Thanks for input. I believe that I looked at this paper, when I browsed
siggraph materials at ACM site. I've seen other papers there as well,
which use various approaches for cloud rendering. Perhaps if I have more
time, then I'll try them. But this attempt is based on Katsu's (Katsuaki
Hiramitsu's) approach. At least I believe that it is similar technique,
for he doesn't want to publish shader for this stunning picture (
http://www.edit.ne.jp/~katsu/image/cloud.jpg ), but he was kind enough
to give some hints about used method. So, time providing, I try to hack
it further to get more pleasing results.
