Isosurface extraction based on surface nets
Translated from javascript code by Mikola Lysenko, http://0fps.net/2012/07/12/smooth-voxel-terrain-part-2/
All the code is in one single file, without any dependencies. There are two functions, init_surfaceNets, and surfaceNets. The 'main' function shows how to use the code to transform a sphere in a volume into a mesh. The mesh format is:
- first line: number_of_vertices number_of_triangles
- x y z (for vertex 0)
- x y z (for vertex 1, etc)
- a b c (for triangle 0, indices are 0 based)
- a b c (for triangle 1, etc)
This is a render of the resulting mesh:
