Quadrilatural meshing

[epsi1on]

Hi,
Thanks for this good library, I wanted to ask whether is there any repository or well known method for meshing a 2d region with quadrilaterals instead of triangles?

Thanks

A while back, I looked at some indirect approaches to quad meshing (indirect = converting a triangular mesh to quads):

• gmsh: frontal delaunay quad: advancing front algorithm
• gmsh: blossom quad: perfect matching of dual graph
• MeshKit Jaal: perfect matching of dual graph
• Q-Morph: advancing front algorithm

Gmsh and MeshKit are open source, but the code is hard to look through. MeshKit is really painful to build (never managed to build on Windows). Gmsh has a SDK with C interface and prebuild binaries, but it's probably overkill if you're just looking for a 2D quad mesher.

I also tried to port the MeshKit algorithm to C# for use with Triangle.NET: QuadMesh-2015-09-10.zip. The code works, but it's somewhat unfinished.
