In Episode #3 of Shaders Monthly, we introduce the OpenGL modelview matrix, which allows you to perform 3D transformations, such as translation, scaling, or rotation. We look into the mathematical theory of these transformations and implement the corresponding shaders in GLSL.

The implementation is based on the following example from episode #2:

Here are the links to the resulting shader code:
