In this episode I go over textures in OpenGL. There are several different ideas related to textures. Some of the concepts I go over include things like mipmapping, anisotropic filtering, texture sample filtering and more. By the end of this episode, you should be able to create a small field of cubes if you've also completed the past few episodes :)

NOTE: This is super helpful to print out any OpenGL state errors. It catches a lot of simple bugs.
