accessing screen buffer

[hotspur1]

Is it possible to access the OpenGl screen buffer directly within Vizard, or can a plug-in be written to do this? Along with my need for multiple viewpoints, I'd like to be able to get the rendered scene(s) and pipe them to another software program. I need to be able to do this relatively quickly as well. I don't think a screen capture tool like fraps is going to help me in this case...
