To Scale!

In our last visit to 3-d math land, we moved from the 2x2 and 3x3 matrices we used to learn how matrices function to the full 4x4 matrix that we all know and love to hate from 3d applications. This time I’d like to add support for scaling to our matrices so we can round out the ways matrices work.

Dot Matrix

We started our math review with a look at the dot product, and started out by showing how dots work in a minimalist way. This time out we’ll do the same thing the most basic component of 3d math - the matrix.
