Hi guys, I have what may be a little bit of an unusual question regarding usage of OpenSceneGraph. In our application we use OSG for drawing views of a dynamically created and animated model, which has so far worked out very well for us. We are now in the situation where we would like to be able to interface with various CAD packages and be able to show our model inside them. A number of CAD packages support this by allowing plugins to render OpenGL calls within the host CAD programs viewports (so that the viewport can contain the combined contents of the plugin drawing and elements from the host CAD program). I am wondering if I can somehow use our existing setup for generating these OpenGL calls directly from OSG. Would it somehow be possible to "draw" to a kind of OpenGL call buffer rather than directly to a drawing context from OpenSceneGraph. I guess that there's no code in OSG which can do this directly, but I was thinking that it might be possible to create a substitution for GraphicsWindow32 where I could catch the OpenGL calls being generated, and then transfer them to a plugin in the CAD program from there. I do however see some possible issues where OSG is aware of the exact stage of the OpenGL setup, and I would somehow have to flush this when generating the OpenGL call stack.
Regards, and thanks in advance. Jesper D. Thomsen AnyBody Technology
