transposeRotation method

void transposeRotation ()

Transposes just the upper 3x3 rotation matrix.

Implementation 

void transposeRotation() {
  double temp;
  temp = _m4storage[1];
  _m4storage[1] = _m4storage[4];
  _m4storage[4] = temp;
  temp = _m4storage[2];
  _m4storage[2] = _m4storage[8];
  _m4storage[8] = temp;
  temp = _m4storage[4];
  _m4storage[4] = _m4storage[1];
  _m4storage[1] = temp;
  temp = _m4storage[6];
  _m4storage[6] = _m4storage[9];
  _m4storage[9] = temp;
  temp = _m4storage[8];
  _m4storage[8] = _m4storage[2];
  _m4storage[2] = temp;
  temp = _m4storage[9];
  _m4storage[9] = _m4storage[6];
  _m4storage[6] = temp;
}
