Example #1

uint8_t MarchingCubes::IndexMirrorZ(const uint8_t index) {
  uint8_t new_index = 0;
  for (int i = 0; i < 8; i++) {

    if (single_index) {
      Vector3 v = corners_as_vectors_[i];
      v.Translate(-0.5f, -0.5f, 0.5f)->MirrorZ()->Translate(0.5f, 0.5f, -0.5f);
      new_index = new_index | (1u << ConvertVectorToCorner(v));
    }
  }
