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, Sphereical Linear Interpolation, and Normalized Linear Interpolation. Continue reading Math Magician – Lerp, Slerp, and Nlerp
