Abstract
On account of the dangerousness of coal mining, the remote virtual control of coal-cutting machinery is the development direction of coal mine automation, and collision detection is a crucial technology of virtual reality system. In order to solve the problems about through the wall during virtual scene walkthrough in virtual control of coal-cutting machinery, this paper has researched collision detection algorithm, according to the characteristics of coalface and virtual reality system scene, taking advantage of hierarchical bounding volumes algorithm to solve the collision detection problems of coalface in virtual reality system. And it has compiled the algorithm by applying SDK of Quest3D software. Research results show that, realization of the collision detection algorithm has solved scene roaming simulation degree and the speed of the system in coalface virtual scene walkthrough.
