Hi Javier >>Is there any way to explicitly pass an osg::FrameBufferObject to a Camera, >>so the camera renders into it?
Yes you can use a framebufferobject as a render to texture target, checkout the osgprerender example. If you want to use the result of your render in your main app i.e. read the pixel info for some sort of gpu compute, then you need to use a pbuffer for your main viewer. You set it up something like the following Set pbuffer in the graphics traits (used to create your context) to true Set the viewers renderTargetImplementation to FRAME_BUFFER_OBJECT Attach an image as the cameras color buffer. Now when you render the result will end up in the image and could be saved to disk if you like. Hope that helps Tom PS Checkout my helper viewer class and check for the _renderOffScreen bits http://code.google.com/p/hogbox/source/browse/trunk/src/hogbox/HogBoxViewer.cpp Around line 305 and 357 >
