The sphere should be solid right up to the edge but I get "Moire Patterns"
instead

Hi there,
I don't know what those lines are but they do not look like moire patterns to
me. I could be wrong, of course, but maybe considering other possibilities might
help you troubleshoot your problem.
Regards,
Dave Blandston

This is the same image file just using a different anti-aliasing (method 3)
always shows up at the edge of the illuminated part of the sphere. Thanks for
the quick response.

Yep, those are moire patterns for sure! I will have to defer to the experts from
this point on...

looks like you did. :-) the last paragraph in section "3.5.1.1.6 Isosurface"
in the 3.8 docs reads:
By default, the inside of an isosurface is defined as the set of all points
inside the contained_by shape where the function values are below the threshold.
New in version 3.8 this can be changed via the polarity keyword. Specifying a
positive setting or on will instead cause function values above the threshold to
be considered inside. Specifying a negative setting or off will give the default
behavior.
regards, jr.

Thanks! Yep, it's new to me. (And I was wondering where those moire patterns
were coming from-- thinking that the planet was just a simple sphere object, not
an isosurface.)
