Well, it took 3 days, but here it is: a basic javascript 3D engine

It's got kinda everything i'll ever need: matrices, pseudo-perspective and orthogonal projections, different render modes(i'm not sure they're called that): points, lines, line chains, line loops, triangle strips, triangles, triangle fans and more.

I haven't optimised anything, so it's pretty slow at times, but mostly 30-60fps (in the gif it's lagging because of the capture software, not the engine).

All in all, i kinda like it
