Hey everybody,

    I was working on an image for a friend of mine who is really into
baseball and i thought "Sure, no problem!  How hard can it be?"  I was going
fine until I got to the baseball.  It seems there is the matter of the seam
and the stitching that goes with it.  The stitching probably won't be too
hard to do once I get the first thing I need:  The equasion for the seam.
Unfortunately, I have only had up to college algebra so I haven't had enough
math to figure out the equasion for a 3D sine wave.  Those machines that
make baseballs have to use an equsion of some sort to follow the stitches!
    Also, is there something similar to a "point" I can use in pov-ray that
would allow me to actually place the seam on the baseball?  Any help would
be greatly appreciated.

Duane

I recently did a baseball picture:

http://www.flash.net/~djconnel/POV/baseball.jpg

I punted on the baseball modeling, using image maps instead of trying
to really do a 3-d job of it.  If you want my image maps, send me
email.... they are modified from an image I got at the Worth
web site.

P.S. My understanding is this group is for actual coding issues with 
the POV source.   I would redirect this discussion to povray.general,
where this sort of thing is more usually discussed.
