Title: Decoding a Projection Matrix
Post by: JeGX on February 01, 2019, 03:06:45 PM
Most folks who make games are aware of the various transformations that must take place to render convert a 3d model from object or artist space to screen or pixel space.  I think most folks also kind of understand what a projection matrix is.  However, I find that many have trouble explaining what each number in a projection matrix actually means.  The goal of this article is to take away the magic of those numbers and provide clarity with regards to what each number means in a projection matrix.
