Research on system architecture of multi-granularity forest simulation system based on component

Simulation of variable spatiotemporal-scale forest growth is a trend in virtual forest simulation field. Most existing virtual forest simulation systems have relatively fixed structure and weak reconstruction capability. Besides, there is much duplication of work between different-granularity forest simulation systems. Therefore, this paper presents component-based forest simulation system architecture so as to achieve rapid construction of multi-granularity forest simulation system. We adopted the component technology to build a loosely coupled architecture, and conducted research on component extraction, classification, design and other key technologies. On this basis, we analyzed characteristics of different-spatiotemporal-scale forest scenes, and achieved the rapid construction of different granularity forest simulation systems through component assembly.
