Hey Art, It’s kind of comforting to hear that you had trouble too – after all I spent a few days on this and couldn’t make any meaningful progress, but then again I’m pretty much a novice at osg(PPU).
So maybe you could help me understand a few things about how osg and osgPPU interact? For example, I am a bit confused about the use of a single camera in the osgppu_viewer example: it’s the same for the render to texture (i.e. osgPPU’s input) and the render to screen (i.e. osgPPU’s output). How does this work? Would it be possible to use one perspective camera for the RTT (as input) and then use an orthographic projection for rendering the UnitOut to the screen? Maybe all connected up as master/slave? (hope this makes sense) Thanks, Christian.
