摘要
针对任意视点下的球面多分辨率网格建模与求解困难的情况,提出了屏幕细分自适应算法.该算法将计算限制在与视点相关的可视球面区域,求解得到视点相关的可视球面多分辨率网格,并在PC机上实现了可视球面多分辨率网格的三维表现.
In order to deal with the problem of modeling and solving of multi-resolution mesh of visual sphere, the screen adapting division algorithm is presented. The computation of mesh is limited to the visible part of the sphere. The geometric resolution of visual sphere is multi- resolution depending on the viewing point and the viewing distance. Finally, the 3D multi- resolution meshes are display on PC.
