Abstract: Different algorithms for collision detections (CD) in virtual scene were surveyed. The principle and effectiveness
of axis-aligned bounding boxes (AABB) method, oriented bounding box method (OBB), discrete orientation polytopes
(k-DOP) method and Space-Time Bounding Boxes (STBB)methodwere discussed in detail. The results of analysis prove
that the simpleness of bounding box is in contradiction with the compactness of wrapped object and the k-DOP method is
between AABB method and OBB method in the effectiveness of CD. The main results are useful for designing virtual scene.
Key words: virtual reality; collision detection; algorithm; bounding box
