The computer system, the application related physical effect equipment and the simulator is its the tool using the model to researching the system. The collision detection obtains extensive research in simulation technology and virtual reality , which has the very vital significance。This paper has made a more comprehensive introduction about the collision detection and the three-dimensional space collision detection. A proposal was put forward to the collision efficiency and the reliablity on the foundation. At first, the collision detection algorithm based on the intersection was used. In order to improve the precision and the real-time, the box collision detection has been used. Finally the collision algorithm has been realized. The result shows it improves the speed of detection and reaches the anticipated effect。 Keywords: simulation technology, collision, dete...
