面向森林动态生长过程的场景系统设计和实现

Design and implementation of dynamic-growth forest scene simulation system framework

植物的模拟一直是计算机图形学领域研究的热点问题之一。近年来,国内外的研究人员在提高植物建模的精细度方面开展了大量研究,但是针对大规模植物场景建模的体系结构设计问题,尤其是支持动态生长变化的场景体系结构设计问题的研究还比较少见。针对森林动态生长过程场景系统的仿真应用,提出了一个全新的森林场景架构设计方案,采用了模块化与层次化相结合的思想构建森林场景系统。该系统不仅支持传统方法不能解决的用户动态交互(修改场景实体、漫游)的需求,而且具有良好的维护性和扩展性。

The simulation of plants had been one of the research hotspots in computer graphics area. While great efforts had been made on how to improve the accuracy of plants modeling recently, little research had been published on the design of overall architecture of big-scale plants scene, especially which supports the dynamic growth effect of plants. This paper proposed a completely new framework which adopted the combination of modularization and level-abstraction abstractions of different levels on how to design a forest scene oriented to the above issue. The system not only supports the dynamic user-interactive demands such as run-time modification of scene objects and the user traversing at interactive frame rates, but also has good maintainability and extensibility.
