Andy Schmeder wrote a bunch of xyz.geometry objects. The new "o.expr" is powerful enough to do these efficiently and John and I have been

pondering what functions to add to the extensive list of basic math favorites. This would be nice to curate while John and I are on your coast. We are trying to schedule that before he takes

the April break from Northeastern....Speaking of Andy: he just told me about a tool that does 3d geometry parametrically but allows you to do convex hulls of objects not points.

It is hard to find this sort of thing that is in a plastic enough form to build into real-time engines for what we want to do but I think it is a valuable direction.

*I want to project various envelopes around real-time 3d models of the space and holes of people's bodies -envelopes that are predictive where the potential is layered over the actual.*

The visual ghostly analog to a sonic pre-echo.

I think this is what basketball players and soccer players (and of course dancers) do. They interact with the ghosts of the past and future.

The present is too late and moving.....

It'd be a very useful learning exercise to clean up this code to calculate the degree of dispersion / clustering of a set of points.
