About Virtual Reality

[EricSk]

Hi All,
I have a question to VR. I am going to do a project about VR and I want to use the OpenGL API. It seems that many people use VRML to perform their VR stuff. My question is that, what's different between them(VRML versus OpenGL)? And, can OpenGL get more performance?

VRML is fileformat while OpenGL is an API.

In fact, most VRML Viewers use OpenGL to display the VRML files.
