Research on Collision Detection Algorithm Based on Z_Buffer

Collision detection is an important technique enhancing virtual environment's reality and immersion. The former collision detection methods computation is complex and it will waste a lot of system computation resource when the scene is large. So it brings forward a kind of collision detection method based on Z_buffer depth value. Making use of the information of transform matrix and Z_buffer depth when the scene is rendered, the method detects and responses quickly when user rambles in scene. Experiment data and testifies the method is simple, quick, and independent of the complexity of scene.
