NVidia released a VisSim demo to showcase NVSG. They showed this demo in the NVidia booth at SIGGRAPH 2007 in San Diego.
Quote from the website: “The demo illustrates the integration of Physics (Bullet physics system), Audio (OpenAL), and Graphics through Producer, Cal3D, FreeType and of course NVSG. Bullet, OpenAL and Producer are all open source projects that are available from their respective repositories on the Internet. Nvidia and the NVSG team do not endorse any of these projects specifically, but they have worked very well for us and we would certainly recommend them. The source code to the VisSim demo is available below.”
