Conventionally, there is known a technique of generating an image in which a character object in a virtual space is deformed. According to this technique, the position of the sub bone in the coordinate system fixed to the main bone is changed, and the position of the control point in the coordinate system fixed in the virtual space is calculated based on the change amount of the position of the sub 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 (for example, refer to Patent Document 1).

Patent No. 4579964

In the above conventional technique, it cannot be said that the behavior of the deformed object is a natural behavior according to the physical law. On the other hand, when the behavior of the deformable object is to be a natural behavior according to the physical law, it is necessary to perform a complicated calculation, which causes a problem that the calculation processing load of the information processing device increases.

The present invention has been made in view of such a problem, and it is possible to reduce the calculation processing load of the information processing apparatus and generate an image that enables the behavior of the deformable object to be a natural expression according to a physical law. An object of the present invention is to provide a program and a recording medium on which the image generation program is recorded.

In order to achieve the above-mentioned object, an image generation program of the present invention includes an information processing apparatus, a reference point setting processing unit that sets a reference point for a deformable deformable object, and one or more reference points for the deformable object. A first control point setting processing unit that sets a control point, a first control that executes a first movement process that moves 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 reference points and control points for the deformable object and moving each control point based on the force acting on the deformable object, the behavior of the deformable object can be expressed naturally according to the physical law. .. At that time, since the first moving process of moving each control point based on the reference point is executed, the calculation at the time of deforming the deformable object can be simplified, and the calculation processing load of the information processing device can be reduced. As a result, it is possible to reduce the calculation processing load of the information processing apparatus and to make the behavior of the deformable object a natural expression in accordance with the physical law.

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 reference point to be set, it is possible to change the moving direction of each control point and change the deformation behavior of the deformable object. Therefore, the deformation behavior of the deformable object can be easily adjusted.

Further, in the image generation program of 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 moving 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 calculation at the time of deforming the deformable object can be simplified, and the information processing can be performed. The calculation processing load of the device can be reduced. As a result, high speed and stable control can be realized.

Further, the image generation program of the present invention is preferably configured such that the information processing device is configured to perform the information processing device in 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 (size, direction) of the force acting on the deformable object and the position of the reference point that is set. Therefore, the deformation behavior of the deformable object can be appropriately expressed by determining the amount of movement of each control point based on the force acting on the deformable object and the position of the set reference point.

Further, the image generation program of the present invention preferably causes the information processing device to move in the linear direction of the control point 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 that determines.

The direction of movement of each control point in the movement direction changes based on the mode (magnitude, direction) of the force acting on the deformable object and the position of the reference point that is set. 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.

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

Thereby, by moving some control points to one side corresponding to the direction of the force acting on the deformable object in the straight line direction, the corresponding portion of the deformable object is recessed or inflated, and the remaining control points. By moving a part or all of the above to the other side in the straight line direction, it is possible to perform control such that the corresponding part of the deformable object is inflated or recessed opposite to the above.

For example, when the contact object touches the deformed object, some control points including the control points corresponding to the contact position of the contact object are moved inward in the linear direction to move the corresponding portion of the deformed object. By denting and moving some or all of the remaining control points to the outside in the straight line direction, it is possible to perform control such that the corresponding portion of the deformable object is inflated in the opposite manner to the above.

In addition, for example, some control points are moved to one side corresponding to the direction of gravity (downward) in the above-mentioned linear direction (for example, when the deformed object is in the downward posture, the control points located on the lower side are included. By moving some control points to the outside in the straight line direction, when the deformed object is in the upward posture, move some control points including the control points located on the upper side to the inside in the straight line direction), Inflate or dent the corresponding part of the deformable object (for example, inflate the lower part of the deformable object when the deformable object is in the downward attitude, and indent the upper part of the deformable object when the deformable object is in the upward attitude). No), move some or all of the remaining control points to the other side in the above-mentioned straight line direction (for example, if the deformed object is in the downward posture, move some or all of the control points other than below to the above straight line). By moving inward in the direction, or moving some or all of the control points other than the upper side in the upward direction when the deformable object is in the upward posture), the corresponding portion of the deformable object is On the contrary, it dents or swells (for example, when the deformable object is in the downward posture, part or all of the portion other than the lower side of the deformable object is indented, and when the deformable object is in the upward posture, It is possible to perform control such as inflating a part or all of the portion other than the upper side).

As a result, the deformation behavior of the deformable object can be naturally expressed. Further, at this time, the deformable object can be deformed so that the apparent volume becomes substantially constant, and in this case, the deforming behavior of the deformable object can be expressed more naturally.

Further, the image generation program of the present invention, preferably, the information processing device, when the contact is detected by the contact detection processing unit that detects the contact of the contact object with the deformed object, the contact detection processing unit, Of the plurality of control points, at least one of the control points corresponding to the contact position of the contact object is further caused to function as a first force action processing section that applies a first force exerted by the contact, and 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 direction of movement of the part of the control points including the control point is determined to be the one side, and the direction of movement of part or all of the remaining control points is determined to the other side.

As a result, when the contact object touches the deformed object, some control points including the control points corresponding to the contact position of the contact object are moved inward in the straight line direction so that the corresponding portion of the deformed object is moved. By denting and moving some or all of the remaining control points to the outside in the straight line direction, it is possible to perform control such that the corresponding portion of the deformable object is inflated in the opposite direction. Thereby, the deformation behavior of the deformable object when the contact object contacts can be naturally expressed. Further, at this time, it is possible to deform the deformable object so that the apparent volume becomes substantially constant, and in this case, the deforming behavior of the deformable object when the contact object makes contact can be expressed more naturally.

In the image generation program of the present invention, preferably, the information processing apparatus sets, for each of the plurality of control points, a first movement amount parameter indicating easiness of deformation of a corresponding portion of the deformation object. The first movement amount determination processing unit determines the movement amount of the control point based on the first movement amount parameter.

Generally, in the physical space, each part of the deformed object is different in easiness of deformation depending on, for example, the presence or absence of the covering (exposing), the position, and the like (for example, compared to the covered part (unexposed part) The uncoated portion (exposed portion) is more likely to be deformed, and the distal end portion is more likely to be deformed than the proximal end portion). Therefore, the first movement amount parameter indicating the easiness of deformation of the corresponding portion of the deformation object is set to each control point, and the movement amount of each control point is determined based on the set first movement amount parameter. As a result, the softness of the deformable object can be naturally expressed according to the easiness of deformation of each part, and the deformation behavior of the deformable object can be naturally expressed.

Further, preferably, the image generation program of the present invention causes the information processing device to cause the deformed object to exert gravity by a gravity action processing unit that exerts downward gravity in a vertical direction, and the gravity action processing unit. When the deformed object has a predetermined reference posture, it further functions as a second force action processing unit that exerts an upward second force in the vertical direction for canceling the deformation due to the gravity. The control point movement processing unit executes the first movement processing based on the force including the gravity and the second force.

When the shape of the deformable object placed in the virtual space is the reference posture and the shape of the deformable object in the state where downward gravity is applied is designed as a model, when the deformable object has the reference posture, the deformable object is 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 above-described first movement process based on the force acting on at least a part of the deformable 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), it is possible to prevent the deformed object from being deformed due to the influence of gravity (the resultant force between 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 in the reference posture, gravity and the first force are changed based on the posture of the deformable object. Since the resultant force of 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 deformable 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 device to further function as a posture detection processing unit that detects the posture of the deformed object, and the second force action processing unit may perform 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 the gravity and the second force changes based on the posture of the deformed object, so that the deformed object is affected by the gravity (gravity And the second force). Thereby, a feeling of gravity can be expressed in the deformable object, and the deforming behavior of the deformable object can be naturally expressed.

In order to achieve the above object, the image generation program of the present invention causes an information processing apparatus to set a second control point setting processing unit that sets a plurality of control points for a deformable deformable object supported by a supporting object, A second control point movement processing unit that executes a second movement process that moves at least one of the plurality of control points based on a force acting on the deformable object; and at least two of the plurality of control points, A second parameter setting processing unit that sets a second movement amount parameter that indicates the ease of deformation of the corresponding portion of the deformable object so as to change based on the distance between the control point and the supporting object. A second movement amount determination processing unit that determines the movement amount of the control point based on the second movement amount parameter.

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

In general, in real space, each part of the deformable object is different in ease of deformation based on the distance from the supporting object (for example, the tip having a larger separation distance than the base end part having a small separation distance). The side part is easier to deform). Therefore, at least two control points are changed so as to change based on the separation distance from the supporting object (for example, the control point on the tip side having a larger separation distance is deformed than the control point on the base end side having a smaller separation distance). By setting the second movement amount parameter and determining the movement amount of each control point on the basis of the second movement amount parameter set in this way, the tip of the control point on the proximal side is set. It is possible to deform the deformable object so that the control point on the side has a larger movement amount. As a result, the deformed object can be expressed as a natural softness according to the easiness of deformation of each part, and the deformation behavior of the deformed object can be expressed naturally according to the physical law.

Further, in the image generation program of the present invention, preferably, the second parameter setting processing unit sets the first control point to the second control point whose separation distance is larger than that of the first control point. The second movement amount parameter is set so that the second movement amount parameter is more easily deformed.

Generally, in the real space, each part of the deformable object is more likely to be deformed at the tip side part having a larger separation distance than the base end part having a smaller separation distance from the support object. Therefore, the second movement amount parameter is set so that the control point on the distal end side having a larger separation distance is more easily deformed than the control point on the base end side having a smaller separation distance. Also, the deformable object can be deformed such that the control point on the tip end side has a larger movement amount. As a result, it is possible to express the natural softness of the deformable object according to the ease of deformation of each part, and to naturally express the deforming behavior of the deformable object.

The image generation program of the present invention preferably further causes the information processing device to further function as a force direction detection processing unit that detects the direction of the force acting on the swingable deformable object. 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 so that the control point on the distal end side is more easily deformed than the control point on the proximal end side, at least two control points on the swinging side are set. It is possible to deform the deformable object so that the base end side part of does not enter the inside of the supporting object. Thereby, the deformation behavior of the deformable 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 in which the image generation program is recorded and which can be read by an information processing device.

According to the image generation program and the recording medium of the present invention, it is possible to naturally express the behavior of a deformable object in accordance with a physical law while reducing the calculation processing load of the information processing device.

An example of the outline content of will be described.

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

The predetermined part 53 of the female model 51 is deformable. The predetermined portion 53 is not particularly limited as long as it is a soft portion that can be deformed, but is, for example, the chest (breast), hips, thighs, abdomen, or upper arms. Hereinafter, the case where the predetermined portion 53 is the chest will be described as an example, and will be appropriately referred to as a “chest 53”. 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.

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 chest 53 is covered with the swimsuit 59. The entire surface of the chest 53 may be exposed.

The player can operate the controller 5 to cause the female model 51 whose part including at least a part of the surface of the chest 53 is covered with the swimsuit 59 to perform various actions. At that time, in response to the movement of the body 55 of the female model 51 or the posture change of the chest 53, gravity or inertial force acting on the chest 53, or contact of the contact object 57 (see FIG. 6 described later) on the chest 53, the chest is moved. The chest 53 can be deformed by moving at least one of the plurality of control points C set to 53. The "movement" of the control point C here also includes the "rotation" of the control point C. The contact object 57 is not particularly limited as long as it is an object capable of contacting the chest 53. For example, an object model other than the female model 51, a site other than the chest 53 of the female model 51 (for example, the chest 53 on the opposite side). ) Etc. When deforming the chest 53, at least one of the following first deformation processing, second deformation processing, and third deformation processing is performed.

(2-1. Outline of first transformation process)
First, an example of the outline content of the first transformation 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 in accordance with the movement of the body 55 of the female model 51 or 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 or vibrating. In the first deformation process, the amount of movement in the vertical and horizontal directions as the amount of movement of the entire chest 53 is calculated by a spring model (control that gives acceleration proportional to the distance toward the target point), and each control point C Is converted to the movement amount of.

In the example shown in FIG. 4, an upward (Y-axis direction positive) force F acts on the chest 53, and the control points C1 to C5 move upward, for example, so that the entire chest swings upward. The behavior of 53 is deformed.

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

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

In the example shown in FIG. 5, each of the control points C1 to C5 slightly moves upward (positive in the Y-axis direction), so that the chest 53 deforms so that the entire body swings slightly upward. ..

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

As shown in FIG. 6, the third transformation process represents the contact of the contact object 57 with the chest 53 and the dent or bulge of the chest 53 due to the effect of gravity G acting on the chest 53 (see FIG. 10 described later). Processing.

In the example shown in FIG. 6, the control points C4 and C5 corresponding to the contact position of the contact object 57 are moved upward (Y The force F (in the positive axial direction) acts, the control points C4 and C5 move inward, and the remaining control points C1 to C3 move outward, whereby the contact position of the contact object 57 is dented and other parts are The chest 53 behaves as if it were inflated.

<3. Functional configuration related to third transformation processing of information processing device>
Next, with reference to FIGS. 7 to 12, an example of the functional configuration mainly related to the third modification processing and the like among the functional configurations of the information processing device 3 will be described. The arrows shown in FIG. 7 indicate an example of signal flow, and do not limit the signal flow direction.

Similar to FIGS. 4 to 6, in FIGS. 8 to 12, the swimsuit 59 is omitted and only the control points C1 to C5 among the plurality of control points C set on the chest 53 are illustrated and modified. The shape of the front chest 53 is shown by a broken line, and the shape of the chest 53 after deformation is shown by a solid line.

As illustrated 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 (Corresponding 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), The 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 chest 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 a position on the front side (left side in the drawing) 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 chest 53 at a position on the rear side (right side in the drawing) of the body 55 relative to the position shown in FIG. 8A. FIG. 8C is an example in which the reference point B is set at a position lower than the position of the body 55 with respect to the chest 53 shown in FIG. 8A (negative side in the Y-axis direction). 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 out the stored position of the reference point B to the chest 53. The reference point B is set. Note that the position of the reference point B may be adjustable according to the operation of the player on the game setting screen or the like.

Returning to FIG. 7, the control point setting processing unit 11 sets one or a plurality (a plurality in this example) 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 (skin) of the chest 53. 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, 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 indicating the easiness of deformation of the corresponding portion of the chest 53. Specifically, the first movement amount parameter for each control point C is determined and stored when the game is manufactured, and the parameter setting processing unit 13 sets the stored first movement amount parameter for each 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, the portion of the chest 53 not covered with the swimsuit 59 is more easily deformed than the portion of the chest 53 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 likely to be 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 control point C, thereby detecting the contact of the contact object 57 with the chest 53. The contact of the contact object with the chest 53 may be detected by setting an auxiliary point between two adjacent control points C and 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 applies the contact to 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 the first force, which will be described later, see FIG. 9) exerted by 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 on the side opposite to the head of the chest 53 is detected, the control points C4 and C5 are An upward (Y-axis direction positive direction) force F1 exerted by the contact is applied.

Returning to FIG. 7, the gravity action processing unit 19 causes the chest 53 to exert downward gravity (negative Y-axis direction) gravity G in the vertical direction (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 located above the chest 53 (on the Y axis direction positive side), the posture of the chest 53 is a forward posture (a predetermined reference posture). (Corresponding to one example). Further, 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 to be the downward posture. ..

Returning to FIG. 7, when the posture of the chest 53 detected by the posture detection processing unit 21 is a forward posture, the second force action processing unit 23 causes the gravity action processing unit 19 to apply gravity G to the chest 53. , The posture detection processing unit 21 detects an upward force (positive direction in the Y-axis direction) F2 in the vertical direction (which corresponds to an example of the second force; see FIG. 10) for canceling the deformation due to the gravity G. When the posture of the chest 53 is a posture other than the forward posture, the direction of the force F2 acting on 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 the forward posture and the fact is detected, the upward force F2 is applied to the chest 53. In this case, the gravity G and the force F2 are balanced (the resultant force becomes 0). Further, for example, as shown in FIG. 10B, when the chest 53 is in the downward posture and that fact is detected, a forward (leftward in the figure) force F2 is applied to the chest 53. In this case, the gravity G and the force F2 are not balanced (the resultant force does not become zero).

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

The movement amount determination processing unit 25 exerts a force acting on at least a part of the chest 53, that is, a force including gravity G and force F2 (further 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 at each control point C by the parameter setting processing unit 13.

The movement direction determination processing unit 27 includes a force acting on at least a part of the chest 53, that is, a force including gravity G and force F2 (further force F1 when contact is detected by the contact detection processing unit 15), and The direction of movement of each control point C in the first movement process in the linear direction 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 to be the other side in the linear direction. Particularly, when the contact is detected by the contact detection processing unit 15, the movement direction determination processing unit 27 determines the force F1 according to the force F1, the gravity G, the force including the force F2, and the position of the reference point B. Determines the movement direction of a part of the control points C including the control point C acting on one side in the straight line direction, and the movement direction of part or all of the remaining control points C in the straight line 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 a position on the front side (left side in the figure) of the body 55 with respect to the chest 53, and the control points C1 to C5 are substantially the same in ease of deformation. With the first movement amount parameter set so that, the downward gravity G is applied to the chest 53, and it is detected that the posture of the chest 53 is 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 the upward force F1 is applied to the control points C4 and C5. The illustration of the gravity G and the force F2 is omitted.

Then, the control points C4 and C5 are moved to the inside (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. By moving C3 to the outside (the other side) in the direction of the straight line connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is dented and the other parts swell and the apparent volume is increased. The chest 53 is deformed so that is substantially constant.

In the example shown in FIG. 11B, the first movement amount parameter is set to the control point C1 so that the control point C1 is more easily deformed than the other control points, and the control point C2 is set to the control point C2. The point that the first movement amount parameter is set so that it is more difficult to deform 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 the case of FIG. 11A, the control points C4 and C5 are moved to the inner 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. By moving the remaining control points C1 to C3 to the outside in the straight line direction connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is dented and other parts 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 and the portion corresponding to the control point C2 relatively moves. It is inflated to a small size.

Further, in the example shown in FIG. 11C, the first movement amount parameter is set in FIG. 11A and the control point C1 so that the control point C1 is less likely to be deformed than other control points, and the control point C2 is set to the other one. The point where the first movement amount parameter is set so as to be more easily deformed than the control point is, 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 the case of FIG. 11A, the control points C4 and C5 are moved to the inner side corresponding to the direction of the force F1 in the straight line 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 straight line direction connecting each of the control points C1 to C3 and the reference point B, the contact position of the contact object 57 is dented and other parts are swollen. 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 relatively moves. It is greatly inflated.

Further, for example, in the example shown in FIG. 12A, the reference point B is set at a position on 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 deformable. The first movement amount parameter is set to be approximately the same, and when 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 chest 53 is in the downward posture. It is detected that the chest 53 is applied with a forward force F2 (leftward in the figure).

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. The chest 53 is deformed so that the distal end side extends by moving it inward (in the other side) in the direction of the straight line connecting C2 and C4 and the reference point B. At this time, the chest 53. The tip side is deformed so that it is slightly facing the head side.

The example shown in FIG. 12B is different from the example shown in FIG. 12A in that the reference point B is set at a position on the rear side (upper side in the figure) of the body 55 with respect to the chest 53. The 1-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 direction of the straight line connecting the control points C1 to C5 and the reference point B, the chest 53 is deformed so that the whole is inflated.

In addition, the example shown in FIG. 12C is different from the above-mentioned FIG. 12A in that the reference point B is set at a position opposite to the head of the body 55 with respect to the chest 53 (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, C5 are moved to the outer side (one side) in the straight line connecting the control points C1, C4, C5 and the reference point B, and the remaining control points C2, C3 are controlled. By moving the point C2 to the inner side (the other side) in the straight line connecting the control point C2 and the reference point B, the chest 53 is deformed so as to bulge toward the side opposite 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 chest 53 after the first movement processing. 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 by the display device 7.

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

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

Note that the processing procedure described above is an example, and at least a part of the procedure may be deleted or changed, or a procedure other than the above may be added. Further, the order of at least part of the above procedure may be changed.

The processing unit 43 (corresponding to an example of a second control point movement processing unit) and the image generation processing unit 45 are included.

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 (skin) of the chest 53. 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, 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 response to 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 the control point C is more likely to be deformed 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 set. When the direction of is downward (when swinging downward), the second movement amount parameter is set to at least two control points C located on the lower side.

Then, the control point movement processing unit 43 executes the second movement process based on the determination results of the movement amount determination processing unit 39 and the movement direction determination processing unit 41.

For example, in the example shown in FIG. 15A, the direction of the force F3 acting on the chest 53 is detected to be upward, and the second movement amount parameter is set to the control points C1 to C3. At this time, the second movement amount parameter is set so that the control point C3 is more easily deformed 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 body swings upward and the distal end side swings more than the proximal end side.

Further, 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, C5. At this time, the second movement amount parameter is set so that the control point C5 is more easily deformed than the control point C4 and the control point C1 is more easily deformed than the control point C5. Then, by moving the control points C1 to C5 downward, the chest 53 is deformed such that the entire body swings downward and the distal end side swings more than the proximal end side.

Returning to FIG. 14, the image generation processing unit 45 generates an image of the female model 51 including the image of the chest 53 after the second movement processing. 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 by the display device 7.

Note that the processing in each processing unit described above is not limited to an example of sharing of these processings, and may be processed by a smaller number of processing units (for example, one processing unit), In addition, it may be processed by a further subdivided processing unit. The functions of the respective processing units described above are implemented by a game program executed by a CPU 101 (see FIG. 17 described later) described later.

<8. Effect of Embodiment>
As described above, the game program of the present embodiment causes the information processing device 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 the reference point B for the chest 53. The control point setting processing unit 11 sets a plurality of control points C on the chest 53. The control point movement processing unit 13 executes a first movement process of moving 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 on 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 that time, since the first moving process of moving each control point C based on the reference point B is executed, the calculation when deforming the chest 53 can be simplified, and the calculation processing load of the information processing device 3 can be reduced. As a result, the behavior of the chest 53 can be expressed naturally according to the physical laws while reducing the calculation processing load of the information processing device 3.

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

Further, particularly in the present embodiment, the control point movement processing unit 29 performs the first movement process of moving at least one of the plurality of control points C along the straight line direction connecting the control point C and the reference point B. Execute.

By restricting the moving direction of each control point C to the direction along the straight line connecting the control point C and the reference point B and moving each control point C, the calculation when deforming the chest 53 is simplified. Therefore, the calculation processing load of the information processing device 3 can be reduced. As a result, high speed and stable control can be realized.

Further, particularly in the present embodiment, the information processing device 3 further functions as the movement amount determination processing unit 25. The movement amount determination processing unit 25 determines the control point B in the first movement process 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. Determine the amount of movement.

The amount of movement of each control point B changes based on the mode (size, orientation) of the force acting on the chest 53 and the position of the reference point B that is set. Therefore, by determining the moving amount 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.

Further, particularly in the present embodiment, the information processing device 3 further functions as the movement direction determination processing unit 27. The movement direction determination processing unit 27 determines the control point C in the first movement process 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 direction of movement in the linear direction is determined.

The direction of movement of each control point C in the moving direction 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 movement direction of each control point C in the movement direction 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. ..

Further, particularly in the present embodiment, the moving direction determination processing unit 27 determines the moving direction of some of the 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 part or all of C is determined to be 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 straight line 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, some of the control points C including the control point C corresponding to the contact position of the contact object 57 are moved inward in the linear direction, so that the chest 53 It is possible to perform control such that the corresponding portion of the chest 53 is inflated in the opposite direction by denting the corresponding portion and moving some or all of the remaining control points C outward in the linear direction. It will be possible.

Further, for example, some of the control points C are moved to one side corresponding to the direction of gravity (downward) in the linear direction (for example, when the chest 53 is in a downward posture, the control points C located on the lower side). A part of the control points C including the control points C including the control points C located on the upper side when the chest 53 is in the upward posture. To inflate or dent the corresponding portion of the chest 53 (eg, inflate the lower portion of the chest 53 when the chest 53 is in the downward position, or the chest 53 when the chest 53 is in the upward position). The upper part of the control point C), and a part or all of the remaining control points C are moved to the other side in the straight line direction (for example, when the chest 53 is in the downward posture, the control points C located other than the lower side are controlled). By moving some or all of the control points C inward in the straight line direction, or moving all or part of the control points C located other than the upper side in the upward posture when the chest 53 is in the upward posture), The corresponding portion of 53 is recessed or inflated in the opposite manner to the above (for example, when the chest 53 is in the downward position, part or all of the portion other than the lower side of the chest 53 is recessed, the chest 53 is directed upward). In the case of the posture, it is possible to perform a control such as inflating a part or all of the portion other than the upper side of the chest 53).

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

Further, particularly in the present embodiment, the information processing device 3 further functions as the contact detection processing unit 15 and the first force action processing unit 17. The contact detection processing unit 15 detects the 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 sets the above-mentioned at least one control point C corresponding to the contact position of the contact object 57 among the plurality of control points C as described above. 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 is detected by the contact detection processing unit 15. Based on the position of the reference point B, the direction of movement of a part of the control points C including the control point C on which the force F1 acts is determined to the one side, and a part or all of the remaining control points C are moved. The orientation is determined to the other side.

Accordingly, when the contact object 57 contacts 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 to the inner side in the linear direction, whereby the chest 53 is moved. The corresponding portion of the chest 53 is inflated in the opposite direction to the above by moving a part or all of the remaining control points C outward in the linear direction. Is possible. Thereby, the deformation behavior of the chest 53 when the contact object 57 contacts can be naturally expressed. At this time, it is also possible to deform the chest 53 so that the apparent volume becomes substantially constant, and in this case, the deformation behavior of the chest 53 when the contact object 57 contacts can be expressed more naturally. ..

Further, particularly in the present embodiment, the information processing device 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 indicating the easiness of deformation of the corresponding portion 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.

Generally, in the real space, each part of the chest 53 is different in easiness of deformation based on, for example, the presence or absence of the covering (exposed), the position, etc. The uncoated portion (exposed portion) is more likely to be deformed, and the distal end portion is more likely to be deformed than the proximal end portion). Therefore, the first movement amount parameter indicating the easiness of deformation of the corresponding portion of the chest 53 is set to 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, the natural softness according to the easiness of deformation of each part can be expressed on the chest 53, and the deformation behavior of the chest 53 can be naturally expressed.

Further, particularly in the present embodiment, the information processing device 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 applies downward gravity G in the vertical direction to the chest 53. The second force action processing unit 23 exerts an upward force F2 in the vertical direction for canceling the 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 the forward posture. .. The 29 control point movement processing unit executes the first movement processing 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 placed in the virtual space is a forward posture and the shape of the chest 53 in a state in which the downward gravity G acts is designed as a model, when the chest 53 is in the forward posture, It is desirable not to deform 53 under the influence of gravity G. Therefore, the downward gravity G is applied to the chest 53, and the upward force F2 for canceling the deformation due to the gravity G is applied when the chest 53 is in the forward posture, and the gravity G and the force F2 are included. When the chest 53 is in the forward posture, the gravity G and the force F2 are balanced (the gravity G and the force are balanced) by executing the above-described first movement process based on the force acting on at least a part of the chest 53. Since the resultant force with F2 is 0), the chest 53 can be prevented from being deformed by the influence of the gravity G (the resultant force between the gravity G and the force F2). At this time, the direction of the force F2 can be changed based on the posture of the chest 53. In this case, when the chest 53 is not in the forward posture, the gravity G and the force F2 are determined based on the posture of the chest 53. Since the resultant force changes with, 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 naturally expressed.

Further, particularly in the present embodiment, the information processing device 3 is caused to further function 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 F2 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 facing posture, the resultant force of the gravity G and the force F2 changes based on the posture of the chest 53, so that the chest 53 is influenced by the gravity G (gravity It can be deformed by the combined force of G and the force F2. Thereby, a feeling of gravity can be expressed on the chest 53, and the deformation behavior of the chest 53 can be naturally expressed.

Further, the game program of the present embodiment causes the information processing device 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 on the chest 53 supported by the body 55. The control point movement processing unit 43 executes the second movement processing of 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, for at least two of the plurality of control points C, a second movement amount parameter indicating the easiness of deformation of the corresponding portion of the chest 53, and the control point C is separated from the supporting 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, so that the chest 53 is The calculation when deforming can be simplified, and the calculation processing load of the information processing device 3 can be reduced. As a result, high speed and stable control can be realized.

Generally, in the real space, each part of the chest 53 has different easiness of deformation based on the distance from the body 55 (for example, the distal end having a larger distance than the base end side having a smaller distance). The side part is easier to deform). Therefore, at least two control points C are changed so as to change 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 smaller separation distance). By setting the second movement amount parameter so that the control point C can be deformed more easily, and determining the movement amount of each control point C based on the second movement amount parameter set in this way, the control on the base end side is performed. It is possible to deform the chest 53 so that the control point C on the tip side of the point C has a larger movement amount. As a result, natural softness can be expressed on the chest 53 according to the easiness of deformation of each part, and the deformation behavior of the chest 53 can be expressed naturally according to the physical law.

Further, particularly in the present embodiment, the parameter setting processing unit 37 deforms 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, from the control point C on the proximal end side. The second movement amount parameter is set so as to be easy.

Generally, 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 at a proximal end portion having a smaller separation distance from the body 55. Therefore, by setting the second movement amount parameter so that the control point C on the distal end side having a larger separation distance is more easily deformed than the control point C on the base end side having a smaller separation distance, the control on the base end side is performed. The chest 53 can be deformed so that the control point C closer to the tip end than the point C has a larger movement amount. As a result, natural softness can be expressed on the chest 53 according to the ease of deformation of each part, and the deformation behavior of the chest 53 can be naturally expressed.

Further, particularly in the present embodiment, 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 so that at least two control points C on the swinging side are more easily deformed at the control point C on the distal end side than at the control point C on the proximal end side, It is possible to deform the chest 53 so that the base end side portion on the moving side does not enter the inside of the body 55. As a result, the deformation behavior of the chest 53 can be expressed more naturally and dynamically.
