the third deformation process will be described with reference to FIG.

  As shown in FIG. 6, the third deformation process expresses the depression of the chest 53 and the swelling due to the influence of the contact of the contact object 57 on the chest 53 and the gravity G (see FIG. 10 described later) acting on the chest 53. It is processing of.

  In the example shown in FIG. 6, in response to the contact (collision) of the contact object 57 near the proximal end opposite to the head of the chest 53, the control points C4 and C5 corresponding to the contact position of the contact object 57 are directed upward (Y (Axial positive direction) force F acts, the control points C4 and C5 move inward, and the remaining control points C1 to C3 move outward, so that the contact position of the contact object 57 is recessed, and other parts are The chest 53 is deformed so as to swell.

<3. Functional Configuration Related to Third Modification Process of Information Processing Device>
Next, with reference to FIGS. 7 to 12, an example of a functional configuration mainly related to the third deformation process and the like among the functional configurations of the information processing apparatus 3 will be described. In addition, the arrow shown in FIG. 7 shows an example of the signal flow, and does not limit the signal flow direction.

  8 to 12, as in the case of FIGS. 4 to 6, the illustration of the swimsuit 59 is omitted, and only the control points C <b> 1 to C <b> 5 among the plurality of control points C set on the chest 53 are illustrated and modified. The shape of the front chest 53 is indicated by a broken line, and the shape of the deformed chest 53 is indicated by a solid line.

  As shown in FIG. 7, the information processing device 3 includes a reference point setting processing unit 9, a control point setting processing unit 11 (corresponding to an example of a first control point setting processing unit), and a parameter setting processing unit 13 (first Equivalent to an example of a parameter setting processing unit), a contact detection processing unit 15, a first force action processing unit 17, a gravity action processing unit 19, a posture detection processing unit 21, a second force action processing unit 23, A movement amount determination processing unit 25 (corresponding to an example of a first movement amount determination processing unit), a movement direction determination processing unit 27, a control point movement processing unit 29 (corresponding to an example of a first control point movement processing unit), An image generation processing unit 31 is included.

  The reference point setting processing unit 9 sets at least one (one in this example) reference point B for one breast 53 (see FIG. 8). At this time, the reference point setting processing unit 9 can set the reference point B at an appropriate position with respect to the chest 53. FIG. 8A shows an example in which the reference point B is set at the front side (left side in the figure) of the body 55 with respect to the chest 53. FIG. 8B shows an example in which the reference point B is set to the rear side (right side in the drawing) of the body 55 with respect to the chest 53 from the position shown in FIG. FIG. 8C shows an example in which the reference point B is set at a position lower than the position shown in FIG. 8A of the body 55 relative to the chest 53 (Y-axis direction negative side). Specifically, the position of the reference point B is determined and stored at the time of manufacturing the game, and the reference point setting processing unit 9 reads the stored position of the reference point B to the chest 53. A reference point B is set. Note that the position of the reference point B may be adjustable in accordance with the player's operation on the game setting screen or the like.

  Returning to FIG. 7, the control point setting processing unit 11 sets one or a plurality (in this example, a plurality) of the control points C for one chest 53. For example, the control point setting processing unit 11 sets a plurality of control points C at appropriate positions on the surface of the chest 53 (skin). Specifically, the initial position of each control point C is determined and stored at the time of manufacturing the game, and the control point setting processing unit 11 reads the stored initial position of each control point C, thereby A plurality of control points C are set for 53.

  The parameter setting processing unit 13 sets, for each control point C, a first movement amount parameter that represents the ease of deformation of the corresponding part of the chest 53. Specifically, the first movement amount parameter for each control point C is determined and stored at the time of manufacturing the game, and the parameter setting processing unit 13 sets the first movement amount parameter for each stored control point C. By reading, the first movement amount parameter is set at each control point C. The first movement amount parameter with respect to the control point C is set according to whether or not the corresponding portion of the chest 53 is covered with the swimsuit 59. For example, a portion of the chest 53 that is not covered with the swimsuit 59 is more easily deformed than a portion of the chest 53 that is covered with the swimsuit 59. Therefore, the control point C corresponding to the portion of the chest 53 not covered with the swimsuit 59 is more easily deformed than the control point C corresponding to the portion of the chest 53 covered with the swimsuit 59. A movement amount parameter (for example, a coefficient) is set.

  The contact detection processing unit 15 detects the contact of the contact object 57 with the chest 53. At this time, the contact detection processing unit 15 detects the contact of the contact object 57 with the chest 53 by detecting the contact of the contact object 57 with the control point C. Alternatively, an auxiliary point may be set between two adjacent control points C, and the contact of the contact object with the chest 53 may be detected by detecting the contact of the contact object with the auxiliary point.

  When the contact is detected by the contact detection processing unit 15, the first force action processing unit 17 contacts at least one control point C corresponding to the contact position of the contact object 57 among the plurality of control points C. A force F1 (corresponding to an example of a first force; see FIG. 9 described later) is applied. For example, as shown in FIG. 9, when the contact of the contact object 57 with the control points C4 and C5 located near the base end opposite to the head of the chest 53 is detected, the control points C4 and C5 An upward force (positive in the Y-axis direction) F1 exerted by the contact is applied.

  Returning to FIG. 7, the gravity action processing unit 19 causes the chest 53 to act on the chest 53 in the downward direction (Y-axis direction negative direction) gravity G (see FIG. 10 described later).

  The posture detection processing unit 21 detects the posture of the chest 53. For example, as shown in FIG. 10A, when the head of the female model 51 is positioned above the chest 53 (positive side in the Y-axis direction), the posture of the chest 53 is a forward posture (predetermined reference posture). Is equivalent to an example). Also, for example, as shown in FIG. 10B, when the head of the female model 51 is located on the front side (left side in the figure) with respect to the chest 53, the posture of the chest 53 is detected as a downward posture. .

  Returning to FIG. 7, when the posture of the chest 53 detected by the posture detection processing unit 21 is a forward-facing posture, the second force action processing unit 23 applies the gravity G to the chest 53 on which the gravity action processing unit 19 has acted. , An upward force in the vertical direction (positive in the Y-axis direction) F2 (corresponding to an example of a second force; see FIG. 10) is applied to cancel the deformation due to gravity G, and is detected by the posture detection processing unit 21. When the posture of the chest 53 is a posture other than the forward posture, the direction of the force F2 applied to the chest 53 is changed according to the detected posture. For example, as shown in FIG. 10A, when the posture of the chest 53 is a forward-facing posture and when this is detected, an upward force F <b> 2 is applied to the chest 53. In this case, gravity G and force F2 are balanced (the resultant force becomes 0). Also, for example, as shown in FIG. 10B, when the posture of the chest 53 is a downward posture, and that fact is detected, a forward (leftward in the drawing) force F2 is applied to the chest 53. In this case, gravity G and force F2 are not balanced (the resultant force is not 0).

  Returning to FIG. 7, the control point movement processing unit 29 determines at least one of the plurality of control points C for each control point C and the reference point according to the force acting on at least a part of the chest 53. A first movement process is performed in which movement is performed along a straight line connecting the point B.

  The movement amount determination processing unit 25 includes a force acting on at least a part of the chest 53, that is, a force including gravity G and force F2 (or a force F1 when contact is detected by the contact detection processing unit 15), and The amount of movement of each control point C in the first movement process is determined according to the position of the reference point B set by the reference point setting processing unit 9. At this time, the movement amount determination processing unit 25 determines the movement amount of each control point C based on the first movement amount parameter set to each control point C by the parameter setting processing unit 13.

  The movement direction determination processing unit 27 includes a force that acts on at least a part of the chest 53, that is, a force including gravity G and force F2 (or a force F1 when contact is detected by the contact detection processing unit 15), and The direction of movement in the linear direction of each control point C in the first movement process is determined according to the position of the reference point B set by the reference point setting processing unit 9. At this time, the movement direction determination processing unit 27 determines the movement direction of a part of the control points C among the plurality of control points C to one side in the linear direction, and a part of the remaining control points C or The direction of all movements is determined on the other side in the linear direction. In particular, when contact is detected by the contact detection processing unit 15, the movement direction determination processing unit 27 determines the force F <b> 1 according to the position including the force F <b> 1, gravity G, force F <b> 2, and the reference point B. The direction of movement of a part of the control points C including the control point C on which is applied is determined as one side in the linear direction, and the part or all of the movement directions of the remaining control points C are determined in the linear direction. Decide on the other side.

  Then, the control point movement processing unit 29 executes the first movement process based on the determination results of the movement amount determination processing unit 25 and the movement direction determination processing unit 27.

  For example, in the example shown in FIG. 11A, the reference point B is set at the front side (left side in the figure) of the torso 55 with respect to the chest 53, and the control points C1 to C5 are almost equally deformable. In a state where the first movement amount parameter is set so as to become, the downward gravity G is applied to the chest 53, the posture of the chest 53 is detected as the forward posture, and the upward force F2 is applied to the chest 53. The contact of the contact object 57 with the control points C4 and C5 is detected, and an upward force F1 is applied to the control points C4 and C5. Illustration of gravity G and force F2 is omitted.

  Then, the control points C4 and C5 are moved to the inner side (one side) corresponding to the direction of the force F1 in the linear direction connecting each of the control points C4 and C5 and the reference point B, and the remaining control points C1 to C1 are moved. By moving C3 to the outside (the other side) in the linear direction connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is recessed, and the other part is swollen and the apparent volume. The chest 53 is deformed so that is substantially constant.

  Also, in the example shown in FIG. 11B, the first movement amount parameter is set so that the control point C1 can be more easily deformed than the other control points as in FIG. The difference is that the first movement amount parameter is set so that the deformation is harder than other control points, and the position of the reference point B and the force acting on the chest 53 are the same.

  Also in this case, as in FIG. 11A, the control points C4 and C5 are moved to the inside corresponding to the direction of the force F1 in the linear direction connecting each of the control points C4 and C5 and the reference point B. By moving the remaining control points C1 to C3 to the outside in the linear direction connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is recessed and other parts appear to swell. Although the chest 53 is deformed so that the upper volume is substantially constant, in this example, the portion corresponding to the control point C1 of the chest 53 swells relatively large, and the portion corresponding to the control point C2 is relatively relative. It is small and inflated.

  Further, in the example shown in FIG. 11C, the first movement amount parameter is set so that the control point C1 and the control point C1 are more difficult to be deformed than the other control points, and the control point C2 has the other. The difference is that the first movement amount parameter is set so that the deformation is easier than the control point, and the position of the reference point B and the force acting on the chest 53 are the same.

  Also in this case, as in FIG. 11A, the control points C4 and C5 are moved to the inside corresponding to the direction of the force F1 in the linear direction connecting each of the control points C4 and C5 and the reference point B. By moving the remaining control points C1 to C3 to the outside in the linear direction connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is recessed and other parts appear to swell. Although the chest 53 is deformed so that the upper volume is substantially constant, in this example, the portion corresponding to the control point C1 of the chest 53 swells relatively small, and the portion corresponding to the control point C2 is relative. It is greatly inflated.

  Further, for example, in the example shown in FIG. 12A, the reference point B is set at the front side (lower side in the figure) of the body 55 with respect to the chest 53, and the control points C1 to C5 are easily deformed. In a state where the first movement amount parameter is set so as to be approximately the same, and the contact of the contact object with the chest 53 is not detected, the downward gravity G is applied to the chest 53, and the posture of the chest 53 is the downward posture. It is detected that there is a force F2 acting forward (leftward in the figure) on the chest 53.

  Then, the control points C1, C3, C5 are moved to the outside (one side) in the linear direction connecting the control points C1, C3, C5 and the reference point B, and the remaining control points C2, C4 are moved to the control points. By moving the inner side (the other side) in the linear direction connecting C2, C4 and the reference point B, the chest 53 is deformed so that the distal end side extends. At this time, chest 53 is. The tip side is deformed so that it slightly faces the head side.

  Also, the example shown in FIG. 12 (b) differs from FIG. 12 (a) above in that the reference point B is set at the rear side (upper side in the figure) of the body 55 with respect to the chest 53. The one movement amount parameter and the force acting on the chest 53 are the same.

  In this case, by moving the control points C1 to C5 to the outside in the linear direction connecting the control points C1 to C5 and the reference point B, the chest 53 is deformed so that the whole swells.

  Also, the example shown in FIG. 12C is different from FIG. 12A in that the reference point B is set at a position opposite to the chest 53 from the head of the body 55 (right side in the figure). The first movement amount parameter and the force acting on the chest 53 are the same.

  In this case, the control points C1, C4, and C5 are moved to the outside (one side) in the linear direction connecting the control points C1, C4, and C5 and the reference point B, and control is performed among the remaining control points C2 and C3. By moving the point C2 to the inside (the other side) in the linear direction connecting the control point C2 and the reference point B, the chest 53 is deformed so as to swell on the opposite side to the head.

  Returning to FIG. 7, the image generation processing unit 31 generates an image of the female model 51 including the image of the breast 53 after the first movement process. The image of the female model 51 is combined with another image (an image of another object model, a background image, or the like), output to the display device 7, and displayed on the display device 7.

  Note that the processing in each processing unit described above is not limited to the example of sharing of these processing, and may be processed by, for example, a smaller number of processing units (for example, one processing unit), Further, it may be processed by a further subdivided processing unit. The functions of each processing unit described above are implemented by a game program executed by a CPU 101 (see FIG. 17 described later), for example, a part of which is a dedicated integrated circuit such as an ASIC or FPGA, and the like. It may be implemented by an actual device such as an electric circuit.

A first movement process is performed in which movement is performed along a linear direction connecting the point C and the reference point B.

  In step S120, the information processing apparatus 3 causes the image generation processing unit 31 to generate an image of the female model 51 including the image of the breast 53 after the first movement process in step S110.

  In step S130, the information processing apparatus 3 combines the image of the female model 51 generated in step S120 with another image (an image of another object model, a background image, etc.), and outputs it to the display device 7, Display.

  In step S140, the information processing apparatus 3 determines whether a predetermined end command has been input. If the end command has not been input (step S140: NO), the process returns to step S40 and the same procedure is repeated. If an end command has been input (step S140: YES), this flow ends.

  In addition, the process procedure mentioned above is an example, Comprising: At least one part of the said procedure may be deleted or changed, and procedures other than the above may be added. Moreover, you may change the order of at least one part of the said procedure.

<5. Functional Configuration Related to First Modification Process of Information Processing Device>
Next, with reference to FIGS. 14 and 15, an example of a functional configuration mainly related to the first deformation process and the like among the functional configurations of the information processing apparatus 3 will be described. In addition, the arrow shown in FIG. 14 shows an example of the signal flow, and does not limit the signal flow direction.

  In FIG. 15, similarly to FIGS. 4 to 6, the illustration of the swimsuit 59 is omitted, and only the control points C <b> 1 to C <b> 5 among the plurality of control points C set on the chest 53 are illustrated.

  The control point setting processing unit 33 sets a plurality of control points C for one chest 53. For example, the control point setting processing unit 33 sets a plurality of control points C at appropriate positions on the surface of the chest 53 (skin). Specifically, the initial position of each control point C is determined and stored at the time of manufacturing the game, and the control point setting processing unit 33 reads the stored initial position of each control point C, thereby A plurality of control points C are set for 53.

  The force application processing unit 34 applies a force F3 (see FIG. 15 described later) to at least a part of the chest 53 in accordance with the movement of the body 55 and the contact of the contact object 57 with the chest 53.

The second movement amount parameter (e.g., magnification) is set so that it is easier to deform than the control point C on the tip side. For example, when the direction of the detected force F3 is upward (when swinging upward), the second movement amount parameter is set to at least two control points C located on the upper side, and the detected force F3 is detected. If the direction is downward (when swinging downward), the second movement amount parameter is set to at least two control points C located on the lower side.

At this time, the second movement amount parameter is set so that the control point C3 is easier to deform than the control point C2, and the control point C1 is more easily deformed than the control point C3. Then, by moving the control points C1 to C5 upward, the chest 53 is deformed so that the entire tip is swung upward while the tip end is swung more than the base end.

  In the example shown in FIG. 15B, the direction of the force F3 acting on the chest 53 is detected to be downward, and the second movement amount parameter is set at the control points C1, C4, and C5. At this time, the second movement amount parameter is set so that the control point C5 is easier to deform than the control point C4, and the control point C1 is easier to deform than the control point C5. Then, by moving the control points C1 to C5 downward, the chest 53 is deformed so that the entire distal end side swings more greatly than the proximal end side while swinging downward.

  In addition, the game program may be recorded temporarily or permanently on, for example, a magnetic disk such as a flexible disk, various CDs, MO disks, optical disks such as a DVD, or a removable recording medium 125 such as a semiconductor memory. it can. Such a recording medium 125 can also be provided as so-called package software. In this case, the game program recorded in these recording media 125 may be read by the drive 119 and recorded in the recording device 117 via the input / output interface 111, the bus 109, or the like.

  In addition, the game program can be recorded on, for example, a download site, another computer, another recording device, or the like (not shown).

<8. Effects of the embodiment>
As described above, the game program of this embodiment causes the information processing apparatus 3 to function as the reference point setting processing unit 9, the control point setting processing unit 11, and the control point movement processing unit 13. The reference point setting processing unit 9 sets a reference point B for the chest 53. The control point setting processing unit 11 sets a plurality of control points C for the chest 53. The control point movement processing unit 13 executes a first movement process that moves at least one of the plurality of control points C based on the reference point B based on the force acting on the chest 53.

  By setting a reference point B and a control point C for the chest 53 and moving each control point C based on the force acting on the chest 53, the behavior of the chest 53 is made a natural expression according to the physical law. be able to. At this time, since the first movement process for moving each control point C based on the reference point B is executed, the calculation when the chest 53 is deformed can be simplified, and the calculation processing load of the information processing apparatus 3 can be reduced. As a result, it is possible to make the behavior of the chest 53 a natural expression according to the physical law while reducing the processing load on the information processing apparatus 3.

  Further, the moving direction of each control point C changes based on the position of the reference point B that is set. Therefore, the movement direction of each control point C can be changed and the deformation behavior of the chest 53 can be changed simply by changing the position of the reference point B to be set. Therefore, the deformation behavior of the chest 53 can be easily adjusted.

  In the present embodiment, in particular, the control point movement processing unit 29 performs a first movement process in which at least one of the plurality of control points C is moved along a linear direction connecting the control point C and the reference point B. Run.

  The movement direction of each control point C is limited to the direction along the linear direction connecting the control point C and the reference point B, and each control point C is moved, thereby simplifying the calculation when the chest 53 is deformed. The calculation processing load of the information processing apparatus 3 can be reduced. As a result, high speed and stable control can be realized.

  In the present embodiment, in particular, the information processing apparatus 3 is further caused to function as the movement amount determination processing unit 25. Based on the force acting on at least a part of the chest 53 and the position of the reference point B set by the reference point setting processing unit 9, the movement amount determination processing unit 25 determines the control point B in the first movement process. Determine the amount of movement.

  The amount of movement of each control point B changes based on the mode (size, direction) of the force acting on the chest 53 and the position of the reference point B that is set. Therefore, by determining the amount of movement of each control point C based on the force acting on the chest 53 and the set position of the reference point B, the deformation behavior of the chest 53 can be appropriately expressed.

  In the present embodiment, in particular, the information processing apparatus 3 further functions as the movement direction determination processing unit 27. Based on the force acting on at least a part of the chest 53 and the position of the reference point B set by the reference point setting processing unit 9, the movement direction determination processing unit 27 sets the control point C in the first movement process. The direction of movement in the linear direction is determined.

  The direction of movement in the moving direction of each control point C changes based on the mode (magnitude, direction) of the force acting on the chest 53 and the position of the reference point B that is set. Therefore, by determining the direction of movement in the movement direction of each control point C based on the force acting on the chest 53 and the position of the set reference point B, the deformation behavior of the chest 53 can be appropriately expressed. .

  In the present embodiment, in particular, the movement direction determination processing unit 27 determines the movement direction of some control points C among the plurality of control points C to one side in the linear direction, and the remaining control points. The direction of movement of a part or all of C is determined on the other side in the linear direction.

  Accordingly, by moving some control points C to one side corresponding to the direction of the force acting on the chest 53 in the linear direction, the corresponding portion of the chest 53 is recessed or inflated, and the remaining control is performed. By moving a part or all of the point C to the other side in the linear direction, it is possible to perform control such that the corresponding part of the chest 53 is inflated or recessed opposite to the above.

  For example, when the contact object 57 comes into contact with the chest 53, a part of the control points C including the control point C corresponding to the contact position of the contact object 57 is moved inward in the linear direction, so that the chest 53 It is possible to perform control such that the corresponding part is indented and the corresponding part of the chest 53 is inflated in the opposite direction by moving part or all of the remaining control points C outward in the linear direction. It becomes possible.

  Further, for example, a part of the control points C is moved to one side corresponding to the direction of gravity (downward) in the linear direction (for example, when the chest 53 is in the downward posture, the control point C positioned on the lower side). When the chest 53 is in the upward posture, some control points C including the control point C located on the upper side are moved inward in the linear direction. The corresponding portion of the chest 53 is inflated or recessed (for example, when the chest 53 is in the downward posture, the lower portion of the chest 53 is inflated, and when the chest 53 is in the upward posture, the chest 53 ), And part or all of the remaining control point C is moved to the other side in the linear direction (for example, when the chest 53 is in the downward posture, the control point C positioned other than the lower side). Place some or all of them in the linear direction When the chest 53 is in the upward posture, a part or all of the control point C located on the side other than the upper side is moved outward in the linear direction), so that the corresponding part of the chest 53 is Concave or bulge in the opposite direction (for example, when the chest 53 is in the downward posture, part or all of the portion other than the lower side of the chest 53 is recessed, and when the chest 53 is in the upward posture, the upper side of the chest 53 It is possible to perform control such as inflating part or all of the other parts.

  Thereby, the deformation behavior of the chest 53 can be naturally expressed. At this time, it is also possible to deform the chest 53 so that the apparent volume becomes substantially constant. In this case, the deformation behavior of the chest 53 can be expressed more naturally.

  In the present embodiment, in particular, the information processing device 3 is further caused to function as the contact detection processing unit 15 and the first force action processing unit 17. The contact detection processing unit 15 detects contact of the contact object 57 with the chest 53. When the contact is detected by the contact detection processing unit 15, the first force action processing unit 17 applies the above-described control point C to at least one control point C corresponding to the contact position of the contact object 57. A force F1 exerted by the contact is applied. The movement direction determination processing unit 27 is set by the reference point setting processing unit 9 and the force acting on at least a part of the chest 53 including the force F1 when the contact detection processing unit 15 detects the contact. Based on the position of the reference point B, the movement direction of a part of the control points C including the control point C to which the force F1 acts is determined to the one side, and the movement of a part or all of the remaining control points C is determined. The direction is determined on the other side.

  Thereby, when the contact object 57 comes into contact with the chest 53, the chest 53 is moved by moving some control points C including the control point C corresponding to the contact position of the contact object 57 inward in the linear direction. And performing control such that the corresponding part of the chest 53 is inflated in the opposite direction by moving part or all of the remaining control points C outward in the linear direction. Is possible. Thereby, the deformation | transformation behavior of the chest 53 when the contact object 57 contacts can be expressed naturally. At this time, it is also possible to deform the chest 53 so that the apparent volume becomes substantially constant. In this case, the deformation behavior of the chest 53 when the contact object 57 contacts can be expressed more naturally. .

  In the present embodiment, in particular, the information processing apparatus 3 further functions as the parameter setting processing unit 13. The parameter setting processing unit 13 sets, for each of the plurality of control points C, a first movement amount parameter that represents the ease of deformation of the corresponding part of the chest 53. The movement amount determination processing unit 25 determines the movement amount of the control point C based on the first movement amount parameter.

  In general, in the real space, each part of the chest 53 differs in ease of deformation based on, for example, the presence or absence of the covering (exposed), the position, etc. (for example, more than the covered part (non-exposed part)). The uncoated part (exposed part) is more easily deformed, and the distal end part is more easily deformed than the proximal end part). Therefore, a first movement amount parameter indicating the ease of deformation of the corresponding part of the chest 53 is set at each control point C, and the movement amount of each control point C is set based on the set first movement amount parameter. By determining, natural softness corresponding to the ease of deformation of each part can be expressed on the chest 53, and the deformation behavior of the chest 53 can be expressed naturally.

  In the present embodiment, in particular, the information processing apparatus 3 is further caused to function as the gravity action processing unit 19 and the second force action processing unit 23. The gravity action processing unit 19 causes the downward gravity G in the vertical direction to act on the chest 53. The second force application processing unit 23 applies an upward force F2 in the vertical direction for canceling deformation due to the gravity G when the chest 53 to which the gravity G is applied by the gravity action processing unit 19 is in a forward posture. . The 29 control point movement processing unit executes the first movement process based on the force acting on at least a part of the chest 53 including the gravity G and the force F2.

  When the shape of the chest 53 arranged in the virtual space is designed with the shape of the chest 53 in a state in which the posture of the chest 53 is in a forward posture and the downward gravity G is acting on the model, It is desirable not to deform 53 under the influence of gravity G. Accordingly, the downward gravity G is applied to the chest 53, and when the chest 53 is in the forward posture, the upward force F2 for canceling the deformation due to the gravity G is applied, and the gravity G and the force F2 are included. By executing the first movement process described above based on the force acting on at least a part of the chest 53, when the chest 53 is in the forward posture, the gravity G and the force F2 are balanced (gravity G and force Therefore, the chest 53 can be prevented from being deformed by the influence of the gravity G (the resultant force of the gravity G and the force F2). At this time, it is also possible to change the direction of the force F2 based on the posture of the chest 53. In this case, when the chest 53 is not in a forward posture, the gravity G and the force F2 are based on the posture of the chest 53. Therefore, the chest 53 can be deformed by the influence of the gravity G (the resultant force of the gravity G and the force F2) so as to have a shape corresponding to the posture. Thereby, a feeling of gravity can be expressed on the chest 53, and the deformation behavior of the chest 53 can be expressed naturally.

  In the present embodiment, in particular, the information processing apparatus 3 further functions as the posture detection processing unit 21. The posture detection processing unit 21 detects the posture of the chest 53. The second force action processing unit 23 changes the direction of the force F <b> 2 based on the posture of the chest 53 detected by the posture detection processing unit 21.

  As a result, when the chest 53 is not in the forward posture, the resultant force of the gravity G and the force F2 changes based on the posture of the chest 53. Therefore, the chest 53 is affected by the gravity G (gravity) so as to have a shape corresponding to the posture. (The resultant force of G and force F2). Thereby, a feeling of gravity can be expressed on the chest 53, and the deformation behavior of the chest 53 can be expressed naturally.

  In addition, the game program of the present embodiment causes the information processing apparatus 3 to function as the control point setting processing unit 33, the control point movement processing unit 43, the parameter setting processing unit 37, and the movement amount determination processing unit 39. The control point setting processing unit 33 sets a plurality of control points C for the chest 53 supported by the trunk 55. The control point movement processing unit 43 executes a second movement process for moving at least one of the plurality of control points C based on the force acting on the chest 53. The parameter setting processing unit 37 sets the second movement amount parameter indicating the ease of deformation of the corresponding part of the chest 53 to at least two of the plurality of control points C, and separates the control point C from the support object body 55. Set to change based on distance. The movement amount determination processing unit 39 determines the movement amount of the control point C based on the second movement amount parameter.

  By determining the movement amount of each control point C using the second movement amount parameter relating to the movement amount of the control point C, it is not necessary to calculate the movement amount for each control point C by a complicated calculation. The calculation at the time of the deformation can be simplified, and the calculation processing load of the information processing apparatus 3 can be reduced. As a result, high speed and stable control can be realized.

  In general, in the real space, each part of the chest 53 differs in ease of deformation based on the separation distance from the body 55 (for example, a distal end having a larger separation distance than a proximal end part having a small separation distance). The side part is easier to deform). Accordingly, at least two control points C are changed based on the separation distance from the body 55 (for example, the control point C on the distal end side having a larger separation distance than the control point C on the proximal end side having a small separation distance). The second movement amount parameter is set (so that the deformation becomes easier), and the movement amount of each control point C is determined based on the second movement amount parameter set in this way, thereby controlling the proximal end side. The chest 53 can be deformed so that the amount of movement is greater at the control point C on the distal end side than at the point C. As a result, natural softness corresponding to the ease of deformation of each part can be expressed on the chest 53, and the deformation behavior of the chest 53 can be expressed naturally according to the laws of physics.

  Further, in the present embodiment, the parameter setting processing unit 37 is more deformed than the control point C on the proximal end side with respect to the control point C on the distal end side, which has a larger separation distance than the control point C on the proximal end side. The second movement amount parameter is set so as to be easy.

  In general, in the real space, each part of the chest 53 is more likely to be deformed at a distal end portion having a larger separation distance than a proximal end portion having a smaller separation distance from the body 55. Therefore, by setting the second movement amount parameter so that the distal-side control point C having a larger separation distance is more easily deformed than the proximal-side control point C having a smaller separation distance, the proximal-side control is performed. The chest 53 can be deformed so that the amount of movement is greater at the control point C on the tip side than at the point C. Accordingly, natural softness corresponding to the ease of deformation of each part can be expressed on the chest 53, and the deformation behavior of the chest 53 can be expressed naturally.

  In the present embodiment, in particular, the information processing device 3 further functions as the force direction detection processing unit 35. The force direction detection processing unit 35 detects the direction of the force F3 acting on the swingable chest 53. The parameter setting processing unit 37 sets the second movement amount parameter to at least two control points C located on the side corresponding to the direction of the force F3 detected by the force direction detection processing unit 35 among the plurality of control points C. Set.

  By setting the second movement amount parameter to at least two control points C on the swing side so that the control point C on the distal end side is more easily deformed than the control point C on the proximal end side, The chest 53 can be deformed so that the base end portion of the moving side does not enter the body 55. Thereby, the deformation behavior of the chest 53 can be expressed more naturally and dynamically.
