You are doing extremely valuable work for educating people on what actually goes on behind the scenes.
The visuals go a long way of visualizing what the code actually does.

It's so nice to explain how to select the correct face of the cubemap by the sample vector. I really need this criternion for point light shadow normal bias determination.

Best explanation I could find for texCUBE function math. Thanks so much

If you construct a full-screen triangle in the vertex shader, you can avoid binding any vertex or index buffers. You only have to find a way to transform the triangle coordinates into world space, but this isn't difficult.
