Research and Application for Collision Detection Algorithm in Virtools

Collision detection is an important part of the development in virtual reality system. In this paper, we describe the principle, realization of AABB (axis-aligned bounding boxes) collision detection algorithm and three-dimensional frame (3D Frame) collision detection algorithm. AABB bounding box algorithm is a small amount of testing speed. Three-dimensional frame collision detection method is calculating the distance between rays to determine whether the objects collide in a certain time slice. Both methods can handle different situations of collision detection. The paper also gives the application using the Virtool's graphical development engine, two algorithms to solve the collision detection in drilling simulation system. Finally, the whole system can be found to achieve the desired effect of the collision, and collisions are also able to control the accuracy within the system to meet the requirements of authenticity.
