[0021]

FIG. 1 is a block diagram showing an example of the arrangement of an image processing apparatus in which the animation generation program of the present invention is executed.

The program processing unit 1 is a CPU, which has the function of a main processor, and has a program storage memory 2.
Is an optical disk (CD, DVD), a magneto-optical disk (M
O), a hard disk, etc., and stores a game program including the animation generation program of the present invention, object data, and the like.

The program processing unit 1 controls the progress of the game based on the game program including the animation generation program of the present invention stored in the program storage memory 2 or transferred from the program supply source through a communication interface unit (not shown).

The object data having the local coordinate data is transferred and stored in the main memory 4 for the processing in the image processing section 3 from the program processing section 1 as the game progresses.

The image processing section 3 has a geometry processing section 30 and a rendering processing section 31. The geometry processing unit 30 converts the local coordinates in the vertex data of the polygon, which is the attribute of the object data transferred by the program processing unit 1, into the world coordinate system, and further performs the coordinate conversion from the world coordinate system into the viewpoint coordinate system. .

In the geometry processing unit 30, the object data converted into the viewpoint coordinate system is the texture data at the vertices of the polygon (data that determines which texture address is assigned to the vertices of the polygon),
It has vertex data of a three-dimensional viewpoint coordinate system including brightness data and the like. This object data is stored and held in the main memory 4 for work.

The rendering processing unit 31 includes a texture function unit (not shown) and responds to changes in the wave of the viewpoint coordinate system composed of a plurality of polygons generated according to the features of the present invention, which will be described in detail later. The texture data stored in a texture memory (not shown) is pasted (mapping) to the object data.

The data drawn in the frame memory 310 is repeatedly read, converted into a video signal, and displayed on the display 6.

FIG. 2 is a processing flow in executing the animation generation program of the present invention. An animation generation program of the present invention is a program portion for performing background image processing in a surfing game as an embodiment, and
It is included in a program that executes a surfing game together with a program portion that performs image processing of objects such as surfers and surfboards, which are objects that change in response to the player's operation of the input device.

However, the animation generating program of the present invention is not limited to the program for executing such a surfing game, but can be executed as a single program or in combination with other programs.

FIG. 3 shows images of a coast (BEACH) and a sea (SEA) placed in a virtual three-dimensional space, and a wave (WAVE) generated on the sea (SEA) and changing with time. There is. The wave (WAVE) travels in one direction, for example, the X-axis direction and the Z-axis direction (the direction from the depth to the front) which is a direction intersecting with the X-axis direction. An image captured with the camera 100 placed in this virtual three-dimensional space as a viewpoint is converted into two-dimensional coordinates and displayed on the display 6.

Note that, in FIG. 3, the viewpoint position of the camera 100 is not limited to the case where it is placed behind the surfer and the surfboard, which are characters operated by the player, and may be the subjective viewpoint of the surfer itself. is there.

FIG. 4 shows a wave (WAV) displayed on the display 6 by capturing the position of the camera 100 as a viewpoint.
It is an example of the image of E). Further, the images of the surfboard and the surfer 101 are displayed in an overlapping manner so as to surf on the image of the wave.

For the images of the surfboard and the surfer 101, the object data required by the program processing unit 1 is transferred to the image processing unit 3 by the execution of the program for controlling them in the game program, and the coordinate conversion and texture are performed there. Mapping processing is performed. At this time, when the object data of the image of the surfboard and the surfer 101 overlapping the image of the wave (WAVE) is subjected to the rendering process, the polygons forming the image of the surfboard and the surfer 101 are processed with higher priority.

Here, as shown in FIG. 5, a change in the propagation of waves in the natural world is shown in one direction, for example, the X direction (arrow direction I) and the Z direction (arrow direction II) which is a direction perpendicular thereto. I think I have. At this time, in FIG. 5, positions at predetermined intervals in the arrow direction I have elapsed time in sequence,
At the same time, it has a waveform change in the arrow direction II.

Assuming a wave change image as shown in FIG. 3 and corresponding FIG. 4, for example, positions I and I in the X direction are used.
I and III respectively correspond to different elapsed times, and have cross-sectional waveforms I, II, and III of waves that change with the passage of time.

The first feature of the present invention is to obtain the cross-sectional waveform of the wave corresponding to such elapsed time. Returning to FIG. 2, as a premise for executing the animation generation program of the present invention for displaying a wave change image, a plurality of registered key frames corresponding to elapsed time are stored as program data stored in the program storage memory 2. Have a pattern.

FIG. 6 shows an example of a plurality of key frame patterns registered as program data corresponding to the elapsed time, and corresponds to three different elapsed times which are successively increased in FIGS. 6A, 6B and 6C. Keyframe pattern
I, II, III are shown. Connection points (a to h, a'to j ', a "to the frames that form the key frame pattern
k ″) each have three-dimensional position coordinates.

Now, consider a plurality of predetermined positions I, II, and III in the X direction in FIG. These positions I, II, III each have a corresponding elapsed time, at which point in FIG.
It is considered that the keyframe patterns I, II, and III of are corresponding.

In FIG. 3, a plurality of positions are specified at predetermined intervals in the X direction, and the cross-sectional waveform of the wave at each position is obtained as follows.

One of a plurality of predetermined interval positions, for example, two registered key frame patterns II (see FIG. 6).
Consider the elapsed time position x lying between the elapsed time positions II and III corresponding to B) and III (FIG. 6C). Program processing unit 1
First, the key frame patterns II and III corresponding to the predetermined elapsed time positions II and III before and after the elapsed time position x are read from the main memory 4 (processing step P).
1).

Then, as shown in FIG. 7, the key frame patterns II and III are subjected to curve interpolation (processing step P2). This curve interpolation is performed for the elapsed time positions II and III of the elapsed time position x.
The interpolation amount is determined according to the size ratio of the distance from. Key frame pattern II according to the determined interpolation amount
And the interpolated three-dimensional coordinates of the connection points forming III are obtained.

For example, assuming that the elapsed time position x is at an intermediate time position between the elapsed time positions II and III, the coordinates of the connection points forming the frame pattern corresponding to the elapsed time position x obtained by curve interpolation are , Keyframe pattern
It is the intermediate value of the coordinates of the connection points of II and III.

In this way, the elapsed time position x is obtained by curve interpolation.
A frame pattern corresponding to is obtained, but at this time, a predetermined parameter correction is performed (processing step P3).

8 to 14 are views for explaining the parameter correction. The correction is performed by adding or subtracting the correction value to the coordinate value of the connection point according to the characteristic of each parameter correction.

Such parameter correction is carried out along with the parameter correction value for the arithmetic processing in the program processing unit 1 so that it is executed in the progress of the program.
This can be executed by including a command instructing parameter correction in the program.

FIG. 8 shows the parameter correction for determining the section (x) using the following parameter correction values,
Arrows indicate the intervals. It corresponds to the plurality of predetermined spacing positions described above with reference to FIGS.

FIG. 9 is a parameter correction showing the place where the wave is generated (ZST) when viewed from the upper direction, that is, the Y-axis direction. Corresponding to the section (x) position using each parameter, the wave generation position, that is, the beach (BEA) in FIG.
This is the initial position of the wave in the CH) direction (Z direction = direction II: see FIG. 5). At each position (x),
When the place where the wave is generated (ZST) is different, the wave is not a straight wave, but a wave having unevenness as shown in FIG.

FIG. 10 shows where the wave ends (ZEN
It is a parameter correction showing D). This is a process to prevent the wave crest from diving into the terrain during wave deformation. When a predetermined coordinate position is reached by the curve interpolation described in FIG.
Parameter correction is performed so that the cross section of the wave shown in the order of A → B → C becomes gradually flat and disappears.

Similar to FIG. 9, FIG. 11 shows an upward direction, that is, Y.
Shore (BEACH) direction (Z direction = when viewed from the axial direction)
Direction II: Parameter correction that changes the speed of movement in the direction of FIG. The crest position is gradually opened according to the elapsed time of T0, T1, T2, ...
This represents a change in speed in the shore (BEACH) direction of the wave.

FIG. 12 is a parameter correction for giving a shape change (TUBE) to the wave in the width direction. By adding or subtracting the parameter correction values, the shape of the wave width is changed as shown in the cross sections of the waves in FIGS. 12A and 12B.

FIG. 13 is a parameter correction that gives a shape change (HEIG) in the wave height direction. A parameter correction value is added or subtracted to change the shape of the wave height as shown in FIGS. 12A and 12B.

FIG. 14 shows the setting of the initial key frame (ST
It is a parameter correction that gives AT). In order to give the wave shape an undulation, for example, as shown in FIG.
As shown in B, a key frame as an initial value is set.
As a result, it is possible to make the wave shape uneven as shown in FIG. 14C.

Returning to the processing flow of FIG. 2, after the predetermined parameter correction (processing step P3) is executed, the obtained outline is interpolated into a curve (processing step P4). This curve interpolation is realized by, for example, spline interpolation.

FIG. 15 is a diagram for explaining the actual curve interpolation. As described with reference to FIG. 7, in the frame pattern of the wave at the predetermined time position x obtained from the key frame in consideration of the parameter interpolation, The spline interpolation values are calculated separately for the upper surface (FIG. 15A) and the lower surface (FIG. 15B) of the wave, and the linear frame pattern of the wave is converted into the curved frame pattern (FIG. 15C).

Then, coordinate points are calculated for each predetermined length for the obtained frame pattern of the curve (FIG. 16A),
Complete the model data (FIG. 16B) (processing step P
5). In this way, the connection points (coordinate points) of the plurality of waveform model data obtained for the elapsed time positions at the predetermined intervals are set to X.
A polygon figure representing the shape of the wave is created by connecting to the direction (see FIG. 3) (processing step P6).

At this time, as shown in FIG. 16A, in the setting of the predetermined length for calculating the coordinate points, the predetermined length is shortened toward the tip of the wave on the lower surface of the wave (see FIG. 15B). It is desirable to do. This can more smoothly represent the wave entrainment and can efficiently determine the size of the polygon.

FIG. 17 shows an example of the polygonal figure of the wave formed in the processing step P6. It is composed of multiple trigonometric polygons. The bar standing at the apex of each polygon is a normal vector representing the orientation of the polygon surface. FIG. 18 is a cross-sectional view at a certain position in the X direction of the wave polygonal pattern shown in FIG. 17, and it can be understood that the cross-sectional shape changes from I to VI with the passage of time.

Here, the waves in the natural world have splashes on the wave crests, collapsed wave crests, or change in transparency in the state where time has elapsed. Representing such a state as an effect is an animation image of waves that gives a more realistic feeling.

FIG. 19 is a diagram showing a method according to the present invention for displaying an image of a state at an elapsed time just before the beginning of a wave falls on the sea surface.

I in FIG. 19 is a cross-sectional model of the wave at the time elapsed just before the head falls to the sea surface, and II in FIG.
[Fig. 4] is an enlarged view of a leading portion. A splashing polygon A is attached to the cross-sectional portion B at the beginning of the wave. Also, FIG.
III of 9 is the collapse portion C of the tip of the wave. A polygon with a predetermined transparency is added to represent the collapsed portion C at the tip.

In this way, the splash A at the beginning of the wave and the polygon representing the collapsed portion C are prepared as program data in advance in the program storage memory 2 together with the program. Then, in the wave pattern after a predetermined time has passed, the program processing unit 1 performs an operation so that these program data are pasted to the coordinate positions of the head portion, thereby expressing the splash A or the collapsed portion C of the head portion. be able to.

FIG. 20 is a diagram for explaining a method of representing how the top of a wave increases in transparency due to splashing or breaking. In the cross-sectional frame pattern of the wave after the predetermined elapsed time, the opacity of the connection point in the Z direction is reduced from 100% to 90, 70, 50% as shown in FIG.

The method of changing the transparency at the beginning of the wave has other applications. When the polygon is formed by the wire frame II as shown in FIG. 21A, the wave spreads according to the elapsed time. The wave part becomes isolated from the surrounding sea part, resulting in an animation image of the wave. It is unnatural.

Therefore, in the present invention, as shown in FIG. 21B, the transparency is gradually increased at the tip of the region where the wave spreads with the lapse of time, so that the wave is adapted to the surroundings.

As described above, the polygon data for which the transparency has been determined and the effect model has been created (processing step P7) for the polygon model for which the predetermined time has elapsed is processed by the texture mapping unit 31 of the image processing unit 3 to determine the vertex of the polygon. A texture is attached based on the data and the direction of the normal vector, and the transparency is set (processing step P8).
At this time, the background image is also drawn at the same time with a predetermined priority process.

Next, the polygon data to which the texture is pasted is perspective-transformed by the rendering processing unit 31 to be transformed into two-dimensional coordinate data, and the frame memory 6
Written in. The two-dimensional coordinate data is repeatedly read from the frame memory 6, converted into a video signal, and displayed on the display 6 (processing step P9).

Here, it is assumed in the present invention that the application of the present invention is provided to a game device in which a player operates a surfer as a character. When the surfer travels in a wave tunnel (hollow tube shape) using the change in transparency at the beginning of the wave or the effect of splashing described with reference to FIGS. 19 and 20, a more virtual reality is obtained. It is possible to increase.

FIG. 22 is an image of the front of the tunnel when the camera viewpoint 100 is placed in the wave tunnel A1. As the background B1 ahead of the tunnel,
The horizon and clouds above it are displayed. On the other hand, the left side of the screen, that is, the area A2 at the beginning of the wave is made highly transparent so as to be semitransparent or transparent as described above with reference to FIG.

Therefore, a wider background B2 is displayed so that it can be seen through the area A2 at the beginning of the wave. As a result, the player can easily grasp the situation of the direction in which he / she should proceed even in the wave tunnel and operate the character. In FIG. 22, the tip A of the wave
Reference numeral 3 is a portion representing the splash and the collapse of the waves as described with reference to FIG.

Alternatively, the rotary connecting rod has an angle opposite to that shown in FIG. 24A, that is, the horizontal portion 200 and the rising portion 20.
By setting the angle 1 to be smaller than 90 °, when the operation board 23 is slid to the left and right, the operation board 23 is lifted. This allows the player 24 to imitate the resistance of the surfboard when it receives a wave.
