OpenGL 3D Vision is a wrapper for OpenGL games that allows the use of Nvidia 3D Vision with them. It has support for many games, and is very good at what it does. It's created by a user of the name Helifax.
OpenGL 3D Vision actually has all it's own set up steps on their website. Instead of typing it out here, you can go watch them yourself. Helifax explains it all much better than I can.
