Hi Jelle and Thomas,
thanks for pointing me to the OCEworkflow document.
My SMESH / GEOM modifications are following along the line of what Fotis
Soutis did (Corba stuff removed), with working NETGEN and Tetgen mesher
Plugins.
I am going to contact Fotis Soutis about my modifications to see if he is
interested in them. I think it would be really great if there would be a
PythonOCC
release based on oce 0.10 and SMESH/GEOM V6.5.0 with Netgen and Tetgen
integration sometimes in the foreseeable future.
Thomas , I cloned into your "tp/oce-0.10-support" branch on github and tried my
software on oce 0.10 wrapped using your interface files (with my SMESH/GEOM
extensions) and it works like a charm ! Gosh, I should have checked the git
repositories before diving into modifying the PythonOCC-0.5 SWIG interfaces.
Well, at least
I learned a lot during that week ;-).
I have a few questions about the SWIG interface files:
- How much time and effort do you think would it take for also updating
the win32 swig interface files ?
- I think the gccxml issue I am having on my Mac really is related to
my gccxml version being 5 years old.
So I don't think a patch about that is necessary. What do you think ?
- I was wondering about the renames in TopoDS_renames.i:
%rename(vertex) TopoDS::Vertex;
%rename(edge) TopoDS::Edge;
...
In the version I used before, I could do TopoDS().Vertex(),
TopoDS().Edge(), etc. What is the rationale behind these changes ?
best,
Mark
