fun, but what am I learning from this that I don't already know, namely that 3d scenes in OpenGL/Vulkan/D3d are made up of triangles? Haven't I seen this already 1000 times when I select a "wireframe" option on every 3d scene that's ever been around for the past 30 years? Every casual gamer who's ever run unigine heaven knows this. Am I being instructed here about the matrix math that creates the perspective illusion on a 2d plane? Not really. All I'm seeing is a bunch of triangles creating a scene. This is not going to instruct a beginner about the principles of the z-buffer in any way that I can see. That requires linear algebra. Unfortunately. No shortcut.
