[x3d-public] Procedural collectors, Chaotic collectors

[John Carlson]

Of course, with some of my bubbles,  I am also scaling with something like
lerp.   I’ve forgotten details.

I am not sure if we are talking Newtonian or Quantum collectors at this
point, imagine electrons slurping up photons.   This is where Feynman steps
in.
