Hello Billy, There is also the BRL-CAD engine. It is, however, a true solid modelling engine and as such not suitable for direct integration with gmsh. They are working on a BREP representation of their models however. I am not sure what the status is.
Initially I planned on using the BRL raytracer in combination with CGAL to generate a surface mesh. The CGAL people are also working on a volume mesher which accepts piecewise smooth models with multiple regions, which would have been a perfect match. But I don't have time to wait. The OCC approach seemed much nicer once I found out about it. I have learned something I guess ;-) Don't hold your breath for commercial CAD engines to become free. regards, Mark van Doesburg Billy Araujo <[email protected]> wrote: OpenCascade is the ONLY open source CAD kernel that I know of. Of course it would be nice if Parasolid/Spatial were also open source. At least some CAD companies could do like id software does in games which is: exploit a technology commercially and then release old versions as open source. Maybe a 6 year old parasolid version would be better than what is available now.
