Description

  The present invention relates to an image generation system and an information storage medium.

  2. Description of the Related Art Conventionally, an image generation system that generates an image that can be seen from a given viewpoint in an object space that is a virtual three-dimensional space is known, and is popular as being able to experience so-called virtual reality. Taking an image generation system that can enjoy a gun game as an example, a player (operator) uses a gun-type controller (shooting device) imitating a gun or the like to display enemy characters (screened on the screen). Enjoy 3D games by shooting target objects such as objects.

  In such an image generation system, it is an important technical problem to generate a more realistic image in order to improve the player's virtual reality. Therefore, it is desirable to be able to express more realistically what pulverizes when an impact such as a bullet is applied, such as glass.

  However, in the conventional image generation system, when a bullet hits the glass, it has only been replaced with an image of a crushed glass plate prepared in advance. Even hit anywhere for this, also receives the different bullets of power, only the image of the glass plate was ground in the same manner are displayed, has been a image representation lacked reality monotonic.

Also, according to this method, if you hit the first shot and crush it, the shape will not change no matter how many shots you hit after that, for example, there is a possibility of hitting many shots continuously due to high-speed continuous fire The image representation of was insufficient.

  The present invention has been made in view of such conventional problems, and an object thereof is an image generation system capable of generating an image in which a state change occurs in an object according to an impact position in real time with a smaller amount of data and a calculation load. And providing an information storage medium.

  The present invention is an image generation system for generating an image of a collective object configured by a collection of a plurality of part objects. When an impact is applied to the collective object, the image generation system exists within a predetermined range including an impact position. An image by changing at least one of a shape, a color, a position, a rotation, a direction, a moving direction, and a speed of a part object that is determined as a change target, and a change target determination unit that determines the display mode of the part object. And means for performing generation.

  The information storage medium according to the present invention is an information storage medium that can be used by a computer, and includes information (program) for realizing (executing) the means. A program according to the present invention is a program that can be used by a computer, and includes a processing routine for realizing (executing) the above means.

  The predetermined range including the impact position may be within a certain distance from the impact position, for example, or may be a predetermined range above or below the impact position. How to set the predetermined range may be determined according to the contents of the aggregate object to be expressed or the contents of how to collapse due to impact.

  According to the present invention, it is possible to generate an image in which at least one of the shape, color, position, rotation, direction, moving direction, and speed of a part object within a given range including the applied impact position is changed. Therefore, an image in which the object changes according to the impact position can be expressed more realistically.

  The image generation system, information storage medium, and program according to the present invention determine a range in which the display mode of the part object is changed based on at least one of the magnitude of impact, the direction of impact, and the type of aggregate object. It is characterized by.

  By doing so, it is possible to represent an image of an object that changes reflecting the magnitude of the impact, the direction of the impact, the type of the aggregate object, and the like. For example, the larger the impact, the larger the range to be changed.

  The image generation system, the information storage medium, and the program according to the present invention include means for randomly determining a range in which the display mode of the part object is changed.

  The shape and size of the range for changing the display mode may be calculated in real time, or may be selected from a plurality of candidates prepared in advance. In this way, it is possible to prevent changes due to impact from becoming monotonous.

  The image generation system, the information storage medium, and the program according to the present invention include means for changing the display mode by delaying a part object that is farther from the impact position.

  According to the present invention, it is possible to generate an image in which the periphery of the impact position is changed in a chain manner with a time lag.

  The image generation system, the information storage medium, and the program according to the present invention include means for changing a part object that has changed to the first display mode to the second display mode with the passage of a given time. And

  According to the present invention, it is possible to generate an image when the state changes without fail after a certain period of time has elapsed.

  For example, when tableware dropped from a shelf collides with the floor and breaks, the time until the moment it falls from the shelf and collides with the floor is obtained by calculation. In such a case, according to the present invention, when a predetermined time elapses after changing to the first state of falling, it can be changed to the second state of colliding with the floor and breaking.

  An image generation system, an information storage medium, and a program according to the present invention have a plurality of change image patterns for generating an image of a part object after a change caused by an impact, and are selected from the plurality of change image patterns. An image of the part object after the change due to the impact is generated based on the given change image pattern.

  The selection may be performed randomly or according to a predetermined relationship.

  By preparing a plurality of change image patterns in this way, a more complicated change state can be created.

  For example, by making it possible to select from a plurality of change image patterns representing pulverized states, it is possible to prevent the expression from becoming monotonous and to perform pulverized expression rich in reality.

  An image generation system, an information storage medium, and a program according to the present invention are characterized in that a collective object is configured by combining plural shape part objects without gaps.

  For example, a collective object such as a glass plate or a wall can be expressed by combining a plurality of shape part objects without gaps to form a single plane.

  By combining multiple shape part objects, it is possible to prevent monotonous breakage when displaying a collective object broken by an impact.

  Further, if the contour of each part object has a complicated shape with many irregularities, it may be possible to express a jaggedness when it is broken.

  The image generation system, information storage medium, and program according to the present invention may be configured as a single object before the impact is applied to the collective object to generate an image, and after the impact is applied, a plurality of part objects are generated. It is characterized in that the image generation is performed by constructing as a collective object.

  According to the present invention, before the impact is applied, the image generation is performed by configuring as a single object, so that the processing load at the time of image generation can be reduced. As described above, it is possible to efficiently generate an image by properly using a single object and a collective object as necessary.

2. Features and operations of the present embodiment The features and operations of the present embodiment will be described by taking a case where a glass plate is crushed by bullets as an example.

  3 and 4 are examples of game images of the present embodiment. 3 in FIG. 3 shows a state before pulverization of glass to be crushed by bullets in this embodiment. Reference numeral 300 in FIG. 4 represents a state of the glass 300 that is crushed around the position where the bullet is received in the vicinity of 310.

  As described above, in this embodiment, the predetermined range 320 including the hit position 310 is crushed. Even hit anywhere because this differs from the conventional game image to be pulverized in the same way, it is possible to generate a game image rich reality milling to reflect the hit position.

  An example of processing for generating an image as shown in FIGS. 3 and 4 in this embodiment will be described.

  FIGS. 5A and 5B are diagrams for explaining a configuration example of an object of a glass plate to be crushed by a bullet impact according to the present embodiment.

  In this embodiment, as shown in FIG. 5A, one glass plate 400 is disassembled into parts objects of fine glass pieces as shown by 410, 420, and 430. A single glass surface is expressed by combining these part objects without gaps.

  It is preferable to configure the glass plate as a single object before receiving an impact and to divide it into part objects after receiving the impact. This is because it is possible to reduce the calculation load and to efficiently generate an image by generating an image as a single object before receiving an impact.

  FIG. 5B is a diagram for explaining the types of part objects of glass pieces. In the present embodiment, the glass plate 400 that is a collective object is configured using part objects of glass pieces having three different shapes such as 410, 420, and 430. Each glass piece part object 410, 420, 430 is composed of a plurality of polygonal surfaces. For example, the glass piece part object 410 is composed of polygon planes 410-1, 410-2, 410-3, 410-4, and 410-5.

  The reason why a plurality of different types of glass pieces are used in combination is to prevent the breaking method and the broken shape from becoming monotonous.

  6A and 6B are diagrams for explaining the impact position and the pulverization range. If a bullet hits 450 in FIG. 6A, the glass piece of the part object existing in the predetermined range 460 including the hit position becomes the display mode change target.

  Then, the part object of the glass piece to be changed is changed to a change image pattern (hereinafter referred to as “crush pattern”) representing the crushed state.

  FIG. 7 is a diagram for explaining a pulverization pattern of a part object of each glass piece. In this embodiment, when a bullet hits, the display mode of the part objects of the plurality of glass pieces that are the change target changes to a pulverization pattern. For example, the glass piece 410 changes to a 412 grinding pattern, the glass piece 420 changes to a 422 grinding pattern, and the glass piece 430 changes to a 432 grinding pattern.

  The pulverized pattern is displayed at a position where the crushed pattern is further dropped as the frame advances.

  FIG. 8 is a diagram for explaining the transition of an image when one glass piece is crushed.

  Reference numeral 710 denotes an image of a part object of a glass piece before crushing, and an image of a glass piece in a normal state is displayed at a predetermined position. For example, each glass piece in FIG. 5A corresponds to a case where an image of a glass piece in a normal state is displayed at a predetermined position.

  720 to 740 in FIG. 8 represent an image of a glass piece having a pulverization pattern. As the time has elapsed since the pulverization, 720, 730, and 740 are crushed to a position closer to the ground as the fall proceeds. A pattern image is displayed. In this state, the place where the glass piece originally existed is removed from the glass plate as indicated by reference numeral 470 in FIG. 6B, and an image of the glass plate with a hole is generated.

  Further, instead of breaking all at once, the glass pieces of the part object that are far from the impact position may be delayed so as to collapse.

  FIGS. 9A, 9B, 9C, and 9D are diagrams for explaining a configuration in which the glass piece of the part object that is farther from the impact position is delayed and collapsed.

  Assuming that 480 in FIG. 9A is an impact position, immediately after the impact, the glass piece 490 of the part object in the primary change range (within L1) that is the closest range from the impact position 480 is first crushed. FIG. 9B shows a state in which a hole 492 is formed in the crushed glass piece.

  Next, the glass pieces of the part object in the secondary change range (within L2) 500, which is the second closest range from the impact position 480, are crushed with a delay of several frames. FIG. 9C shows a state in which a hole 502 is formed in the crushed glass piece.

  Next, the glass piece of the part object in the three-event change range (within L3) 510 that is the third closest range from the impact position 480 is crushed with a delay of several frames. FIG. 9D shows a state in which a hole 512 is formed in the crushed glass piece.

  The part objects belonging to each change range may be obtained based on the distance from the impact position. Based on the position coordinates of each part object, the distance GLn to each glass piece is calculated. If GLn <L1, it is pulverized at the first timing, and if L1 <GLn <L2, it is pulverized at the next timing, and L2 <GLn < If it is L3, it is pulverized at the next timing. By doing so, it is possible to generate an image in which the collapse starts to spread around the impact position and the collapse spreads.

  The size and shape of the pulverization range may be determined in real time depending on the magnitude of the impact, the direction of the impact, the type of the aggregate object, and the like. Further, it may be determined depending on the magnitude of the impact, the direction of the impact, the type of the collective object, or the like, whether it collapses at the time of pulverization or gradually disintegrates.

  10A, 10B, and 10C are diagrams for explaining another example of pulverization. For example, if a bullet hits the vicinity of 510 in FIG. 10A, first, the part object of the glass piece at the position of 510 is removed, and an image of the corresponding pulverization pattern is generated. Thereafter, after several frames, the glass piece part objects 512 to 524 located above 510 are removed (see FIG. 10B), and an image of the corresponding pulverization pattern is generated. Further, a few frames later, the glass piece part objects located above the removed glass piece part objects 512 to 524 are removed (see FIG. 10C), and an image of the corresponding crushed pattern is generated. The

  As described above, when a bullet hits, the glass piece near the hit position may be broken first, and then the upper glass piece may be broken sequentially by delaying several frames.

  11 to 13 are flowcharts for explaining an operation example of the present embodiment. In the present embodiment, the following processing is performed for each frame to generate images of the glass plate before and after crushing.

  In the present embodiment, a hit flag is provided to indicate the current state of an object that may be disassembled into a part object due to an impact, such as a glass plate. And it is “0” when not hit yet, “1” immediately after the hit, “2” when the processing immediately after the hit is over and delay processing is performed, and “3” when all changes due to the hit are finished. It is comprised so that it may become.

  When a bullet hits anywhere on the glass plate, '1' is set in the hit flag (steps S10 and S20). In this case, the hit flag changes from '0' to '1' for the first hit, and the hit flag changes from '3' to '1' for the second and subsequent hits.

  If the hit flag is '0', image generation is performed with the glass plate as a single object (steps S30 and S40). In this case, since the glass has not been crushed anywhere, the processing load is lighter if image generation is performed with a single object.

  If the hit flag is other than “0”, image generation is performed with the glass plate as a set object that is a set of part objects of a plurality of glass pieces (steps S30 and S50).

  FIG. 12 is a flowchart for explaining a more detailed processing example of the aggregate object image generation processing in step S50 of FIG.

  First, it is determined whether or not the current state is that all changes due to hits have been completed, that is, whether or not the hit flag is '3' (step S110). If the hit flag is '3', the display mode of each part object is the same as that of the previous frame, and there is no new part object to be changed. Therefore, the processing of the processing group steps S120 to S170 for detecting a new change target is omitted.

  If the hit flag is not 3, it is determined whether the current frame is a frame immediately after the hit, that is, whether the hit flag is '1' (step S120). If the hit flag is “1”, the state flag of the part object belonging to the primary change range, which is a range that collapses immediately after the hit, is set to “1” (step S130).

  Thereafter, the hit flag of the aggregate object is set to “2” (step S140).

  The state flag is provided for each part object constituting the collective object, and stores a value indicating the state of each part object. If the state flag of the part object is “0”, it indicates that the glass piece is in a normal state, “1” indicates that it is in a crushed state, and if it is “3”, it indicates that it is crushed. Indicates that it is the end.

  If the hit flag is not “1” and there is a process of changing with delay as described in FIGS. 9A to 9D, the state flag of the part object belonging to the delay change range is set to “1”. (Steps S150 and S160).

  When there is a process to change with delay, it is determined in advance how many frames are delayed to perform the change process. Then, it may be determined whether or not the frame has reached the frame, and the delay change process may be performed.

  If the hit flag is not '3', a part object display mode changing process is performed (step S170).

  Thereafter, based on the state flag and position coordinates of each part object, the display mode of each part object is determined and an image of the collective object is generated (step S180).

  FIG. 13 is a flowchart for explaining a more detailed processing example of the part object display mode changing process in step S170 of FIG.

  The processes of steps S210 to S250 are performed for all the part objects that constitute the aggregate object.

  First, if the status flag of each part object is “1”, the position coordinate of the pulverization pattern is calculated since it is in the pulverization state (step S220). The position coordinates of the pulverization pattern may be calculated based on, for example, the position coordinates of the part object in the previous frame and the drop speed.

  Based on the obtained position coordinates, it is determined whether the pulverization pattern has reached the floor (step S230). In this embodiment, since the change ends when the pulverization pattern reaches the floor, the state flag of the part object is set to “2” when the obtained position coordinates indicate that the pulverization pattern has reached the floor ( Step S240).

  When the processing of steps S210 to S240 is completed for all the part objects constituting the collective object, a search is performed as to whether or not there is a part object whose status flag is “1” in the part objects constituting the collective object (step 1). S260).

  If there is no part object whose status flag is “1”, all the changes due to the hit are completed, so the hit flag of the aggregate object is set to “3” (step S280).

3. Hardware Configuration Next, an example of a hardware configuration capable of realizing the present embodiment will be described with reference to FIG.
