2、- Definition of Panels, Patches, and GridsA panel is an area of low curvature, demarcated by orange contour lines that trace the highest angularity on a surface. An object will be subdivided into a number of panels. A patch is a four-sided subdivision of a panel that is approximately equilateral. Th

3、e patches that comprise a panel may differ in size. Patches are the containers for grids. A contourpatch is a special elongated patch that lies on an area of high curvature. A contour patch is special in that it does not live in a panel. Like a regular patch, a contour patch is a container for grids

4、. A grid is an m-by-n set of rectangles that is placed into each patch. The values of m and n and the size of the patch contribute to the ultimate density of the grid. (If a patch is relatively 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 14 页 - - - - - - - -

The grid, in turn, contributes to the precision of the ultimate NURBS surface. Therefore, the density of the grid and the size of the patch contrib
