I've just released luaglut 0.5 at http://lua-users.org/files/wiki_insecure/users/VarolKaptan/ The biggest change since version 0.4 is the fact that memarray, luagl and luaglut now use the OpenGL datatypes (GLdouble, GLint, etc.) instead of the C ones (double, int, etc.). And now we support Lua 5.1 too. Varol Kaptan
