教程 11 - 设定形状类型将网格拟合成NURBS曲面. ( 命令: _RsMesh2Surf in RhinoResurf for Rhino 4 or 5)

RhinoResurf for Rhino 4 or 5 中的命令 _RsMesh2Surf 帮助用户通过定义网格模型的形状类型来拟合NURBS曲面. 下图（图.1）显示了该命令调用后出现的对话框. 该对话框提供了6种形状类型选项让用户选择:
1. plane : 适合于那些能和平面具有数学上同胚意义的网格形状，例如任何一个非封闭的开曲面都能和平面具有同胚意义，但是一个圆柱面则不属于该类型. (图.8)
2. cylinder: 适合于那些能和圆柱面具有数学上同胚意义的网格形状. (图.13)
3. semi-shpere: 适合于那些能和半球面具有数学上同胚意义的网格形状. (图.11)
4. 4corner: 适合于那些能和平面具有数学上同胚意义并且边界上具有4个尖角类型的网格形状. (图.6)
5. 3corner: 适合于那些能和平面具有数学上同胚意义并且边界上具有3个尖角类型的网格形状. (图.2)

6. 2corner: 适合于那些能和平面具有数学上同胚意义并且边界上具有2个尖角类型的网格形状.(图.4)

对于那些能和平面具有数学上同胚意义并且边界上具有n(n>4)个尖角类型的网格形状,RhinoResurf 则提供了另外一个命令 _RsMesh2StarFace 来实现曲面拟合. (图.15)
