This code computes the spherical conformal parameterizations (i.e. angle-preserving mappings onto the unit sphere) of genus-0 closed triangle meshes using the linear method in [1], which has been applied for human brain mapping, texture mapping, surface registration, cardiac mapping and so on. Any comments and suggestions are welcome.
If you use this code in your own work, please cite the following paper:

SIAM Journal on Imaging Sciences, vol. 8, no. 1, pp. 67-94, 2015.
Remark:
1. Please make sure that the input mesh is a manifold mesh with spherical topology. The existence of holes or non-manifold vertices/edges may affect the computation.
2. While our method focuses on spherical conformal parameterizations, it can be extended for further reducing the area distortion without affecting the conformality (see demo_extension.m and the codes in the directory /extension).
