This package provides a library written in Lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with LuaLaTeX. The definitions and calculations are only done with Lua. The main possibility of programming proposed is oriented “object programming” with object classes like point, line, triangle, circle and now, conic. For the moment, once the calculations are done, it is tkz-euclide or TikZ which allows the drawings.
