Computer graphics programming uses linear algebra so heavily, you could basically say it's based on it. Yet, many people — perhaps most — who develop an interest in graphics programming don't have a background in Linear Algebra. At most universities, it is taught as an upper-level (300 or 400) mathematics course, which means that the majority of students who aren't majoring or minoring in math or certain hard sciences, typically don't take them. Even if you have studied it, if you've gone a period of time without using it, you very likely have forgotten it.
Yet, if you want to go beyond a certain level in graphics programming, you need to understand it.
Today, I stumbled across a free course in Linear Algebra, and it looks to be quite good. It's dense but, hey, this is higher math we're talking about here, so there's not much that can be done to simplify it without making it incorrect. But the price is right, the content is good, and what's even better is that the course doesn't assume much in the way of specific prior knowledge.
Make no bones about it, this is hard stuff to learn, but if you've got a reason to learn it (like a drive to create computer graphics), it helps a lot. Linear algebra in the classroom taught in an abstract manner bored me to tears. Having a real reason and being able to do things with it makes it much more rewarding and fun.
