Delaunay Triangulation

stl2pov reads an STL (Standard Triangulation Language) file and outputs a POVray mesh. stl2pov has been tested with STL files generated by Pro/Engineer. BUILDING THE PROGRAM For building on FreeBSD and other systems with the GNU toolset, see the instructions in the file INSTALL. After...

Comparison with ground truth and triangulation provided, with varying amounts of gaussian noise added in train and test data.GUI is in Portuguese, but self-explanatory. English version will be provided soon.

Usage: [mfTutteMap] = TutteMap(mnTriangulation)Maintaining the existing triangulation, this function maps a surface mesh onto a planar unit circle. Tutte's algorithm [1] is used. The simple technique for finding point locations is from [2].'mnTriangulation' is an Nx3 array as returned by...
