Continuous Dynamic Collision Detection in VR Pool

A new algorithm for continuous dynamic collision detection is developed for VR pool games. The sweep-based 3D physics is applied to the cue ball and object ball movements, which ensures that the fast-moving balls collide with each other. Also, The Time-of Impact algorithms are exploited to compute potential collisions for an object by sweeping its forward trajectory using its current velocity. Experimental results are presented in an immersive and interactive virtual pool environment, showing comparative advantages of accuracy in ball trajectory generations over the existing methods.
