Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game image display method and control method, and more particularly to a game image display method and control method suitable for a baseball game.
[0002]
[Prior art]
With the development of computer graphics technology in recent years, so-called 3D games using three-dimensional stereoscopic image display are gradually becoming common in game devices in amusement facilities and home video game devices. Yes.
Baseball games are one of the most popular sports games that have a strong popularity. Also in this baseball game, a 3D game using a three-dimensional stereoscopic image display has appeared.
[0003]
In such a so-called 3D baseball game that can be displayed three-dimensionally, the vertical position and movement are easy to understand, but the movement of the depth with respect to the monitor screen is difficult to understand. In particular, since a ball in a baseball game is originally small, it is very difficult to display the depth movement and perspective on the monitor screen even though the position and movement are important.
[0004]
Also in 3D baseball games, it is possible to use various types of balls such as curves and shoots in addition to a straight ball for the pitcher, but the position of the ball only slightly changes on the display screen. And beginners hardly knew. Therefore, a new method for expressing the ball type in an easy-to-understand manner is awaited.
On the other hand, not only in 3D baseball games but also in 3D display games, characters and the like are represented by polygons. The shape of each part of the character was expressed as a polygon, and even when the position and orientation of the character changed, the position and orientation of the polygon were changed and expressed in a discontinuous manner. For this reason, even when there is a clothing line from the shoulder to the arm, if the polygon is twisted, it is discontinuous.
[0005]
Therefore, in order to smoothly connect polygon connection portions, proposals have been made to form a continuous shape by connecting the end faces of the polygons.
For example, when representing the sleeve part from the shoulder of the shirt covering the character's arm, the sleeve and shoulder of the shirt that are not deformed are represented by polygon A and polygon B, and the shape between them is the end face of polygon A. It expresses by connecting the vertices of the end faces of the polygon B.
[0006]
As for the shape between the two polygons A and B shown in FIG. 25A, the vertices a1, a2,..., A6 of the polygon A and the vertices b1, b2 of the polygon B are shown in FIG. ,..., B6 are connected to form a shape between the polygon A and the polygon B.
[0007]
[Problems to be solved by the invention]
When the polygon B is simply bent with respect to the polygon A, the vertexes a1, a2,..., A6 of the polygon A and the vertices b1, b2,. Connection shape is obtained. However, as shown in FIG. 25C, when the polygon A is twisted with respect to the polygon B, an unnatural dent is formed between the polygon A and the polygon B. Further, as shown in FIG. 25D, when the polygon A is twisted 180 degrees with respect to the polygon B, the thickness becomes almost unnatural between the polygon A and the polygon B. End up.
[0008]
For example, in the case of a movement that turns around the arm, the polygon A of the sleeve is twisted with respect to the polygon B of the shoulder. When this motion is expressed by the proposed method, it becomes an extremely unnatural shape in which the shoulder becomes thinner or thicker depending on the angle of twisting when the arm is rotated.
An object of the present invention is to provide a game image display method capable of expressing depth movement and perspective with respect to a monitor screen.
[0009]
Another object of the present invention is to provide a game image display method capable of expressing the difference in the types of balls thrown by a baseball pitcher or the like so that even a beginner can understand and enhancing the realism of the game.
It is still another object of the present invention to provide a game image display method capable of connecting twisted polygons in a natural shape.

[0035]
At the time of scoring, the 8-way lever 204 is used to specify the scoring when advancing or returning. The direction to advance or return is instructed by the 8-direction lever 204 to specify 塁. The A button 206 is used to instruct advancement, and the B button 208 is used to specify return. The bat type switch 210 is not used.
(Display the depth position of the ball)
Next, a display method of the depth position of the ball in the game apparatus according to the present embodiment will be described with reference to FIGS.
[0036]
When projecting a three-dimensional space onto a two-dimensional monitor screen, it is generally difficult to grasp the position of the ball in the three-dimensional space. In particular, when the ball moves from the back to the front, such as when the pitcher throws the ball, the position hardly changes on the two-dimensional monitor screen. was difficult.
In this embodiment, a circular cursor whose size and color changes is displayed around the ball, and as the ball gets closer to the monitor screen, the size of the cursor is reduced and the color is changed, and the depth position thereof is changed. Is displayed.
[0037]
3 to 8 show display screens when the pitcher throws the ball in the baseball game of the present embodiment.
First, FIG. 3 shows a stage where the pitcher tries to throw the ball. At this stage, since the pitcher has the ball, the ball is not displayed.
Next, when the pitcher throws the ball, a large circular cursor C is displayed around the ball B as shown in FIG. Thereafter, as the ball B approaches, the cursor C gradually decreases in size and converges on the ball B as shown in FIGS. 5, 6, 7, and 8. At this time, the color of the cursor C also changes from white to blue, yellow, and red, for example. The attacking player can know the timing of hitting from the size and color of the cursor C. For example, it can be used as a hint for the timing of hitting, such as pulling when hitting blue, returning the center when hitting yellow, and drifting when hitting red.
[0038]
As described above, according to the present embodiment, the depth of the ball thrown by the pitcher can be visually confirmed, and the batter can hit at a timing based on the information.
In the above embodiment, the size of the cursor C is reduced as the ball approaches. However, the size of the cursor C may be increased. Alternatively, the size may be increased to the middle as it approaches and then decreased. Further, the change in the size of the cursor C may be changed continuously according to the distance of the depth of the ball B, or may be changed stepwise.
[0039]
Also, the color of the cursor is not limited to the above embodiment, and may be changed in various colors in various forms.
(Indication of ball type)
Next, a display method of the ball type in the game apparatus of this embodiment will be described with reference to FIGS.
[0040]
When projecting a three-dimensional space onto a two-dimensional monitor screen, it is generally difficult to grasp the position of the ball in the three-dimensional space. In particular, when the ball moves from the back to the front, such as when the pitcher throws the ball, the position hardly changes on the two-dimensional monitor screen. Therefore, even if the pitcher throws a straight ball or throws a changing ball such as a curve or fork, there is only a slight difference in position on the two-dimensional monitor screen, and the pitch is output in an instant. Therefore, it was very difficult to know the type of ball thrown by the pitcher.
[0041]
In the present embodiment, the ball type thrown by the pitcher can be easily determined by changing the entire composition of the monitor screen according to the trajectory of the ball thrown by the pitcher, that is, the ball type. .
For example, when the pitcher throws a straight ball, the composition of the monitor screen is not changed, but when the pitcher throws a changing ball that changes mainly left and right, such as a curve, slider, chute, etc., the entire composition of the monitor screen When the pitcher throws a changing ball that changes mainly vertically, such as a fork or knuckle, the entire composition of the monitor screen is shaken up and down so that the player can easily determine the ball type. .
[0042]
9 to 11 are specific examples of the composition of the monitor screen when the pitcher throws a curve.
When the pitcher releases the ball to throw a curve, the composition of the game screen is not inclined at the time of release (position P1) as shown in the upper part of FIG. After the release, when the ball changes to position P2, position P3, position P4, and position P5, the game screen is changed according to this change in the lower part of FIG. 9, the upper part of FIG. As shown sequentially in the figure, when the ball rotates around the gazing point and the ball reaches the batter position P6, the rotation angle becomes maximum. The rotation angle θ of the composition of the game screen is defined as the rotation angle θ at the gazing point O of the composition as shown in FIG.
[0043]
When the position variation due to the curve increases, the rotation angle θ is increased to make it easy to intuitively grasp the degree of the curve.
Further, the physical strength consumption degree of the pitcher may be reflected in the rotation angle θ for rotating the composition. The physical wear level of the pitcher can be determined from the inclination of the composition.
As described above, according to the present embodiment, the composition of the screen fluctuates according to the trajectory of the ball thrown by the pitcher, so that the ball type can be easily determined.
[0044]
13 to 15 are other specific examples of the composition of the monitor screen when the pitcher throws a curve.
In the specific example described above, the overall composition of the game screen is changed, but only a part of the game screen may be changed as in this specific example. In this specific example, the batter, pitcher, and mound may not be changed, and only a part of the composition such as the home base or the batter box may be changed.
[0045]
When the pitcher releases the ball to throw a curve, the composition of the game screen is not inclined at the time of release (position P1) as shown in the upper part of FIG. After the release, when the ball changes to the position P2, the position P3, the position P4, and the position P5, the game screen is changed according to the change in the lower part of FIG. 13, the upper part of FIG. 14, the lower part of FIG. 14, and the upper part of FIG. As shown sequentially with the drawings, only a part of the composition such as the home base and batter box rotates, and the rotation angle becomes maximum when the ball reaches the batter position P6. The rotation angle θ of the composition of the game screen is defined as the rotation angle θ at the gazing point O of the composition as shown in FIG.
[0046]
As described above, according to the present embodiment, the composition of the screen fluctuates according to the trajectory of the ball thrown by the pitcher, so that the ball type can be easily determined.
(Polygon connection method)
Next, a method for connecting polygons in the game apparatus according to the present embodiment will be described with reference to FIGS.
[0047]
In 3D display games as well as 3D baseball games, characters and the like are represented by polygons. For joints such as the character's arms and legs, polygons are formed for the undeformed parts such as the shoulder, upper arm, forearm, and palm, and the corresponding vertices of the polygons are connected for the shape between these polygons. It represents an arm, a leg, etc. with movement.
[0048]
As shown in FIG. 16, when representing the sleeve portion from the shoulder of the shirt covering the character's arm, the sleeve and shoulder of the shirt that are not deformed are represented by polygon A and polygon B, and the shape between them is The polygon A and the polygon B are represented by being connected via a polygon S corresponding to a joint.
As shown in FIG. 17A, in this embodiment, a spherical polygon S corresponding to a joint is virtually arranged between the end face of the polygon A and the end face of the polygon B. Calculate the connection from the end face of the polygon A to the polygon S, calculate the connection from the end face of the polygon B to the polygon S, and finally connect the end face of the polygon A and the end face of the polygon B via the polygon S. To display a smooth connection state.
[0049]
First, as shown in FIG. 17B, the connection from the polygon A to the polygon S is calculated. A circumference R1 perpendicular to the vector OAOS from the center point OA of the polygon A to the center point OS of the polygon S is obtained. A point closest to the vertex a1 of the polygon A on the circumference R1 is defined as S11. As shown in FIG. 17C, points S12, S13, S14, S15, and S16 that are closest to the vertices a2, a3, a4, a5, and a6 of the polygon A are similarly determined on the circumference R1.
[0050]
Next, as shown in FIG. 17D, the connection from the polygon B to the polygon S is calculated. A circumference R2 perpendicular to the vector OBOS from the center point OB of the polygon B to the center point OS of the polygon S is obtained.
Next, as shown in FIG. 18A, a connection point candidate circumference R3 is obtained from the circumferences R1 and R2 of the polygon S. An axis passing through the intersections C1 and C2 between the circumference R1 and the circumference R2 is defined as C. A point on the circumference R1 perpendicular to the vector C1OS is designated as S1 ', and a point on the circumference R2 perpendicular to the vector C1OS is designated as S2'. At this time, an angle formed by the vector OSS1 ′ and the vector OSS2 ′ is θ. Therefore, as shown in FIG. 18B, the circumference on the polygon S formed by rotating the circumference R1 by θ / 2 around the axis C is defined as R3.
[0051]
Next, a coupling point is obtained from the coupling point candidate circumference of the circumference R2 and the circumference R3. First, as shown in FIG. 18C, the rotation angle φ between the points S1 ′ and S11 is obtained. Subsequently, as shown in FIG. 19A, a point obtained by rotating the point S3 ′ by φ on the circumference of the circumference R3 is set as S31, and similarly, points S32, S33, S34, S35 on the circumference R3 are set. , S36 is obtained. Subsequently, similarly, as shown in FIG. 19B, points S21, S22, S23, S24, S25, and S26 on the circumference R2 are obtained.
[0052]
Next, in order to obtain the connection from the polygon S to the polygon B, the polygon B is rotated by an angle φ about the vector OSOB as shown in FIG.
Next, the vertex ai of the end face of the polygon A, the vertex S1i of the circumference R1 of the polygon S, the vertex S3i of the circumference R3 of the polygon S, and the vertex S2i of the circumference R2 of the polygon S are obtained. And the apex bi of the end face of the polygon B are combined as shown in FIG. As a result, a smooth connection curve is obtained.
[0053]
As described above, according to this embodiment, even if a polygon to be coupled is twisted, it can be connected in a naturally smooth shape. In the case of the polygon A of the sleeve and the polygon B of the shoulder as shown in FIG. 16, even if the arm is raised and twisted as shown in FIGS. 21 and 22, the polygons A and B are smoothly passed through the polygon S. You can connect each other. As shown in FIG. 23, even if the arm is lowered and twisting occurs, the polygons A and B can be smoothly connected via the polygon S.
[0054]
(Character height display method)
Next, a character height display method in the game apparatus of the present embodiment will be described with reference to FIG.
For example, a large number of players appear in a baseball game, but since the movements of the players are obtained by calculation, the skeletons must be the same, and no separate character is prepared for each player. For this reason, even if it is another player, it will be expressed by the same character, and it tends to be poor in change.
[0055]
In the present embodiment, by changing the size of only the head portion of the character having the same skeleton, an illusion is used as if there are separate characters having different heights. As shown in FIG. 24, heads F1, F2, F3, and F4 that are different in size from the standard size head F0 are prepared and replaced as necessary. If the heads F1 and F2 smaller than the standard are used, the illusion is as if the character is tall, and if the heads F3 and F4 larger than the standard are used, the illusion is as if the character is short.
[0056]
(Modified embodiment)
The present invention is not limited to the above embodiment, and various modifications can be made.
For example, in the above embodiment, the present invention is applied to a baseball game, but the present invention may be applied to other games such as a shooting game, a soccer game, and a racing game. In the above embodiment, the bat type switch is used, but the hitting instruction may be issued by another switch.
[0057]
