Hi,
I'm currently writing a 3dm to osb converter based
on OpenNURBS. I am using the opennurbs_gl.cpp sample
as a basis (it renders a 3dm file directly into OpenGL).
The trickiest part of the conversion are the NURBS. I got
stuck with the trimming and hopefully Akos or Patrik will
have time to look into it. Now I have a different problem.
Rhino of course supports also polylines. In the opennurbs
sample those lines are not mapped into GL_LINES but into
1st degree curves. To do so, it uses calls to
gluBeginCurve(...);
gluNurbsCurve(...);
gluEndCurve(...);
As if it is a trim curve. In OpenSG this would be something like
this:
SurfacePtr surface;
NodePtr ret = makeCoredNode<Surface>(&surface);
beginEditCP(surface);
surface->addCurve(...);
endEditCP(surface);
Unfortunately, I don't see anything in the output osb. My
question is, if this is a "legal" OpenSG surface or if there's
just anything missing.
Regards,
Toni
