【摘要】 面对场景的庞大数据量,如何以更好的效果和更高的效率表现场景,是景观微机虚拟技术中面临的主要问题。在一定的软硬件环境下,问题的解决取决于场景数据结构与定义在其上的算法的优化。本文采用Virtual Studio开发环境中集成OpenGL与3DMAX的技术路线,在分析3DS文件结构的基础上,讨论了场景数据的读取与组织,提出了场景数据组织的逻辑结构,并实现了其中关键结构的算法。更多还原

【Abstract】 Facing the enormous scene data, How to render the scene with better effect and more efficiently, is the main problem in virtual landscape technology on PC. In a certain software and hardware environment, the solution of the problem depends on the optimizing of scene data structure and the arithmetic, which is defined on scene data structure. The line of technology, which integrates OpenGL and 3DMAX in Virtual Studio development environment, is adopted in this paper, organization and read of scene data are discussed on the basis of the analysis of 3DS file structure, the logic structure of the organization of scene data is addressed, and the arithmetic of the key structure is realized.更多还原
