From i see the guy seem to be hiding the scene from any single even tiny movement at all apart from moving along the camera projection,that's where i think where is the problem is,because when the movement(explosion,deformation,etc) happened it means there is no shortcut for his concept to run the movement of his instanced trilion of point to be simulated into new position?i don't have any phd in math besides my names but let see shall we ,from my opinion this could be good for brand new rendering engine for 3d modeler?.
