Homework

I’m always a student ... one way or another. Do you even remember what your teacher taught you over an eon ago? Well last night, I was trying to remember math from high school ... matrix projection (a form of transformation) in a 2 and 3 degree realms. I forgot something as simple as dot products (ring a bell? ... hehe) ... back to the text book. It brings back memories of sleeping in class ... (~_~)zz
