Rectangular Conformal Map

Conformally map a simply-connected open triangle mesh to a rectangle

This code computes the rectangular conformal parameterizations (i.e. angle-preserving mappings onto a rectangle) of triangle meshes with disk topology using the fast method in [1], which has been applied for texture mapping, surface registration, shape analysis and so on. Any comments and suggestions are welcome.

Remarks:
1. Please make sure that the input mesh does not contain any unreferenced vertices/non-manifold vertices/non-manifold edges.
2. Please remove all valence 1 boundary vertices (i.e. vertices with only 1 face attached to them) before running the program.
3. Please make sure that the input triangulations are with anti-clockwise orientation.
4. The output rectangular domain will always have width = 1, while the height depends on the choice of the corners and may not be 1.
