CSG objects. Made of big sphere in center, small spheres around and differences
(cylinder - torus) to smoothly connect them. Yes, it looks like something similar to
splorks
(http://news.povray.org/povray.binaries.images/30636/), but no blobs were used. (It
seems to me, splorks are made of blobs, am I right?) As usually, if anybody interested
in source, I'll
post it in p.b.s-f.
Sincerely Yours, Alex Kluchikov.

Woah that looks really cool!
What material have you applied to them? it looks sort of like blurred
reflections but I assume it's just a blurry HDR image or something.
Can you animate it? :)

did you use/try the "r_ConnectSpheres" macro from
pov.../scenes/advanced/cats/coolcat.inc ? If not, you seem to have the
same "problem" that I had. The transition from sphere to the difference
{cylinder/torus} object is not 100% smooth. Is it possible at all with
pure CSG?
Anyway, I like the objects, they seem to beg for a checkerd plane ;)

Alex,
Another fine picture, you are talented :) I totally love the texture..
looks very much like silver. How did you make it?

I used big hollow shadowless sphere, about 1000's of POV units large, with
a little colorfull bozo pigment on it - it creates a blurry reflection
illusion, very applicable to smooth metallic surface.
I did not tried to animate this object this is why: I generate some random
values for every small sphere. Not all of them are suitable, so, I need to
throw out some. If animated it would create effect of sudden appearing and
disappearing - so, I decided to put off animation problem untill I have
some ideas.
Sincerely Yours, Alex Kluchikov.

No, I did not use macro from /scenes/advanced/cats/coolcat.inc.
It is pure csg, and we can not get 100% smothness with csg like this - we
have at join line continuous surface, continuous normal vector but
discontinuous derivative of normal - so, we receive smooth surface if no
reflection, but unsmooth if there is reflection. I think, with csg we can
not solve this problem.
And if you really like checkered plane, I can post one (even imagine:
Subject: checkered plane. Attached picture - checkered plane ;) It was
joke...
Sincerely Yours, Alex Kluchikov.

I used something like envionment map - a textured hollow sphere, big enough
to contain all the scene, with no_shadow and no_image attributes set. I
already answered on similar question asked by Tek - see. May be, it would
be better to post sources?
Sincerely Yours, Alex Kluchikov.

Could you post the source for that bozo pigment? it looks really good.

OK. Look in p.b.s.-f. in a few minutes.

Very nice, Alex. I used a similar method to make solder-flow in electronic
devices- a torus subtracted from a cylinder. Check out the attached image. And
once again, very nice image.
Cheers!
