Approach to Software Component Design of Three-dimension Topographic Map in Forestry

This article puts forward a kind of designing method of O O (Object Oriented) and supported for software component of three-dimension topographic map in forestry, and the capability, designing method, and the algorithm of graphic cell were analyzed. The component design of three-dimension virtue-scenes based on OpenGL, module construction, and movement-simulation have been realized. In this article, the movement-hierarchy link relation of entities and data structure have been described, the constructing modele and movement-simulation of the virtue environment in forestry have also been realized.
