I am posting this for my coworker, NavyBas, as he is not on the email list yet and he was hoping to get a response before the forums get fixed. He had posted this yesterday.

Hello and thanks in advance for any assistance, 

 First question: What is the simplest way to convert from 2D space to 3D space with OSG? 
 Second question: What is the simplest way to convert from 3D space to 2D (screen) space with OSG? 

 I want to convert a screen coordinate to 3D (world) space, make a couple of 3D matrix rotations, then convert the resulting 3D coordinate back to screen space. 

 Thanks again for your help!
