Consider drawing a patch, say
patch([0 1 1], [0 0 1], [1 2 3], 1).
I want the patch sides to be of different color: say, "red" when I look at its front-face and "blue" when I look at its back side. Is it possible?
Or maybe it's possible to switch on the "back-face culling" in MATLAB?

I'd also like to know if this is possible.

You need to create your own callback every time the user moves the mouse to rotate, and in that callback you compute what faces are front-facing or back-facing to the camera, and set the corresponding color for each one.
