How does point cloud geometry work in the first place? When you talk about a trillion points, you still have a trillion points being manipulated in data form. There's probably some form of cohesive nature being simulated but how do you define a unique element of the scene? Moreover, are all the points strictly defined, do they behave in a temporary quantum nature, or are they simulated as needed from a series of control points using some method similar to vector fields (or is that too polygon thinking)?
