TetGen Alternatives

    TetGen is described as 'program to generate tetrahedral meshes of any 3D polyhedral domains. TetGen generates exact constrained Delaunay tetrahedralizations, boundary conforming Delaunay meshes, and Voronoi partitions'. There are more than 10 alternatives to TetGen for a variety of platforms, including Windows, Linux, Mac, Android and iPhone. The best alternative is Blender, which is both free and Open Source. Other great apps like TetGen are Wings 3D (Free, Open Source), SALOME (Free, Open Source), Gmsh (Free, Open Source) and MagicaCSG (Free).
