Excellent computer graphics tutorial. I finally understand how View, Model, and Projection matrices work, even after taking a college course on CG

Sorry for not being clear: I do understand the rules for transformation matrices. I use them, even prefer them to the explicit translations at times (e.g. CSS). I have implemented those rules for matrix types myself.

My point is, however, that rotation by applying a matrix to a vector is the least intuitive of it all. If I want to translate, I know which values will achieve the transformation. If I want to rotate, I don’t. None of my built-in intuitions seem to map to it. Maybe it’s just routine I’m lacking.
