Hi all (and thank you for your help in the past). I work on an application were I'm using OSG to display viewports of a model. I have a function of my application where I use PBO's to take high-res screenshots of the displayed model. However, I now also need to be able to take screenshots from a script-defined camera (a camera in my application, not an OSG-camera) without having a viewport of the model open. That is, I need to be able to render to texture (In my case PBO) even if I'm not using OSG to drive a viewport. But, how do I make an osg viewer without a handle to a window which it should use to display the model? I would also like to use this to enable offscreen rendering in a console application, where I need to output images of a running analysis, which only uses the command line (on a Windows system).
I have looked at the osgprerender and other examples, but they all create a viewer with some window rendering context. Any hints and help would be much appreciated. Regards, Jesper D. Thomsen
