I extended the PassiveBackground so that it can do something if used within an FBO. This has to be enabled setting PassiveBackground clearFrameBufferObject to true. Than there are two options, either the application sets a callback which gets called if PassiveBackground::clear is called with a FBO active. If the callback is not set the PassiveBackground will blit the window contents (color + stencil + depth) to the active FBO. Currently it assumes that the active FBO size does not exceed the window size (right now it's the first version). I also added an example (Examples/CSM/Shadow/SimplePassive). For me it works, could you check and see if it works for your setup. kind regards gerrit ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
