Trying to create my own Trompe-l'œil
/ forced perspective illusionary image to hang on my wall (e.g. the awesome parking garage signage everyone's already seen... more examples here, and here)
. I'm having trouble faking it with 2-D programs, and the math is puzzling me. [more inside]

3D Trig question: I have a 2D square in 3D space (a Face). I know the positions of the four corner vertices in form x,y,z. How do I calculate the rotation in degrees (Euler angles) as relative from the center of the face?
I want to end up with degrees of rotations around x-axis,y-axis,z-axis. Bonus if you can write it in pseudocode.

Vector Geometry Filter: I'm working in matlab and need to transform a surface to match an arbitrary angle. I have the unit vector of the new normal (and the original normal is in the Z axis (0 0 1))...however i'm not sure how to rotate one normal to another (i know, i know, it sounds very simple really...)
