Method of collision simulation for spinning ball

Abstract

Disclosed is a method of simulating a collision trajectory of a ball which rotates and moves in a virtual sports game (for example, golf, baseball, soccer, or tennis). A method of collision simulation for a spinning ball includes: detecting collision of a spinning ball; calculating a velocity of the ball after colliding considering rotation of the ball and the friction with the ground; calculating a center point of the ball after colliding; and rolling and stopping the ball. The detecting of collision of a spinning ball includes: checking whether a segment connecting a center point in a previous position of the ball and a center point in the current position collides with the ground; and generating vectors of a lower part of the ball to check whether the vectors collide with the ground.
