Learn everything you need to know about scaling 3D models with OpenGL mathematics (GLM) in about 10 minutes. In the previous tutorial we looked at how 3x3 matrices can be used to rotate models. This tutorial continues on from there by explaining how scaling can be combined with rotations.
Just as we did last time, we start by using GLM to create our matrices for us, and then we compare those results to our own scaling rotation code that we enter directly inside the vertex shader.
