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

A great image, having been away for so long you should also look at the HDR
feature which would add even more realism to this image.

Thanks. You mean using an HDR as a light source? I've thought of it but
never tried. I might use that feature for a future render, since this
one was only a test.

Hi Anthony,
not only that your scene rendered fast as you mentioned, but it also looks very
nice. When looking at it, the colors have different emotional responses.
Interesting. I really like your beautiful scene.
Can you do a large version of it? The only change I would want it to remove
these little star-cutouts, but that is just me. Others mighr like them a lot. I
want to use your scene on my 16:9 desktop as background.
I wonder of the scene would look if all these colored golf balls would be made
from glass and not opaque plastic, wood or ivory. Wanna give a try?
