Research on collision detection and motion control in virtual environment

According to the problems existed in the collision detection and the motion control in virtual reality, the paper proposes the algorithm of entity object trajectory after further analyzing, improves the calculation method of the direction of bounding box (OBB) so that to achieve the required accuracy of collision detection and real-time nature in simulation system, and illustrates the application in the JQ900-type beam bridging machine in the virtual reality, which enforces the simulation results greatly.
