I have studied the course Computer Graphics and used OpenGL & Qt for my course project. This semester, the course Virtual Reality require us to use OpenSceneGraph.
There are some great works done by some researchers:
And the fantastic works from Siggraph
I was just wondering how did they do these kind of work? What main tools or libraries did they use? Did most of the work based on OpenSceneGraph or VTK?
Moreover, do you know some largest forum for computer graphics? I only know CGTalk, however, this site is for artist I think.
