"WebbBasically marching cubes places a series of cubes (it "marches" them) into the voxel grid. If a cube straddles the isosurface, the cube is "cut" in one of 15 different ways: Actually the 15th cut is a symmetrical image of the one directly above it (the 10th cut), but that's how the original paper described the possible cuts.

If it is not there create it, otherwise use the index. Now the first trick is to realize, that for every x,y,z you only need 3 possible vertices: down x, down y, down z. lithodora imagesWebbFor marching cubes, the vertices lie along the edges. Each edge is shared by up to 4 cubes. The total number of unique edges in each dim is equal to size+1 because the two end voxels don't share their edges. So if you had nx*ny*nz voxels, you would have (nx+1)* (ny+1)* (nz+1) edges.
