This one was done with Gilles (most excellent) grass macro. It is very
configurable and all but likes lots of ram (and is a little slow) (6hours on
a PII 450 256 megs +a.3) . I know the area light slows things down but I
would like something a little faster. I know nothing of writing anything
myself so I'm very happy to see something new. Thanks ST :)
I need to put a image map on the ball but haven't got around to that yet.

Slow, but worth it, can be good too.  The jpg compression mucks this up
somewhat but it looks like a nice render.  I've got to complain about the
whites not being white enough though.  That's always a personal viewpoint it
seems anyhow, where I would prefer a very saturated white others might not.
That's why I almost always use a total of rgb 1.5 for lighting or at least a
rgb 1.5 for pigments (total red green blue in various proportions also)
because less never seems to fill the "spectrum" up.

This is a very pleasant picture, something about it is just very "nice."
(Maybe it sub-consciously makes me think about retirement...)

The grass looks great already (more like Astro-turf, in my opinion), but I
do have to agree with Bob about the whites. I wouldn't change much else,
though!

Regards,
Dave

Have you tried Josh English's GrassPatch include file?

Might help.

i think your ball has too many divits.  seriously.  i think there is
actually a standard amount.  i could be mistaken.  nice pic though.

The golf ball Ron Parker made is reasonably accurate -

As I remember, there are actually many different patterns, with 
different numbers of dots, and somtimes with dots of different sizes. 
Also, they aren't just randomly placed, they are always arranged in a 
specific pattern(though not always a simple geometric one). They try to 
get the most lift from the ball as it is flying through the air.

(Note that I have never played golf or designed/studied golfballs, and 
don't plan to, so take this information with a grain of salt.)

Didn't we have a discussion about this sometime in the recent past?
