Sure thing.  It's - rough.  ;)


While coding up some other stuff, I was thinking about how to make isosurfaces
easier and faster to develop.

There must be a way to give feedback on a threshold that the user missed - such
as mistakenly using vlength() as the formula for a sphere rather than vlength()
- r.
I was thinking maybe sampling along a few vectors from the center of the AABB or
from the center of any points found.

That led to the idea of feedback on better bounded_by constraints.  No one ever
renders an isosurface ONCE.   If there's a lot of empty space, then maybe the
algorithm can keep a running tab on min/max extents of the actual object.

And maybe there's a way to take fewer samples when smoothing the gradient, but
interpolate more, in order to have fewer calculations and greater speed when
running prototypes.

BB optimization also would then be a further refinement.  ;)



OK, off to work.
