Abstract: A virtual reality platform for space simulation was developed to simplify the implementation of weapon and based design. First, the architecture of the simulation system was described briefly; Second, based on the characteristics of space simulation platform, several key modules were introduced, including terrain real-time generation, analysis of space layout, and closest distance calculation. The terrain generation for space simulation platform was based on database management. The closest distance calculation was based on nearest neighbor k-d tree searching. In addition, a three-dimensional (3-D) model library, containing vehicles, test equipment, plant facilities, and other tools, was established for dynamic loading and planning. The simulation results show that the virtual reality system is robust, efficient, and realistic, which can meet the requirement of real time simulation of space planning and designing.

Key words: space simulation platform, terrain create, closest distance calculation, nearest neighbor searching
