Well the opening pitches have been thrown this year..
I have been trying to find a decent baseball in a current (3.6?) POVRAY
version for ages with not much luck. Someone posted one that was close
back in old posting in p.b.i.
http://news.povray.org/povray.binaries.images/thread/%3C38AFF53B.4A483B33%40stud.ntnu.no%3E/?mtop=12
; however, I didn't see all the source posted and what was posted seemed to
be some other related render (maybe MEga PoV?). Somewhere slse in the
newsgroup someone posted a link to a tutorial describing how to make a
baseball seam but the link is now broken.
Anyway can we pool our resources and make a reasonable baseball the
community can use? I would think we can leave off any logo that involves
an image map for now unless someone is industrious.
Sadly, so far I have the basic drity leather ball in the scene. It seems a
little more speckled than the original I based it on for some reason and
making it a much brighter scene didn't help much.
I imagine blobing could be used to add the raised part at the seems but how
to get the red stitches is beyond me. Here is what I have:
