   Marching Cubes, Marching tetrahedra 5,6, Centered Cubic Lattice
  Hello,I have to implement MC, MT5, MT6 and CCL. Please help :)   
  Step 1: GoogleStep 2: ProgramStep 3: Ask on forums when you encounter some kind of problem that you require assistance with   ;  We are going to need more details than that! Try to be more specific with what you need help with. Are you having trouble with the marching algorithms in general?, the ambiguous cases? Or (as this is posted on the OpenGL board) with the rendering of the meshes?
