Remember 10th grade algebra where you learned about vectors and matrices? Remember memorizing the rules for matrix multiplication? You don’t?! Well, that’s good, because neither do I. I vaguely recall having these things presented to me whilst thinking “none of this matters, I’m going to art school.” Like me, you might have pondered many years later how strange it is that these things you thought wouldn’t matter, turn out to be essential to success in your chosen profession. In fact, you might even be stopped in your tracks by the sudden shocking realization that swimming just below the surface of all the modeling software that you use every day are things like linear algebra and calculus. And every once in a while, you will face a problem which stretches the tool too far, With a slightly queasy feeling you’ll realize that you might have to plumb those murky depths for a solution. You might even begin to think, “where did I put that algebra book?” “Why god, why?!” you will shout, “Why didn’t I pay attention?!”

Jeez. Don’t get so upset. Here, have some transforms.
