ocx is a special format of library. Ruby can itself load and use any dll functions, but i´m quite sure it can´t do directly with .ocx files. If you want to use them you must find out the correct dll (and function) to load it and use; the dll should do all the work. So, by default it´s not possible. This requires a good knowledge of Win32API and Windows´s API.
So you have to research and do it yourself or wait until some crazy japanese guy do it for you. I´ve never heard soemone using 3D graphics in RMXP, EVER. Maybe you should add the GL library (a.k.a. OpenGL) into your game (Yes, Ruby has it, but not by default).
Irish what exactly are you wanting to do? Load 3D meshes and show them into a RMXP game? And if so, why? RMXP is a tool supposed to produce 2D games, and anything more than that should lead to an extreme and annoying lag.
EDIT: Your answer may be
here, you just have to find it, decode it into a Ruby code and put it into your game. ^^ For that you may even use the Windows´s dlls or create your own to make the work. Just make sure to know how to use this control.
