Convert_ElementarySurfaceToBSplineSurface Class Reference

Root class for algorithms which convert an elementary surface (cylinder, cone, sphere or torus) into a BSpline surface (CylinderToBSplineSurface, ConeToBSplineSurface, SphereToBSplineSurface, TorusToBSplineSurface). These algorithms all work on elementary surfaces from the gp package and compute all the data needed to construct a BSpline surface equivalent to the cylinder, cone, sphere or torus. This data consists of the following: More...
