The Organization and Schedule Management of Virtual Scene Based on H-B++ Tree

Aimed at the problems of the realization of the virtual scene in virtual reality techniques, the concept of logic control layer is proposed on the base of traditional visual scene simulation systems. The organization and schedule management of virtual scenes are put into the core station to independent of the scene rendering in virtual reality systems. Combined the idea of hash table and B+ tree, a new data structure - H-B++ tree is proposed for the first time. These ideas are used in the development of a launch vehicle simulation training system in this paper. The defects of traditional visual scene simulation programs are avoided by the organization and schedule management of virtual scene via H-B++ tree. At the same time, obvious effects have been achieved
