Hello!
Here is example of cloud shader. Source code for it could be found from
my homepage:
http://www.aetec.ee/fv/vkhomep.nsf/pages/shdrex
(Note: it requires patched version POVMan, which could be downloaded
from my homepage:
http://www.aetec.ee/fv/vkhomep.nsf/pages/povman2
)
Rendering time was 1 min 17 sec for 320x240 non AA on 350Mhz Pentium
(I've cropped it a little bit before posting).
Idea and initial code for shader is taken from book "Advanced RenderMan"
and after little tinkering with it I got this what could be seen below:
