Checking out the source code

First checkout and compile the 'Starlab' framework:

git clone

Then check out this repository:

git clone

Then open the file in QtCreator and perform qmake & build

This is a set of plugins for the starlab environment specific to this project. The set contains:

voromat                     generates a medial manifold by projecting a mesh onto the voronoi poles
mcfskel                     mean curvature skeletonization (with medial guidance)
surfacemesh_to_skeleton     a simple plugin to convert contracted meshes into curve-skeletons 
surfacemesh_io_obj          I/O of obj files containing medial information
skeleton_resample           finely resamples a curve-skeleton (used in comparisons)
skeleton_compare            compares euclidean distance between two skeletons


A typical usage is to load the mesh, apply a re-meshing operation, apply the voromat plugin without the embedding option, then start the skeletonization process (MCF steps). The resulting mesh can be collapsed into simple curves by applying the short_ecollapse plugin. The result can be saved to 'cg' file format.
