Hi,
you should enquire with them directly first to know if they have a solution or think it is feasible. I fear tho that this will be a lot of trouble because rendering size and anti aliasing will take a lot of processing time, so you would loose the whole "real time" frame rate. Is it acceptable to slow down the framerate to 1 or 2 FPS? it is if the scene is linear, but if there is user interaction....
bye,
