I have a scatter points vector field I'm passing through AutoGrid, and
I thought I'd ask about the performance I'm seeing.
AutoGrid: Parms Time Grid Size
-------- -------- ----------
density=.1 1 sec 4x 6x 4
density=.2 4 sec 7x10x 6
density=.4 27 sec 12x19x11
density=.8 4 min 24x38x21 <- still humorously low-res...
density=2 >30 min 58x93x51 <- ...argh!
...
density=.8 & 2 sec 24x38x21
nearest=inf
density=2 & 2 sec 58x93x51
nearest=inf
density=4 3 sec 116x185x102
nearest=inf
BTW, there are only 33404 vectors in this field.
What exactly does this module conceptually do w/ and w/o nearest=infinity?
Given the times and other evidence, my intuition has to be wrong. And the
Autogrid docs and DX results don't seem to agree here.
Thanks,
Randy
