I've just released Geo2D, a Lua library with 100's of functions for 2D computational geometry. The repo also includes a picotron compatible version: https://github.com/eigenbom/lua-geo2d. This cart demonstrates some of the features, like closest point, aabb operations, polygon triangulation, etc. Enjoy!

In 0.1.1d there's no table.sort function. Intended?

I'm on v0.1.1d and noticed this program doesn't draw anything. circfill otoh seems to work okay without a color param.

function _draw()
	cls(0)
	color(7)
	circ(200, 100, 50)
end

Here's a basic raycaster I hacked together. It uses the map editor and renders sprites as walls. It's nothing serious but I've been having fun with picotron during my holiday break.

Here's a simple raytracer for my first picotron cart. Just playing around and runs at about 1fps.

A silly face generator. By me.
