An Approach to 3D Physical Simulated Experiment Based on Physics Engine

In view of the limitations of the traditional physical experimental teaching. A new idea and method to realize 3D physical simulated experiment with the technology of physics engine and real time hardware graphic rendering is proposed,in this paper. In addition,in the basis of Nvidia Physx physics engine,a system of 3D physical simulated experiment which combined the graphics rendering interface of DirectX with interface frame of object-oriented is constructed. And this paper designs a virtual free-fall experiment based on physics engine. Finally,the simulation experiment results show that the commonality and feasibility of this method is proved,and the reality and interactivity of the physical simulated experiment is improved greatly,and the level of teaching and teaching quality is raised effectively.The simulation results can reproduce the true falling of objects,as well as all the process of collision.
