I am having an extremely hard time understanding smooth 3D collision. I have spent a month trying to figure out the math and still cannot get perfect collision detection that perform the same way as in games such as Quake.
I've resorted to a virtual 2D rectangle collision model applied to 3D plane, but it's full of bugs and doesn't handle slopes. It seems that very complex math is required like matrices and vectors. There are lots of tutorials online but they are full of mathematical symbols and it's impossible for a math novice like me to understand it, I also don't have time to go through a mathematics basics from the beginning. Is it possible to do collision without vectors or matrices or a guide somewhere that can explain in non mathematical terms how to implement smooth collision? How can a nonmathematician overcome 3D math?
