The more general approach is to create a scaling matrix, and then multiply the scaling matrix by the vector of coordinates. Rotate the scaled surface about the x -, y -, and z -axis by 45 degrees clockwise, in order z, then y, then x. The rotation matrix for this transformation is as follows. ( cos ( t) 2 - cos ( t) sin ( t) sin ( t) σ 1 cos ...
