Useful functions for geometry processing, constrainted optimization and image processing.

This is a toolbox of useful matlab functions for geometry processing. There are also tools related to constrainted optimization and image processing. Typically these are utility functions that are not stand alone applications.
Here's an incomplete list of cool features this matlab toolbox contains:

- wrappers for TetGen, Triangle, QSlim, meshfix
- mesh smoothing
- mesh clean up (remove duplicates, remove unreferenced)
- geodesic distances on triangle and tetrahedral meshes
- mesh quantities and queries (normals, discrete gaussian curvature, list boundary edges, topology, angles, dihedral angles etc.)
- mesh deformation (as-rigid-as-possible (ARAP), moving least-squares, etc.)
- mesh parameterization (harmonic, least squares conformal, ARAP, etc.)
- automatic skinning weight computation (bounded biharmonic weights, bone heat)
- 2D triangle mesh from binary image
- Input/Output for many mesh formats (.obj,.off,.stl,.wrl,.ply,.mesh,.node,.ele,.poly,.smf,.bdl,.face)
- discrete differential geometry operators for triangle and tetrahedral meshes (cotangent Laplacian, gradient, divergence)
- quadratic programming, active set solver
- scribble-based image colorization, diffusion curves
- exact (un)signed distance field computation for meshes
- constructive solid geometry operations on meshes, booleans
- accelerated point location in triangle and tetrahedral meshes
- image dithering
- deep matlab function dependency
