Hi,
I want to do some buffer read back, e.g. read out z-buffer values or
texture values from fbo render targets. How can I do this?
My idea was to inherit from osg::CameraNode and implement an own
CameraNode. But I can't find out where the rendering is done. When and
where is the rendering of the camera done?
Or can I do it anyway else?
regards,
Oliver
