Use the arrow keys to rotate the gem. This is a simple 3D gem I made, because I think it will be useful for me to use in games, but anyone can make use of it. I would recommend turning it into costumes though. Despite being simple, it took a lot of lists, and there are 56 polygons making this shape, which is a lot for me. My 3D cube with shading has 24 polygons, which is not much, but quite a bit for me, but this one seems a lot slower for some reason. This is slow on scratch, but it works fine on phosphorus: http://phosphorus.github.io/app.html?id=125102161&turbo=true&full-screen=true&scratch.mit.edu Thanks to my dad, he gave me the maths to do shading, and I will ask him how to change my code a bit, so I can change where the light source comes from. Also thanks a lot to @DadOfMrLog for the triangle filler code.
