My attempt to use isosurface for 3D snowflakes was not so successful.
But I came up with another solution. I modified my 'Pollock' filter and
used it to 'filter' 2D image. See the source in p.b.s.f.

The image below has the original 2D snowflake #5 from 'snowflakes.inc'
(in the center). The rest snowflakes are just 'filtered' copies of that
original
with different levels of details.

Gena.
