You know what irks me? Going online to look up something simple, like Dot Product or Cross Product, and getting nailed in the face with calculus proofs and discrete mathematics on why this and that happens, but never getting a simplified answer on what I’m looking up!

Well, I have a website, and now it’s time I delivered the simple answers. Open wide for a study guide. Continue reading “Math Magician: Much Ado About 3D Math”

Man, I wish I had this blog going through school, because this place has become my online notebook. Game development is like riding a bike – but math, for me, can have a hard time stickin’. I’ve been working in databases so long that I have a lot of bit-shifting down, but my matrix and vector math is starting to lack. So, a creative way for me to remember all these algorithms is to try to explain them. Today, I’m going through Linear Interpolation, Spherical Linear Interpolation, and Normalized Linear Interpolation.
