DrawTrSurf_BSplineSurface Class Reference

This class defines a drawable BSplineSurface. With this class you can draw the control points and the knots of the surface. You can use the general class Surface from DrawTrSurf too, if you just want to sea boundaries and isoparametric curves. More...

## Detailed Description

This class defines a drawable BSplineSurface. With this class you can draw the control points and the knots of the surface. You can use the general class Surface from DrawTrSurf too, if you just want to sea boundaries and isoparametric curves.
