Your vertex array doesn’t match the diagram - for example, the array starts at index 0, so your array’s point 0 at [-1, 0, 0] corresponds to the point labeled 1 in the diagram. It looks like the face definitions use the diagram’s index numbers, but then end up referring to the points from the array which are at different locations.

Got it to render to correctly. Thanks! BTW, your 3D render code is documented really well. Thank you.

I tried the 3D cubes on my Meowbit, and it works great! It gets around 30 fps.
