many cones.
Varying thickness of the lines gives the arrangement of flower shapes
the appearance of a lightly-etched sphere. This is actually a flat union
of cones in front of a cylinder.

Wow.  Source for this, and/or the "many cylinders," please.  It may be 
just that I'm dense, but I'm not seeing how you did either of these, and 
they're very impressive.

I'm thinkin' Shay's a math genius :-)
Damn artistic too.
Nice job!!!

You said you were going to do it, and you did it.

   I can see why the IRTC does not hold your interest creatively.

After Paul Bourke's post with the intersecting cyls I am compelled to 
think you are doing something similar.  But I know you are not.  I 
really cannot picture what you are doing! The optical perspective must 
be an apparent thing only, if this is in keeping with your earlier 
ideas? The result is lovely though.  Not just a technical brain tease. 
An optical eye tease as well.  How would a sphere covered with such a 
pattern look? Is the scale right? I grow less and less certain.  And how 
would it be lit to give the surface finish effects?  Yet the pattern 
will not flatten. And how to create such a pattern with 3d cones, 
anyway?  I picture them tumbling.  It does make allusions to 
dimensionality doesn't it.  Like those flatland books.  Explanations of 
the fourth dimension that start by asking you to first imagine only two 
dimensions.

I can't share code here because I get to obsessively perfectionist about
it, but I can tell you that there really is no secret to how this
picture was drawn. I did it the same way you would with a pencil, a
ruler, and a calculator. I just used cylinder or cone sections instead
of the pencil.

Thanks a lot for the "Wow".

hmmm. This isn't the "technical" image I mentioned to Steve. That one
will be somewhat similar but actually shaded. The technical aspect will
be that it will take multiple render passes to acheive.

| I can see why the IRTC does not hold your interest creatively.

More the other way around, but it would have been impolite to put it
that way.lol I'm in good company in that respect looking at the poor
rating of images like your incredible 'oranges' entry. I went back and
looked at that image, and noticed that that your text file contained a
line from the song which inspired it. Doh! I wanted to assure you that
my original reaction to that image in irtc.stills was before reading (
and therefore unprejudiced by ) the text file.

Thank you. Although I started both this and the 'many cylinders' image
before having seen the program about him, my continued interest in this
area is very Vermeer inspired. That program gave me a welcome shove in a
direction towards which I was just starting to lean.

The technical part I described in my reply to Dave Matthews. It really
is just a matter of actual effort rather than any tricks like
intersecting cylinders. The whole thing renders in a few seconds. The
pattern is indeed spherical and cannot be flattened.

Something very bizarre about the fact that a 2D image is somehow *more*
flat when the text file creating it has all the same Zs. I'm going to
create a denser image of the same type and when done have the shape cut
from thin metal and framed with room for a shadow behind it. I'm
fortunate enought to have a laser etcher at my disposal.
