Manhattan surface calculation (left) and a two-dimensional representation of the marching cube surface calculation (middle). With a surface of the red cell 8 using side counting (6.24, marching cubes), blue and green cells 6 (5.12). The marching cubes are shifted at denoted by the black rectangle, i.e., each voxel contributes to four marching cubes in 2D and eight in 3D space. The right side shows a detailed version of one marching cube, determined the surface for the red cell. The edges get the value 1 when it lies inside the red cell, 0 otherwise. The surface then is the 0.5 iso-line
