WebbFor 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. This can be pre-allocated as an array.
