setRotation method

void setRotation(Matrix3 r)

Sets the rotation matrix in this homogeneous transformation matrix.

Implementation

void setRotation(Matrix3 r) {
  final rStorage = r._m3storage;
  _m4storage[0] = rStorage[0];
  _m4storage[1] = rStorage[1];
  _m4storage[2] = rStorage[2];
  _m4storage[4] = rStorage[3];
  _m4storage[5] = rStorage[4];
  _m4storage[6] = rStorage[5];
  _m4storage[8] = rStorage[6];
  _m4storage[9] = rStorage[7];
  _m4storage[10] = rStorage[8];
}
