Attached is a volumetric rendering using media. What is the best way (i.e.
best quality for shortest rendering time) to get rid of the graininess and
get nice, smooth colors?
Any help would be appreciated.
Jim

Code example and version of Pov you are using would be very helpful,
Jim. MegaPov's multi-method media feature can really help smooth out
the graininess and reduce rendering times when used properly but
there are speed vs. quality trade-offs no matter what you do :(

Thanks Ken.
I've attached a copy of the pov and include files. I haven't included the
df3 file since it's rather large.

You might want to consider looking into MegaPOV. The "method 3" of media
seems to work pretty well (quickly, too):

To improve the quality, btw, imcrease the number of samples up. I'd say
samples 3,5 should work for what you're using. Just stick that into all the
media blocks you're using, and the effect should look real nice when you're
done.
Prepare to leave your computer on overnight, though :-/

Ian,
OK. Tried your suggestion with megapov 0.7 The results are attached.
Media looks better except the top and both sides have been chopped off (or
left off). Any ideas what's going wrong or how to fix?
Thanks.

This was using
method 3
intervals 1
samples 3,5
confidence 0.999
variance 1/1000

Here's another result using:
method 3
intervals 20
samples 3,5
confidence 0.999
variance 1/1000
What's going on with this? Looks like the sampling algorithm is not
behaving properly.
