Research and Application of Collision Detection Based on Oriented Bounding Box

Collision detection is one of the research emphases in the field of computer simulation or virtual reality,in which the collision detection algorithm based on bounding box is a more convenient and effective way. An Oriented Bounding Box method of calculation was analyzed in order to achieve desired accuracy and real-time property of collision detection in the simulation system,and it was also improved and optimized. Accurate and rapid collision detection of the parts of JQ900 Overhead Launching Gantry with Lower Launching Nose was realized using improved OBB technology,and finally realistic simulation results of the system based on VC++ and Open Inventor API platform were obtained.
