| // Lookup Tables for Marching Cubes | |
| // | |
| // These tables differ from the original paper (Marching Cubes: A High Resolution 3D Surface Construction Algorithm) | |
| // | |
| // The co-ordinate system has the more convenient properties: | |
| // | |
| // i = cube index [0, 7] | |
| // x = (i & 1) >> 0 | |
| // y = (i & 2) >> 1 |
