Merging triangles in mesh?


#1

Is there some existing library with functionality for merging triangles (or other faces) with (essentially) the same angles into single polygonal faces (based on GeometryTypes.jl, for example)? Trying to generate line-drawings using Polyhedra.jl, and as far as I can tell, I can only extract triangular meshes (with CDDLib)…?

(I could implement something myself, of course – either for the merging or for simply locating neighbor vertices, etc. :-))


#2

As far as I know, CDDLib exposes the incidence information, which is a polygon mesh, not a triangle mesh.

I was working on getting this incidence information within Julia recently:


#3

Ah, cool. I ended up implementing the thing myself, fusing the triangles from Polyhedra.jl. A bit wasteful, but the polytopes in question are tiny (for figures), anyway. Might rewrite, though!-)
