Calculation and collision detection between objects in every virtual reality system is a very important task. Object has its own movement in each graphical system, while moving, it can be collide with other objects, collide with the environment, obstacles. This paper presents a method of collision detection based on a bounding volume hierarchies (BVHs) technical application oriented bounding box for collision detection of objects in virtual reality. The research results have demonstrated the accuracy and reduce the algorithm complexity, computation time.
