gptoolbox
Matlab toolbox for Geometry Processing
...It provides a wide range of utility functions for working with triangle and tetrahedral meshes, making it useful for tasks in computer graphics, computational geometry, and 3D modeling. The toolbox includes wrappers for external software such as TetGen, Triangle, QSlim, and meshfix, as well as functions for mesh smoothing, cleanup, deformation, and parameterization. It also implements discrete differential geometry operators, geodesic distance computations, and constructive solid geometry operations. Beyond geometry, gptoolbox includes features for quadratic programming, image colorization, and dithering. ...
