Description

  The present invention relates to a three-dimensional image processing device, a game device, a three-dimensional image processing program, and a game program, and in particular, for example, a three-dimensional image processing device that draws an object in a virtual three-dimensional space on a display based on an operation of an operator. The present invention relates to a game device, a three-dimensional image processing program, and a game program.

  An example of this type of conventional three-dimensional image processing apparatus is disclosed in Patent Document 1. According to this patent document 1, the direction of the displayed three-dimensional object can be operated with the touch panel. Specifically, after touching a part of the displayed three-dimensional object, a target position for displaying the part of the three-dimensional object is further touched. Then, the three-dimensional object is rotated, and a part of the three-dimensional object touched first moves to the target position. When such a touch operation (so-called one-point input) is continuously performed along a certain trajectory, the three-dimensional object is displayed so as to rotate according to the trajectory.

Another example of this type of conventional three-dimensional image processing apparatus is disclosed in Patent Document 2. According to Patent Document 2, when a displayed three-dimensional object is touched, a rotation axis and a rotation direction when executing a rotation display process for the three-dimensional object based on the relationship between the touched position and the position of the screen center. To derive. Accordingly, the rotation of the three-dimensional object changes depending on the touched position on the screen. Further, when a certain point on the screen is continuously touched, the three-dimensional object continues to rotate.

  FIG. 3A and FIG. 3B are illustrative views showing examples of game screens displayed on the LCD 14 of the game apparatus 10 of this embodiment. FIG. 3A shows a game screen 100 displayed on the LCD 14, and a circular object 102 is displayed at the center of the game screen 100. However, since the game screen 100 displayed on the LCD 14 is a two-dimensional image, the object 102 is shown as a circle, but in the three-dimensional virtual space (game space), it is a sphere (ball) (see FIGS. 4 and 5). ). On the surface of the object 102, an image (for example, a face image) 104 of a specific character is displayed at a predetermined position.

  For example, an operator (hereinafter referred to as “player”) operates the touch panel 22 so as to stroke the stick 24 (drag operation, stroke operation), thereby rotating the object 102 and displaying it on the object surface. A face image 104 of a specific character (pasted) is displayed so as to be visible to the player himself. In FIGS. 3A and 3B, for the sake of easy understanding, characters other than the specific character are not shown, but in actuality, other characters may also be displayed. At this time, if the player rotates the object 102 so that the face image 104 of the specific character can be seen among all the characters within the time limit, that is, the state shown in FIG. If you can, the game is cleared. On the other hand, if the object 102 cannot be rotated so that the face image 104 of the specific character can be seen within the time limit, the game is over.

  FIG. 4 is an illustrative view conceptually showing the positional relationship between the object 102, the viewpoint (virtual camera), the virtual screen (LCD 14), and the touch panel 22. As shown in FIG. 4, a touch panel 22 is provided between the virtual screen (LCD 14) and the viewpoint (virtual camera). The LCD 14 projects a three-dimensional image (image taken by a virtual camera) including the object 102 viewed from the viewpoint onto a two-dimensional virtual screen, and the projected image (projected image) is shown in FIG. Alternatively, it is displayed as a game screen 100 as shown in FIG. Therefore, as described above, when it is determined whether or not the game is cleared, it is determined whether or not the face image 104 is facing the viewpoint position coordinate (viewpoint information) side. Strictly speaking, it is determined whether or not the face image 104 faces the viewpoint side based on the coordinates (Z value) of the predetermined position on the surface of the object 102 to which the face image 104 is pasted.

  Although not shown, for example, the LCD 12 displays a timer indicating the time limit for each stage, and also displays text or the like indicating that the game has been cleared or the game is over. For example, the timer is displayed to count down the time limit. Further, the number of cleared planes (stages) may be displayed. However, these may be displayed on the LCD 14.

  As described above, in this embodiment, the player performs a drag operation or a stroke operation (hereinafter referred to as “stroke operation”) on the touch panel 22 so as to rotate the object 102 displayed on the LCD 14 using the stick 24. Then, the object 102 is rotated in accordance with the stroke operation, and the state is displayed on the LCD 14.

  Here, for example, when rolling an actual sphere (ball) on a table, looking at the ball from above and touching the center with a finger and rolling it up and down or left and right, the ball moves up and down or left and right according to the movement of the finger. Rolls straight. However, when the finger is removed from the center of the ball, the ball is laterally rotated, so that it does not roll up and down or right and left.

  In order to realize such a feeling of operation, in this embodiment, different object drawing (rotation) processing is executed in accordance with the position on the object 102 where the player has made a stroke operation. For example, as shown in (i) of FIG. 5, when the stroke of the stick 24 is operated within the range indicated by (1) and (2), the object 102 is drawn as shown in FIG. 6 (A). Only the x and y components of the matrix (three-dimensional virtual space) are changed. Further, as shown in FIG. 5 (ii), when the stick 24 is stroked within the range shown in (2) and (3), the object 102 is drawn as shown in FIG. 6 (B). Change all x, y, and z components of the matrix.

  In this embodiment, the object 102 of the two-dimensional image is displayed on the LCD 14 so that the center thereof coincides with the center of the LCD 14 (and the touch panel 22) as shown in FIG. In addition, an operation effective area is set for the object 102 displayed on the LCD 14. Here, the operation effective area is an area for determining whether or not the object 102 is touched, and is set on the touch panel 22 corresponding to the display position of the object 102. Specifically, a coordinate group (coordinate data group) of the touch panel 22 corresponding to the display area of the object 102 is stored in the RAM 48. Here, the coordinates correspond to dots on the display surface of the LCD 14 and the detection surface of the touch panel 22. Further, as described above, since the number of dots on the display surface of the LCD 14 and the number of dots on the detection surface of the touch panel 22 are the same, the operation effective area can be easily set corresponding to the display position (display area) of the object 102. Can be set to

  In this embodiment, as shown in FIG. 6C, the operation effective area includes a first predetermined range (first area) 112 including the center of the object 102 and a second predetermined range (first area) other than the first area 112. 2 regions) 114. This is because, when the player performs a stroke operation on the object 102, it is considered that the player operates the object 102. Therefore, it is only necessary to determine whether or not the first region 112 is stroked. This is because the process is selectively executed.

  However, the size (range) of the first area 112 is set in advance by a game programmer or developer according to the size of the object 102 or the like.

  Therefore, when the player performs a stroke operation in the first area 112, the object 102 is rotated about the X axis and the Y axis as shown in FIG. When the player performs a stroke operation in the second area 114, that is, outside the first area, as shown in FIG. 6B, the object 102 is rotated about the X axis, the Y axis, and the Z axis. .

  Here, the angle (rotation angle) θ for rotating the object 102 is the touch coordinates (x1, y1) of the current frame (current frame) and the touch coordinates (x2, y2) of the previous frame (previous frame). (Δx, Δy) is detected and calculated based on the difference. Specifically, the rotation angle θ is calculated according to Equation 1. However, the touch coordinates are coordinates indicated by the coordinate data input from the touch panel 22.

[Equation 1]
θ = tan ⁻¹ (Δx / Δy)
Δx = x2−x1
Δy = y2−y1
The rotation angle θ calculated in this way is set for each axis of the matrix (three-dimensional coordinates) for drawing the object 102, and the object 102 has two axes (X axis and Y axis) with its center as the origin. Or it is rotated around three axes (X axis, Y axis and Z axis). The state is photographed by a virtual camera, and therefore the object 102 converted into a two-dimensional image is displayed on the LCD 14.

  However, when the player performs a stroke operation at the boundary between the first area 112 and the second area 114, that is, one of the touch coordinates of the current frame and the touch coordinates of the previous frame is within the first area 112, and the other Is within the second region 114, if the touch coordinates of the current frame are within the first region 112, the object 102 is rotated about two axes, and conversely, the touch coordinates of the current frame are the first region. If it is outside 112, the object 102 is rotated around three axes.

  FIG. 7 is an illustrative view showing an example of a memory map of the RAM 48 provided in the game apparatus 10. Referring to FIG. 7, RAM 48 includes a program storage area 480 and a data storage area 482. The program storage area 480 stores a game program. The game program includes a game main processing program 480a, a touch input detection program 480b, a coordinate change calculation program 480c, a rotation angle calculation program 480d, a touch coordinate determination program 420e, an object (three-dimensional (Image) Drawing program 480f, elapsed time count program 480g, game clear determination program 480h, and the like.

  The game main processing program 480a is a program for processing a main routine of a game (virtual game) executed on the game apparatus 10. The touch input detection program 420b detects the presence / absence of touch input (touch on / touch off) at regular intervals (one frame: screen update unit time), and turns on (established) / off (not established) a touch input flag 482c described later. ), And when there is a touch input, the coordinate data input from the touch panel 22 by the touch input is stored in the data storage area 482.

  The coordinate change calculation program 480c is a program for calculating changes in coordinates detected in the two frames, that is, Δx and Δy, when the touch-on state continues between the current frame and the immediately preceding frame. (Rotation angle calculation program) 480d is a program for calculating a rotation angle for rotating the object 102 according to Equation 1 based on the coordinate changes (Δx, Δy) calculated according to the coordinate change calculation program 480c. The touch coordinate determination program 480e is a program for determining whether or not the touch position detected according to the touch input detection program 480b is included in the first area 112 or the second area 114 set in the object 102.

  The object (three-dimensional image) drawing processing program 480f is a program for drawing the object 102 and other objects using object data 482b described later. The elapsed time count program 480g is a program for acquiring the count value of the internal timer omitted in FIG. 2 and counting the elapsed time of game play in each stage. That is, the timer displayed on the screen is counted down. The game clear determination program 480h is a program for determining whether or not the stage has been cleared. In this embodiment, within a time limit, the object 102 is rotated so that the face image 104 of the specific character pasted on the object 102 can be seen by the player, that is, the face image 104 is captured by the virtual camera. It is determined that the game is cleared. However, if the face image 104 is not visible to the player and the time limit is exceeded, that is, if the time is up, it is determined that the game is over.

  Although not shown, the program storage area 480 also stores a sound reproduction program, a backup program, and the like. The sound reproduction program is a program for reproducing sound (music) necessary for the game. Further, the backup program is a program for storing (saving) mid-game data and result data in the RAM 28b of the memory card 28 in accordance with a player instruction or a predetermined event.

  In the data storage area 482, a touch coordinate buffer 482a is provided. The touch coordinate buffer 482a has an area where coordinate data for at least two frames can be stored, and stores coordinate data detected according to the touch input detection program 480b. In this embodiment, the touch coordinate buffer 482a stores the coordinate data of the current frame and the coordinate data of the previous frame. The data storage area 482 stores object data 482b. The object data 482 includes polygon data, position data (three-dimensional coordinate data), and texture data.

  Further, a touch input flag 482c is stored in the data storage area 482. The touch input flag 482c is turned on / off according to the touch input detection program 480b as described above. In this embodiment, the touch input flag 482c is configured by a 1-bit register. When the touch input is turned on, the register data value is set to “1”, and when the touch input is turned off, the data value of the register is set. Is set to “0”.

  Furthermore, an operation effective area 482d is stored (set) in the data storage area 482. As described above, the operation effective area is coordinate group data (coordinate data group) corresponding to the first area 112 and the second area 114. However, as described above, in this embodiment, since it is only determined whether or not the player's scroll operation is included in the first area 112, only the coordinate data group corresponding to the first storage area 112 is stored. You may make it memorize | store.

  Although illustration is omitted, in the data storage area 482, sound (music) data for outputting a sound necessary for the game, data (game intermediate data, result data) generated as the game progresses, A flag (event flag) is also stored.

  Specifically, the operation as described above is executed by the CPU core 42 shown in FIG. 2 according to the flowcharts shown in FIGS. Referring to FIG. 8, when starting the game process, CPU core 42 performs initial setting in step S1. Specifically, the buffer area and flag of the data storage area 482 are reset. It also resets and starts the internal timer and starts counting the time limit. Furthermore, when the game is started from the previous continuation, the game data is loaded from the RAM 28b of the memory card 28.

  In the subsequent step S3, the object 102 is drawn in an initial state. That is, using the object data 482b, the object 102 is drawn at a predetermined position (initial position) in the three-dimensional virtual space and displayed on the LCD 14. At this time, the texture of the face image 104 is pasted at a predetermined position on the surface of the object 102. However, when the game is started from the beginning, the object 102 for the first stage is drawn, and when the game is started from the continuation, the object 102 for the continuation stage is drawn. In step S3, as will be described later, in the game end determination (S29), if it is not determined that the game ends after the game is cleared, the object 102 for the next stage is drawn, and the game ends after the game is over. If not, the object 102 for the same stage is drawn. In step S5, an operation effective area of the object 102, that is, the first area 112 and the second area 114 are set. However, as described above, in this embodiment, the coordinate data group corresponding to the first area 112 is stored in the data storage area 482.

  Subsequently, in step S7, a touch input is detected. Specifically, coordinate data input from the touch panel 22 is detected. In the next step S9, it is determined whether or not there is a touch input, that is, whether or not coordinate data is input. If “NO” in the step S9, that is, if coordinate data is not input from the touch panel 22, it is determined that there is no touch input (touch-off), and in a step S11, the touch input flag 482c is turned off, and FIG. It progresses to step S21 shown.

  However, if “YES” in the step S9, that is, if coordinate data is input from the touch panel 22, it is determined that there is a touch input (touch-on), and touch coordinates (coordinate data) indicated by the touch input in a step S13. Is stored (temporarily stored) in the coordinate buffer 482a of the data storage area 482, and in step S15, it is determined whether or not the touch input flag 482c is on. If “NO” in the step S15, that is, if the touch input flag 482c is turned off, it is determined that the stroke operation is not performed because the touch-off state is changed to the touch-on state, and the touch input flag 482c is determined in a step S17. And the process proceeds to step S21. On the other hand, if “YES” in the step S15, that is, if the touch input flag 482c is turned on, it is determined that the operation is a stroke operation because the touch-on state continues, and an object drawing process described later is performed in a step S19. After executing (see FIG. 10), the process proceeds to step S21.

  In step S21 shown in FIG. 9, it is determined whether the time limit has elapsed. That is, it is determined whether the time is up. If “YES” in the step S21, that is, if the time limit has elapsed, a game over process is executed in a step S27, and the process proceeds to a step S29. For example, in step S27, a game screen expressing that the game is over is displayed on the LCD 14 (or LCD 12), and then a selection screen for selecting whether or not to continue the game is displayed on the LCD 14 (or Displayed on the LCD 12).

  However, if “NO” in the step S21, that is, if the time limit has not elapsed, it is determined whether or not a predetermined texture exists on the viewpoint side in a step S23. In this embodiment, as described above, it is determined whether or not the face image 104 of a specific character exists on the virtual camera side. If “NO” in the step S23, that is, if the predetermined texture does not exist on the viewpoint side, the process returns to the step S7 shown in FIG. 8 as it is. On the other hand, if “YES” in the step S23, that is, if a predetermined texture exists on the viewpoint side, a game clear process is executed in a step S25, and the process proceeds to a step S29. For example, in step S25, a game screen expressing that the game has been cleared is displayed on the LCD 14 (or LCD 12), and then a selection screen for selecting whether or not to proceed to the next stage is displayed on the LCD 14 (or LCD 12). ). Also, the processing may be performed such as increasing (raising) the level or life of the player. However, if all stages are cleared, end roll display is executed.

  In step S29, it is determined whether or not the game is over. Specifically, it is determined whether an instruction to end the game is input by the player or the game is over. If “NO” in the step S29, that is, if the game is not ended, the process returns to the step S1 shown in FIG. On the other hand, if “YES” in the step S29, that is, if the game is ended, the game process is ended.

  Note that the scan time of the game process shown in FIGS. 8 and 9 is a fixed time (one frame period), and therefore the touch input detection process (S7) is executed every fixed time.

  FIG. 10 is a flowchart showing the object drawing process of step S19 shown in FIG. Referring to FIG. 10, when starting the object drawing process, the CPU core 42 reads the touch coordinates (coordinate data) of the previous frame and the current frame from the touch coordinate buffer 482a in step S41. In the following step S43, change values (Δx, Δy) between the touch coordinates of the previous frame and the touch coordinates of the current frame are calculated. Next, in step S45, the rotation angle θ of the object 102 is calculated according to Equation 1.

  In step S47, it is determined whether the touch coordinates of the current frame are within the first area 112. If “YES” in the step S47, that is, if the touch coordinates of the current frame are within the first region 112, the rotation of the x component and the y component of the object drawing matrix (three-dimensional coordinates) is performed in a step S49. The rotation angle θ calculated in step S45 is set in the angle, and the process proceeds to step S53.

  However, if “NO” in the step S47, that is, if the touch coordinates of the current frame are within the second region 114, the x component and the y component of the object drawing matrix (virtual three-dimensional space) in a step S51. The rotation angle calculated in step S45 is set (set) to the rotation angle of the, z components, and the process proceeds to step S53.

  In this embodiment, in step S47, it is determined whether or not the touch coordinates of the current frame are within the first area 112, but whether or not the touch coordinates of the previous frame are within the first area 112. It may be determined whether or not.

  In step S53, rotation drawing processing of the object 102 is executed. That is, in step S49 or step S51, according to the rotation angle θ set in the three-dimensional virtual space, around two axes (around the X axis and around the Y axis) or around three axes (around the X axis and around the Y axis) And around the Z axis). In a succeeding step S55, a texture pasting process is executed. Here, as described above, the texture of the face image 104 of a specific character is pasted around a predetermined position on the surface of the object 102.

  Subsequently, in step S57, viewpoint conversion processing is executed. That is, the coordinates (X axis, Y axis, Z axis) are converted (rotated and translated) in the three-dimensional virtual space (game space) so that the viewpoint (virtual camera) position is the center (origin). . In step S59, the projection conversion process is executed, and the object drawing process is returned. That is, in step S59, the three-dimensional virtual space viewed from the viewpoint (virtual camera) is projected onto the virtual screen. As a result, the three-dimensional virtual space viewed from the viewpoint is converted into a two-dimensional game image, and thus the game screen 100 as described above is displayed on the LCD 14.

  According to this embodiment, the rotation of the object can be performed by a stroke operation, and different rotation processing is performed depending on whether the area or position on the object to be stroked is near the center and other areas. A new feeling of operation as if it is rolling can be obtained.

  Also, since the rotation angle is simply calculated based on the amount of change in touch coordinates due to the stroke operation, the processing load can be relatively reduced and the burden on the game processing can be reduced.

  In this embodiment, the rotation angle is calculated based on the change amount of the touch coordinates of two consecutive frames. However, the rotation angle is calculated based on the change amount of the touch coordinates of three or more consecutive frames. May be. However, as the number of consecutive frames increases, the amount of rotation (movement) of the object increases and the display becomes complicated, so it is necessary to set the number of frames to such an extent that the sense of reality is not lost.

  In this embodiment, the case where a spherical object is displayed on the LCD has been described. However, an object having another shape may be displayed.

  Furthermore, in this embodiment, the case where two LCDs are provided and two game screens are displayed has been described. However, one LCD is provided, and a touch panel is provided correspondingly, and one game is provided on the LCD. A screen may be displayed.

  Furthermore, in this embodiment, the game apparatus provided with two LCDs has been described, but the display area of one LCD is divided into two, and a touch panel is provided corresponding to at least one of the display areas. May be. In this case, when a vertically long LCD is provided, the LCD display area is divided so that two display areas are arranged vertically, and when a horizontally long LCD is provided, the LCD is arranged such that two display areas are arranged horizontally. The display area may be divided.

  The above is one embodiment (first embodiment) of the present invention, but various other embodiments are also conceivable. Hereinafter, another embodiment (second embodiment) of the present invention will be described.

  The game apparatus 10 according to the second embodiment displays the one or more objects 102 at any position on the LCD 14 and sets the effective operation area for each of the objects 102 described above. Since it is the same as 1 Example, the overlapping description is abbreviate | omitted.

  FIG. 11A is an illustrative view showing an operation effective area set for the object 102 of the second embodiment. As can be seen with reference to FIG. 11A, the first area 112 is set to a predetermined range including the center of the object 102 as described in the first embodiment. However, the second region 114 is outside the first region 112 and is set in a ring shape so as to surround the first region 112. The size (range) of the first area 112 is set in advance by the game programmer or developer according to the size of the object 102 or the like, as in the first embodiment. In addition, the second area 114 is similarly set as appropriate according to the size (range) of the object 102 and the first area 112.

  Note that the second region 112 is set to protrude slightly from the object 102 even when the player scrolls the outer periphery of the object 102 with the stick 24 or the like. This is because it is displayed on the screen.

  Thus, in the second embodiment, the first area 112 and the second area 114 are set corresponding to the position of one object 102 (the position in the three-dimensional space or the display position calculated based on the position). Thus, as shown in FIG. 11B, the object 102 can be displayed at an arbitrary position on the LCD 14 (or the game screen 100). Further, as shown in FIG. 11C, a plurality of (here, three) objects 102 can be displayed on the LCD 14 (arbitrary positions). Further, as can be seen from FIG. 11C, the size of the object 102 can be freely set. Therefore, when one object 102 is displayed at an arbitrary position on the LCD 14, the operation effective area 482 d shown in the first embodiment includes coordinate data groups for the first area 112 and the second area 114 ( Data of a predetermined range of position coordinates corresponding to each of the first region 112 and the second region 114, or information data regarding the range of coordinate data) is stored. When a plurality of objects 102 are displayed on the LCD 14, the coordinate data group of the first area 112 and the second area 114 is stored for each object 102.

  In this way, if an operation effective area is set for each object 102, the coordinates of the corresponding three-dimensional space are calculated based on the touch position of one object 102 instructed (touch input) by the player. Can be determined. Therefore, for example, when displaying a plurality of objects, it is possible to rotate the object 102 so that the player can see all the facial images 104 of the specific character pasted on each object 102 within the time limit. It can be determined that the game is cleared. On the other hand, if the object 102 cannot be rotated so that all the face images 104 of a specific character pasted on each object 102 can be seen by the player within the time limit, that is, any one face image 104 If the object 102 cannot be rotated so that it can be seen by the player, it can be determined that the game is over.

  Further, for example, the face image 104 of a specific character can be pasted on any one of a plurality of objects, and the face image 104 of the object 102 can be rotated so that it can be seen by the player within the time limit. Sometimes it can be determined that the game is clear. In such a case, when the face image 104 of the object 102 cannot be rotated so as to be visible to the player within the time limit, it is determined that the game is over.

  As described above, in the second embodiment, it is possible to enjoy a game having a higher difficulty level (level) than the game shown in the above-described embodiment.

  Note that the determination of game clear or game over when one object 102 is displayed on the LCD 14 is the same as the case shown in the first embodiment.

  In the second embodiment, an object drawing process (see FIG. 12) similar to the object drawing process (see FIG. 10) shown in the first embodiment is executed, but two or more objects 102 are displayed on the LCD 14. When displayed, an object drawing process (FIG. 12) is executed for each object 102.

  Note that the game processing described with reference to FIGS. 8 and 9 is substantially the same in the second embodiment, and thus redundant description is omitted. The difference from the first embodiment is that two or more objects 102 may be drawn in step S3, and if two or more objects 102 are drawn, an operation is performed on each object in step S5. The effective area is set. When two or more objects 102 are drawn, the game clear or game over determination process (S21, S23) is slightly different from the first embodiment as described above.

  FIG. 12 is a flowchart showing object drawing processing of the second embodiment. As described above, this object drawing process is substantially the same as the object drawing process of the first embodiment, and thus a duplicate description is omitted. In FIG. 12, the same reference numerals are assigned to the same processes as those in the first embodiment. Further, for convenience of drawing, illustration of a part of the same processing as the object drawing processing shown in FIG. 10 is omitted.

  Referring to FIG. 12, when the CPU core 42 starts the object drawing process and executes the processes of steps S41 to S45, the touch coordinates of the previous frame and the touch coordinates (two touch coordinates) of the current frame are obtained in step S46. It is determined whether or not it is included in (corresponding to) the first area 112 or the second area 114. That is, it is determined whether or not the player has performed a stroke operation within the operation effective area. If “NO” in the step S46, that is, if one or both of the two touch coordinates are not included in the first area 112 or the second area 114, the object drawing process is returned as it is. On the other hand, if “YES” in the step S46, that is, if two touch coordinates are included in (corresponding to) the first area 112 or the second area 114, the process proceeds to a step S47. Since the processing after step S47 is the same as that of the first embodiment, repeated explanation is omitted.

  In the second embodiment, as in the first embodiment, it is possible to obtain an operational feeling as if the object is actually touched, and the processing load of the object drawing process can be reduced.

  In the second embodiment, the setting range of the operation effective area for the object is set to the same range (size) as the display area of the object, so that one or more objects can be displayed at an arbitrary position. Each object can be rotated by the stroke operation of the player.
