Collision detection algorithm based on bounding box is an important algorithm of collision detection.The principle and effectiveness of axis-aligned bounding boxes(AABB)method, oriented bounding box method(OBB), discrete orientation polytopes (k-DOP)method were discussed in detail. The results of analysis prove that the simpleness of bounding box is in contradiction with the compactness of wrapped...
Because of the limit of the domestic configuration software which is in the use of scrutinizing the coal mine, the ActiveX technique is discussed and the design of the safety of coal mine, which utilize the ActiveX technique, is actualized. The fig of system frame and the implementation of part of modules are also given. This system can provide the friendly interface for the controlling of coal mine,...
