2D 曲线的作用?
3D曲线这个意思很易理解,但理解2D曲线的表现作用就有点拗口了!
它提到(我把相关的说明贴出来):
Type - ON: A 2D Curve is created / OFF: A 3D Curve is created
A 2D-Curve is defined in the u-v-Parameterspace of the surface. A 2D-Curve yields information of the surface, for example the curvature of the surface. A 2-D Curve does not follow the modification of the surface. If you modify the surface there will be a gap between the 2-D Curve and the surface.
3D-Curve does not yield information of the surface
