The repo also includes a picotron compatible version: <a href="https://github.com/eigenbom/lua-geo2d"><a href="https://github.com/eigenbom/lua-geo2d">https://github.com/eigenbom/lua-geo2d</a></a>. This cart demonstrates some of the features, like closest point, aabb operations, polygon triangulation, etc. Enjoy!</p> <p>(In browser press 'x' to skip to next demo, or 'z' to reseed the current demo.)</p> https://www.lexaloffle.com/bbs/?tid=146970 https://www.lexaloffle.com/bbs/?tid=146970 Mon, 03 Feb 2025 06:01:45 UTC table.sort <p>In 0.1.1d there's no table.sort function.
