摘要
三维虚拟现实漫游技术目前是国内外的研究热点之一。主要研究和探讨了利用五点定位LOD四叉树组织和管理大规模地形数据,并以井地算法实现大规模地形实时渲染,能有效地提升三维场景的渲染速度。提出了一种基于场景投影图矩阵的自动漫游路径生成的钢丝算法,该算法适用于各种复杂的三维虚拟场景并能生成光滑的自动漫游路径。
The 3D virtual reality ramble technique has long been one of the research hotspots in national and international recently. On organize and manage data of large terrain with LOD, and real-time rending the large terrain with arithmetic of ＂JingDi＂ is researched and discussed. The arithmetic can advance rending speed of 3D virtual scene effectively. A method of creating automatic ramble route based on scene projection matrix with the arithmetic of ＂GangSi＂ is presented. The arithmetic can be the same with any complex 3D virtual scene and create smooth auto-ramble route effectively.
