I'm in a graphics algorithms class and I never took the prereq of ELA. Tell me everything that you know about it. I know some, but not enough. I have a book, but it's tedious and I have other books to read. Specifically right now I need to know how to do cross product and dot products of 3x1 matrices, but I'm sure I'll need more later so tell me everything.
Sure, I'll post everything there is to know about elementary linalg in one post :chuckle: or maybe I won't hehe.
Do you have access to a book? Of course you do. You're in school, therefore there is a library at your disposal. Borrow any elementary linear algebra book and breeze through it. It's actually mostly easy stuff. Even the more abstract vector space theory is easy (but you probably don't need it for graphics). I think for graphics, you're most likely to require knowledge of the rotation matrices and how to apply them to objects in space. It's basic multiplication, so don't worry about it too much.
Actually, if you google Linear Algebra Tutorial, you'll find some good sites to go through. You probably want to understand the theory, and become proficient at computing determinants and multiplying 4x4 matrix multiplications by hand for your exams and stuff.
Don't stress out too much about prerequisites. You KNOW most of the students in your class don't remember anything, so there will almost certainly be some level of review of the material that's necessary for your class.
