An object will be subdivided into a number of panels.A patch
2、is a four-sided subdivision of a panel that is approximately equilateral. The patches that comprise a panel may differ in size. Patches are the containers for grids.A contour patch is a special elongated patch that lies on an area of high curvature. A contour patch is special in that it does not liv
3、e in a panel. Like a regular patch, a contour patch is a container for grids.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 large, a grid of m-by-n appears
4、 to be sparse. If a patch is relatively small, a grid of m-by-n appears to be dense.) In some cases, m and n are equal.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 contribute to the precision of the NURBS surface.1Patches Shuffle Panels,选择所要编辑的面板,即在所要编辑的面板内任点一点,动作在Define(定义)上类型在Grid(网格)上3、观察面板各边面片的数量,如下图所圈12与16是需要编辑的
