Researching on Simulation of Traffic Accidents Scene by OpenGL

摘要

With the development of automotive industry and transportation, the safety of transportation is huge invisible trouble by bringing great convenience to human being for many years. As result, the reappearance for the simulation of traffic accidents scene is essential. On the other side the reappearance of traffic accidents is not only the method to evaluate the responsibility, analysis the cause, but also to provide the most important materials of prevent and eliminate traffic accidents as possible. OpenGL will be used in this subject which is a graphic library, mainly use on computer graphics and computer image area, especially for computer simulation. Using OpenGL technology to reappearance traffic accidents scene will give the scene of accidents the realest reappearance. This paper proposes researching on reappearance the scene of traffic accidents by OpenGL. In this paper, collision detection (CD) of three dimension (3D) objects will be used. Based on the AABB collision detection, it proposes a new algorithm CAABB collision detection, CAABB will be used on the collision of two objects. There will be two tables to show the difference of using CAABB and without CAABB.
