I Just made a classic 3D engine (this is not my first one) but using my algorithm to fill triangles (it's also mine for the 3D projection but it's famous). I really love it but it is completely useless at this time. 100% by me, I used external tools to draw the Icosahedrons. the algorithm to fill the triangle: https://scratch.mit.edu/projects/1243121367/ v1.0: shared as an engine, not a full game
