Re: Registering a class that takes a float*

You might be able to use it like that: here's a part of some code that I
wrote that lets you wrap functions that involve OpenSceneGraph types, where
I'm using another library (osgLua) to handle those on the Lua side
primarily. Between this and the documentation, it should be enough to help
you do a similar thing for GLfloat*
