Howdy all I am using OSG for generating synthetic environments for AI agents.
I have two views: one that chases the simulated autonomous vehicle and one that is taken from the simulated vehicle's payload (pan-tilt-zoom camera). I have a third context, a pbuffer, that is assigned to a camera slaved with the pan-tilt-zoom camera, so that I can easily ship the pixelbuffer to CPU space where the AI engine processes the images (according to what the pan-tilt-zoom camera sees). It all works fine when I render terrain that was loaded from a terrapage database (.txp). However the troubles starts when I replace my terrain with a scene generated by osgOcean: I do see the ocean scene in the chase view camera viewer window and also in the pan-tilt-zoom camera viewer window, but when I inspect the images from the slaved off-screen camera that are saved to a jpg on disk, I don't see anything - just the default blue-purple background. Anybody have an idea what might be causing this behaviour? My system: Intel Core i7 CPU Q820, 8GB, Windows 7 (service pack1) NVIDIA Quadro FX 1800M and using latest release version of OSG.
