NURBS libraries (excluding OCCT)

[A-U]

DA,

I'm trying to assemble a list of open source implementation of NURBS-related algorithms (besides / on top of OCCT). Here is what I have so far:

Ayam - Start

GitHub - ssg-aero/gbs: gbs is a c++ header library to build and manage NURBS, some optional module are used for visualization and export. This library is compatible with OpenCASACADE and has a python biding.

Do you happen to know other examples (preferably under somewhat active development)?

SimplyNURBS implements an ad hoc modeling tool for the prosthetic field. SimplyNURBS is based upon AYAM modeling suite, OpenCASCADE and NURBS++ libraries.

@Quaoar were you able to locate the source of SimplyNURBS? I cannot find it in the paper.

Nope, I actually never tried to find their sources and did not realize they haven't published them.

@A-U Btw, which functionality are you looking for in the NURBS kernel? What's missing in good old CasCade?

I'd like to have better offset surfaces (more robust), better skinning (approximation, constraints) and gordon surfaces. Otherwise just looking around.

Btw, have you tried this SimpleOffset function of OpenCascade? It's the same offsets but with the restriction to keep topology unchanged. I'd say it's not sufficient for general-purpose modeling, but for models with splines it's sometimes useful. I used it to thicken shells composed of spline patchworks.
