I'd like to render to a texture only, not to the screen. The computer (PC or unix) may not have a graphics card. Is this possible with OSG, or even OpenGL in general? - If so, how do I render once my scene and texture camera is setup, assuming I cannot use viewer's setSceneData/realize/frame calls? - If not, and I plug a graphics card in, can I render to multiple textures at the same time, one per user thread? i.e. is the library thread safe? thanks for the help
