In understanding the present invention, it is important to understand the technical background related to the calculation of the three-dimensional flight trajectory of a ball. Accordingly, taking a three-dimensional flight trajectory calculation of a golf ball as an example, the outline will be described within a range necessary for understanding the present invention. The following explanation is basically based on the paper “Aerodynamic measurement and three-dimensional flight trajectory analysis of golf balls” published in “Nagare 23 (2004) 203-211”. It should be noted that this is an example of the technical background of the present invention, and the present invention should not be construed in a limited manner by the paper.

First, in order to formulate the three-dimensional golf ball trajectory, a coordinate system and symbols are defined as shown in FIG. FIG. 5 shows a case where the golf ball is launched with respect to the X-axis (β ₀ = 0), and FIG. 5 shows a case where the ball is sliced and turns to the right. The direction is in the XY plane, the vertical direction is the Y axis, and the lateral blur direction is the Z axis.

The golf ball is launched at an initial velocity U ₀ and an elevation angle of α ₀ from the X axis, and the rotation axis Z _R is inclined from the Z axis by θ. During the flight, the drag force D, lift force L, gravity mg, and torque T (D, L, mg, T are vectors) are acting on the ball rotating at the rotation speed N, but the lift force L is the Y axis. Since the ball is tilted with respect to the direction, the ball bends while changing the side roll angle β every moment. The (Xt, Yt, Zt) coordinates in the figure are the movement coordinates with the ball center as the origin at time t.

Next, the mechanism by which the ball slices will be described with reference to the schematic diagram of FIG. X-axis horizontal component of the flight trajectory direction of the ball, Z-axis in the horizontal orthogonal axis direction, the vertical direction of gravity when the Y-axis, the ball in flight, rotating at backspin certain rotation axis Z _R around ( Rotational speed N (rps)). The direction of the rotation axis is determined when the ball leaves the club, and in the case of slicing, it is tilted to the right (rotation axis tilt angle θ (deg)).

The ball generates lift L depending on the rotational speed N. Since the lift L is perpendicular to the rotation axis, it is inclined to the right by the angle θ with respect to the vertical direction. For this reason, a force of Lsinθ acts in a direction perpendicular to the flying ball direction and in a lateral direction to the right, and this force becomes a driving force for bending the ball to the right. Then, it is considered that the inclination of the rotation axis is always inclined within a cross section perpendicular to the flying ball direction.

  Further, although the rotation speed N around the rotation axis of the golf ball is attenuated by the fluid torque T, the golf ball rotates at a high speed, and therefore the rotation axis tries to keep the direction of the rotation axis constant. Is assumed to be kept constant until the ball lands.

The magnitude | D | of the drag D, the magnitude | L | of the lift L, the magnitude | T | of the torque T are drag coefficients C _D , lift coefficient C _L , and fluid torque coefficient. Each is expressed as follows using C _m .
| D | = 0.5ρ | U | ² A * C _D (1)
| L | = 0.5ρ | U | ² A * C _L (2)
| T | = 0.5ρ | U | ² Ad * C _m (3)
Where ρ: air density, | U |: magnitude of the flying speed of the ball, A: golf ball diameter cross-sectional area, and d: golf ball diameter.

Here, the aerodynamic parameters of the drag coefficient C _D , the lift coefficient C _L , and the fluid torque coefficient C _m can be approximately expressed as a function of the rotational speed and flying speed of the ball. Each aerodynamic parameter is also dependent on the shape, arrangement and arrangement of dimples attached to the golf ball.

Drag (vector) D, it is the velocity (vector) U opposite direction of the ball, lift (vector) L is considering that such orthogonal speed of the ball and (vector) U to the rotation axis Z _R, It is possible to easily derive the equation of motion (differential equation) of the ball during flight. Given the initial velocity (vector), the direction of the axis of rotation, and the spin rate as the initial conditions, the flight trajectory of the ball and the rotation of the ball The speed can be obtained by numerical calculation (for example, Euler method).

  The GPU 12 performs a drawing process according to an instruction from the CPU 11 and displays a game image on the display unit 19. Further, the GPU 12 performs a drawing process in accordance with an instruction from the CPU 11 according to an operation input of the operation unit 16 by the user, and displays it on the display unit 19.

  The interface 13 controls data exchange between the CPU 11 and the operation unit 16 or a peripheral device (not shown).

  Next, an outline of an example of processing of the system 1 according to the embodiment of the present invention will be described based on an example of a golf game as shown in FIGS. 3, 4A, and 4B.

  When the execution of the golf game is instructed from the executable games displayed on the main menu screen (not shown), the golf game is started (S101), and the player character 102 is displayed on the game screen 100. In an initial screen (not shown), the player character 102 has a golf club (hereinafter simply referred to as “club”) 104 and is in a position to hit a golf ball (hereinafter simply referred to as “ball”) 106 (address). In the state).

In addition, a distance from the hitting position to the cup (here, Yard (Y)) is displayed at the top of the game screen 100, and an image obtained by shooting the golf course with the virtual camera from behind the player character 102 is used as a background image. Is displayed. Note that the viewpoint of the virtual camera may be a long-distance viewpoint or a bird's-eye viewpoint so that the state of the hall can be confirmed over a wide range.

  Next, as shown in FIG. 4A, a trajectory (ideal line) 110 for causing the player to perform an ideal slide operation is calculated and displayed on the game screen 100 (S102). Note that the ideal line 110 may draw different trajectories depending on the type of golf club selected by the player.

  As shown in FIG. 4A, the player designates the start position of the swing operation by touching an appropriate position near one end point of the ideal line 110 in the game screen 100, and slides in a predetermined direction corresponding to the backswing. When the operation is continued, touch information is sequentially acquired, and when the direction of the slide operation is reversed at an appropriate position near the other end point of the ideal line 110 (flick operation; see FIG. 4B), touch information at the time of reversal is also acquired (S103) . Then, a touch locus 120 is displayed on the game screen 100 based on the touch information. An arc-shaped touch index 130 representing the latest touch position is also displayed, but this touch index 130 is used to give an indication of the touch position because the touch position is hidden by a finger or the like during a slide operation. Is. Further, in order to distinguish the ideal line 110, the touch trajectory 120, and the touch index 130, the thickness and color of the line may be changed.

  In conjunction with the slide operation of the player, the player character 102 performs a backswing action, and an animation is displayed on the screen (see FIG. 4A). An animation is displayed on the screen so as to perform a downswing and follow-through operation after the flick operation described later (see FIG. 4B).

  Next, a flick motion is detected by analyzing touch information, and the speed and direction of the flick motion are acquired and output as flick information (S104). At that time, if necessary, the ideal line and the touch trajectory may be compared to obtain a deviation between them. Details will be described later.

  Next, based on the flick information, at least one of the ball flight conditions (eg, initial velocity (vector) of the ball, direction of the rotation axis, spin amount) is calculated and set (S105). Details of the flight condition calculation / setting method will be described later.

  Next, the flight of the ball is started based on the set flight condition, and the flight path of the ball 106 is sequentially calculated (S106). The principle of flight path calculation (three-dimensional flight trajectory calculation) is as described above.

  Next, the run (distance, direction) after the ball 106 has landed is calculated (S107). And the total flight distance of the ball | bowl containing the calculated | required run is displayed on the center of the game screen 100 as needed.

  Below, acquisition of touch information, analysis of touch information and acquisition of flick information, comparison between ideal line and touch trajectory, flight conditions based on flick information, etc. (ball initial velocity (vector), direction of rotation axis, spin rate) The details of the calculation / setting will be described.

Acquisition of touch information When the player performs a touch operation on the screen, the contact of an object with the touch screen is detected, and the start position of the touch operation corresponding to the start position of the swing operation is designated. Then, the touch position on the touch screen is detected and stored at a predetermined cycle (for example, a frame rate of 30 fbps).

  In this way, when the slide operation in a predetermined direction corresponding to the backswing is continued, the touch position information is sequentially acquired, and the slide operation from the touch start point is performed based on the touch position information recorded for each frame. A trajectory corresponding to is displayed on the screen. Thereby, the player can confirm the locus.

  The trajectory is drawn by connecting the touch position (coordinate position) of the previous frame and the touch position (coordinate position) of the current frame with a line, but the touch position (coordinate position) of the previous frame and the touch position of the current frame are drawn. By calculating the distance to (coordinate position) and dividing the calculated distance by the frame rate, the speed of the slide operation is calculated. Information on the speed of the slide operation is also stored as touch information.

Analysis of touch information and acquisition of flick information A flick action can be detected by analyzing the touch information. In order to detect the flick action, it is necessary to specify the reverse position of the slide operation. That is, when the touch position (coordinate position) of the previous frame and the touch position (coordinate position) of the current frame are connected by a line, the touch position (coordinate position) of the previous frame is set as the start point, and the touch position (coordinate position) of the current frame is obtained. A two-dimensional vector as the end point is obtained for each frame. The projection of the vector of the current frame (projection vector) is calculated with respect to the vector of the previous frame, and the direction of the vector of the previous frame and the projection of the current frame are calculated. When the vector directions differ by 180 °, the touch position of the previous frame may be set as the reverse position of the touch operation. In this case, the locus from the starting point position of the touch operation to the reverse position corresponds to a backswing.

  Then, since the two-dimensional vector having the start position of the reversal position of the slide operation and the end position of the slide operation by the flick operation is determined, the direction of the flick operation is acquired and the slide operation corresponding to the flick operation is performed. The speed of the flick operation is acquired from the speed. Further, information on the length of the locus from the start position of the touch operation corresponding to the backswing amount to the reverse position is also acquired.

Comparison of ideal line and touch trajectory When the ideal line trajectory is a curve obtained by projecting a curve on a predetermined spherical surface onto the screen, a virtual image obtained by projecting the center of the predetermined sphere onto the screen Find the intersection of the ideal line and the straight line that passes through the center point and the touch position for each frame, calculate the distance between the touch position and the intersection for each frame, and calculate the amount of deviation from the ideal line for each frame. Ask. The average of these deviation amounts is taken as the deviation amount from the ideal line. The shift amount is positive when the touch position is closer to the virtual center point than the ideal line, and negative when the touch position is far from the ideal line.

  In addition, although the case where the locus | trajectory of a touch position meanders and cross | intersects an ideal line and draws an S shape is assumed, in such a case, the amount of deviation will take a positive / negative value. In such a case, for example, when the total amount of positive displacement is larger than the total absolute value of negative displacement, the negative displacement amount is ignored and the average of the positive displacement amounts is set to the ideal line. You may make it employ | adopt as deviation | shift amount from. If the total absolute value of the negative deviation is greater than the total positive deviation, ignore the positive deviation and use the average of the negative deviation as the deviation from the ideal line. You may do it.

Calculation / setting of flight conditions (initial velocity (vector) of ball, direction of rotation axis, spin amount) based on flick information etc. Before explaining the method of setting flight conditions using information of player's touch operation, flick A method for acquiring a flight condition parameter based on information or the like will be described with reference to FIGS. 4A and 4B.

  A target area 140 is displayed in the upper right part of FIGS. 4A and 4B. The target area 140 is displayed as a circular area as shown in FIGS. 4A and 4B. By specifying the radius and declination by the circular coordinates fixed to the circular area, the collision position information is displayed. You can get it. Further, the radius of the circular region can be changed depending on, for example, the type of club. In addition, an auxiliary target area (not shown) is provided outside the target area 140, and even when it collides with this auxiliary target area, collision position information (radial radius and Declination).

  By the flick operation, the icon 150 is made to fly toward the target area 140 at the speed and direction of the flick operation. For example, assuming that the icon 150 is a mass point that flies with the speed and direction of the flick motion as the magnitude and direction of the initial velocity, respectively, and the mass point collides with the circular target region 140, the icon 150 The position where 150 collides with the target area 140 can be acquired as a radial coordinate radius and declination angle. Even when the icon 150 does not collide with the target area 140, the collision position information can be acquired in the same manner when the icon 150 collides with an auxiliary target area (not shown) provided outside the icon 150. Therefore, even if it collides with an auxiliary target area (not shown), it will be missed but not missed. However, when the auxiliary target area is also removed, it may be idle.

  Under the above assumption, an example of a method for setting a flight condition using information such as a flick action will be described.

The information acquired by the flicking operation is summarized as follows.
(A) Length of trajectory from start position of touch operation to reversal position (corresponding to backswing amount) (I) Radial radius and deviation of collision coordinates where icon collides with circular target area or auxiliary target area Corner (determined by the speed and direction of flicking)
(U) Deviation between ideal line and touch trajectory (deviation)

On the other hand, the parameters to be set as the initial conditions for flight are as follows as described above.
(A) Initial velocity magnitude (b) Initial lateral blur angle (c) Launch angle (elevation angle)
(D) Direction of rotation axis (e) Spin amount

  An example of the correspondence between parameters (a) to (e) to be set as initial conditions for flight and information (a) to (u) acquired by flicking or the like will be described in detail below. It should be noted that the following description is merely an example and is not limited thereto.

(1) Initial velocity of the ball (vector)
The initial velocity (vector) of the ball is determined by the magnitude of the initial velocity, the initial lateral blur angle, and the launch angle (elevation angle).
The magnitude of the initial speed is determined by the club head speed and the rebound performance of the ball, but the club head speed is highly correlated with the backswing amount, so the magnitude of the initial speed is the starting position of the touch operation. Is set as a function of the length of the trajectory from to the reversal position. In setting the initial speed, information on the speed of the flick operation may be taken into consideration.
The initial lateral blur angle is set as a function of the deviation amount from the ideal line, but as described above, the deviation amount can take a positive or negative value, and accordingly, the initial lateral blur angle also takes a positive or negative value. I can take it.
The launch angle (elevation angle) depends on the loft angle of the club used, and is set by adding a first correction amount to the reference launch angle determined for each club. In this case, the first correction amount is calculated, for example, by multiplying the output value of a predetermined evaluation function (evaluation function 1) using the radius and declination of the collision position as variables and a coefficient determined for each club. .

(2) Direction of rotation axis The direction of the rotation axis is, for example, another evaluation using a predetermined direction (for example, the positive X-axis direction) as a reference direction and the reference direction as a variable in the radius and angle of collision. It is determined by rotating around the Z-axis by the output value of the function (evaluation function 2).

(3) Spin amount The spin amount is set by adding a second correction amount to the reference spin amount determined for each club to be used. In this case, the second correction amount is calculated by multiplying the output value of still another evaluation function (evaluation function 3) using the radius and declination of the collision position as variables and a coefficient determined for each club.

  The function forms of the evaluation functions 1 to 3 may be set as appropriate. Further, instead of using a function, a table corresponding to the evaluation functions 1 to 3 may be prepared, and an output may be acquired by so-called table calculation.

  Also, regarding the run direction and distance when the ball lands and runs after flight, the ball bounces based on, for example, the speed (vector) at the time of landing of the ball, the rotational speed, the inclination of the landing point, the dynamic friction coefficient, etc. The run direction and distance can be simulated by numerically calculating the rolling and rolling. In addition, since the launch angle is considered to be a dominant factor, the run distance when hit with a driver can be set as a function of the launch angle as a simple method.

  As for the bounce behavior of the ball, it is necessary to consider that the spin and speed of the ball give energy to each other due to the dynamic friction coefficient of the ground, and that the reflection on the ground is attenuated by a repulsion coefficient. . Further, regarding the ball rolling, the angular velocity of the ball can be obtained after calculating the acceleration due to the downhill due to gravity and the acceleration due to the rolling resistance of the ground, and the distance over which the ball rolls can be obtained based on the angular velocity.

  As described above, the golf game has been described as an example. However, the present invention is not limited to this, and can be applied to a game in which a ball is hit or spun to fly, for example, a game using a baseball ball or a soccer ball. Needless to say.

  Each means constituting the system may be dedicated hardware, but is virtual means (so-called function realization means) realized at each processing stage by the computer executing a program. May be.

The system may be mounted on a game-dedicated device, but is mounted on a portable terminal such as a mobile phone, a smartphone, a PDA (Personal Digital Assistant), or a portable personal computer owned by the user. It may be a thing.

Furthermore, the system can be configured as a game system in which each process for executing a game is distributedly processed by a plurality of computers or the like.
