When I removed the INTERPOLATE=1 keyword, the artifacts
appear to disappear:

vol->SETPROPERTY, data0=volData,ZBUFFER=1,ZERO_OPACITY_SKIP=1, $
OPACITY_TABLE0=(INDGEN(256) / 1);;;;;;;;;;INTERPOLATE=1

This was the first thing I thought of when I saw the
output, because those look like interpolation artifacts
(rounding errors, etc.) to me.

Cheers,

David
