It's one of those thing that is on my "todo list". I will probably implment some simple functions after I get wifi stuff in. Got any request/suggestions? I am not terribly good at 3D graphics, so it probably wouldn't be something too fancy.

I am not an expert in 3D neither, but i assume a few basic things as the following should be enough: create 3D poligons, add textures to faces, move point of view/camera. The rest is up to the LUA application programmers.
You do not need to do fancy LUA stuff, just an access from LUA to existing PA Lib functions. For instance, in the next link you have some basic PA Lib 3D: how to define an untextured 3D cube
