I started in 1997 iirc and did not post until 2000-2001. Still I 
remember seeing your name in the posts back then. Welcome back!

I also recall (not that long ago) coming across a graphic where someone used a
spiral arrangement.  I guess that would qualify as a loxodrome?

This was the closest I could find so far.

Serendipity jumps in again with one dark dimple.
I can rotate it out of view but I'll still know it's there.
Place for the logo?

...... obviously possible with icosahedral method. According to these numbers,
there are certain Nsets, and they are

20 Faces
12 Points
30 Edges
164 Dimples
568 Dimples
1190 Dimples

If you need the norms, I got 3 sets.

hm. if you didnt overlap the circles to adjacent triangle,
more Nsets ...??

place inside 28 * 20 + 12 = 572

what's up with 568? cant find any missing.

previous norms relied completely on one command:
/aline -n
doN't list if it's already there.
572 method, would not repeat any points while generating,

According to golf lore -- there are 336 Dimples to a golf ball.

oh right, if they didnt all nestle in right 572, there'd be spaces.
I knew there was reason I didnt try to put them inside.

, just still stumped on the one dark Dimple.
nothing wrong with the norms.
aline -n doesnt fail.

..254043
and
..254042
doh!

dark spot was a tip-off, now it's
162 Dimples
492 Dimples
1002 Dimples

these ought to be known numbers by now.
that was a lot of double points.

not sure if *that's even right, still checking the numbers.
only saw one dark spot out of 76 removed.

could be more

this is 492, I think, doh!

I modeled the golfballs with negative blobs back then, but these are 
modeled with regular polygons. I used an icosahedron for the base and 
added 492 dimples, plus some smoothing here and there to make them more 
perfect.

I almost want to do more configurations. So great that you posted such a
realistically lit scene. People learning, ought to be shown the best examples.
Then there was light ... in colors, o the colors.
Mine had to be nothing less than 9,9 adaptive 1 --per the instructions.
max_trace_level 10 assumed_gamma 1.6 radiosity brightness .8
Took around 30 minutes.
The shadows came out fine I thought. (thread Dimple Details)
Thank you, Anthony
