Collision detection methods for high-speed virtual simulation objects

摘要

In virtual reality simulation, simulated objects under high-speed motion are easy to occur collision detection omission and inaccurate initial point of collision detection at adjacent discrete time point, considering this problem, collision detection methods of functions motion with time are given, which are based on integration of relative motion and space geometrical operation. Relative motion theory is used to reckon movable coordinates transformation matrix functional equation, perform space curve and geometry intersecting test under new motion path, pre-calculate collision time and initial point of collision, finally move and transform this collision point back to system coordinate space and achieve collision position under motion state. This method can effectively and accurately detect the problem of collision under high-speed motion.
