Well, here it is, after 2 days, 17 hours, 40 minutes and 34 seconds. It uses
50 samples for the focal blur, besides the photons and the heavy
max_trace_level, and the machine was being used for other things, so I think
that time is justified. This was meant to be a quick test-render for the
final version, but I think it still needs work. It doesn't look much like
the other one. Still needs a lot of tweaking. I think I'll be faking the
focal blur with a post_process, among other things. I was wondering if
anyone can tell me how you would do the pointy triangles of the crown. I
think making it out of a couple thousand (<17k) spheres in a blob {} is a
bad idea, isn't it? :\ Maybe an isosurface can do this just as well, or some
fancy CSG. We'll see. Thanks in advance for all comments and suggestions. :)

Not even really fancy...
difference{
sphere{ < 0,0,0 > 6 }
sphere{ < 0,1,0 > 6 }
#local i=0;
#while( i < 360 )
sphere{ <6,0,0> 3 rotate y*i }
#local i=i+45;
#end
}
Adjust radii and sphere locations to taste.
P.S.: 3 days for a pic this size? Ouch!

I'd have to get out my magnifying glass to see this well enough in this
1400x1050 res. LCD. About 2.7 days huh? Wow, were it not for the better
renders this sort of thing would be pitiful. Sigh.

Well to do the queens crown what I did was to simply CSG difference spheres
from a upside-down cone, while looped in a circle of course. The central
part was refilled with another sphere so that was covered up. Then I added
sphere atop the points. Works fine as seen from a distance, probably not
something to view extremely close.

Just think how long it would take you to paint that by hand with little
brushes...

Probably faster than a 1024 res version, hehe.

I see the thumbnail. Where is the image? Must be a broken link.
Maybe the max_trace_level caused the photons to get lost in there before
coming out. Perhaps, well just maybe, a photon is a really teeny itty bitty
thing so hey, a slow moving photon could get lost in there for days. Two days
and 17 hours and 40 minutes and 34 seconds to be exact. Poor lost photons
....

Wow, more that 2.5 days for this tiny thing?
For the 'crown', you could of course try an isosurface, but i would
suggest a difference between a 'sphere bowl' and several vertical
cylinders. You could also try a parabolid bowl instead of a spherical
one.

Blobs can have negative components you know. Imagine how you'd make a circular
ashtray with CSG, a cylinder with the center taken out, and the a cylinder going
from left to right and one going from front to back, now use the same idea but
as a blob, one cylinder with all others negative, make the cut-out cylinders a
bit short so they don't go over the edge, and you get a nice smooth flowing
object.
I hope some of that made some sence.
I'm going to be doing a chess set for the blind when I've got all my current
"non pov", projects out of the way.
