Self.points = list(map(vector3D, points)) Self.object += lor, self.drawstyle, self.data, self.ls So it is really promising but regarding OpenSource it is still science fiction.Ĭode: Select all from pivy import coin, quarter The main issue is that there are no OpenSource mature libs (in closed source you have this one. So it only have advantages regarding CAD. It is also interesting as it allows one to have watertight shapes and to have better continuity between NURBS Patch by easily assuring a given order of continuity by knot insertion. It means that is is easy to make a hole in a part using the same parametrisation. ), you are able to change the topology of the object by adding star points to your mesh. I think that one major advantage of T-Splines is to be able to make a lot of operations (scale,holes, chamfer, fillet. We want to be able to make things evolves using specific constraints and not freely. CAD is about parametrisation, I think that it is the difference with Blender/3DSMax/Rhino. I agree with what you said but I think this is not the important part. So if these kinds of features ( nurbs editing / T-spline editing ) were to be added to FC, I think a mesh editor tool would be best implemented as a general FreeCAD tool that could be re-used by more specific Nurbs / T-Spline / Mesh editors. This is really a mesh editing workflow ( made me think about Blender instantly ).įreehand editing a Nurbs patch is also only about editing a mesh grid.
