Hi Jeremy, Thanks for the tests and feedback. I'm focusing on creating a material system which may be a little similar to the Ogre one but will be very easy to integrate with OSG scenes. I'd like to also have a benchmark including a complete deferred shading pipeline in the near future to show others how OSG produces realistic worlds. :-)
Your requirement could be easiliy implemented with one forward pass rendering the scene to a texture, and two deferred passes doing the blur work with the texture as input. A final compositing pass will make use of the outputs of the blur passes and output to a new texture. You can get and use the new texture then in the scene for your own purpose instead of direct displaying them on screen. I'd like to upload a DOF effect file and an updated example some days later to demonstrate how these work.
