Just a little apropos to Rune's "Request deform" thread in
povray.general
These kind of transforms of iso-surfaces renders really slowly.

how slowly? - cos i think you have a nice wall paper there (if you can bring
yourself to render it!) and take out a couple of the forground .. errr ...
'cubes'..

Well, then you should try to add radiosity and some crackle pattern with
displace warps in the isosurface function ... if that's not enough then
there's also reflection, photons, media, ... don't stop until speed drops
below 0 PPS ...Errr... ;-)
BTW, removing 'no_shadow' and adding radiosity would really look quite
good IMO.

Thank you.
Yes the foreground cubes are not that interesting.
(I have spotted several more interesting ones in the background.)
It renders at about 1 pixel per second.
I'm sorry to say that for the moment I don't think that I
can stand more iso-surface experimenting. Because it takes me
several eternities to verify every minuscule change in the code.
Regards,
Tor Olav

Hehe... then it would be nice to lay down in it and gaze
up on all the malformed superellipsoids fly by.

I wonder if I will ever get access to a POV-computer that
is fast enough render such a scene ...
Thank you for your comments.

Awwh.
Who wants to donate some money to the Buy Tor a Thunderbird Fund? ;)
