I am still weighing up the whether multiple textures or a shared texture would be appropriate. Multiple textures, i.e. one per eye camera would be the most scalable. > So answering your question, Yes, a callback per slave computing each frame > the matrix offsets should be enough. I was using a similar approach. > osg::View::Slave's already have an update callback that can be used to compute the offsets. I'm in the process of writing such a callback to handle standard stereo, but we can probably use this same callback class for multiple cameras. Even if we can't it's still quite lightweight a callback class. The key thing right now is getting the general approach right so that it's easy to add various alternative setups. Robert.
