Hi,
I finally finished my reflecting crystals image. Thanks to all those who
replied to my earlier post about my reflection problem. As you can see from
this image I got it fixed. Just eight coloured,metalic, geometric shapes
surrounding a refracting/reflecting crystal with a coloured base. Comments?
Questions? Post 'em here, and I'll do what I can about them.

The central crystal looks truly gorgeous. But the outer shapes are too
monotonous where no light hits them. Perhaps just a bit of fill lighting...
The caustics are... funky?

The colors make this image truly beautiful.
(of course, I like the caustics too... but that's a given for me. ;-) )

I agree with Nathan. This image has great color and balance. Well done!

Good image.. Neat colours.
Settings, rendertime?
Well, SOMONE, do the Discoball, ok?

Really nice, I've been looking at this for ages.
Is the floor totally black, and the colour coming from reflections? And
how long does this take to render? Can you make a 600x800 version and
post it so that I can use it as my wallpaper?
Cheers

Awesome!
What I really like is the circular color spectrum (?) all around the
crystals....
to bad it is cutten on the top and bottom of the image... why dont you try
to render another version with some symetrical settings, such as
+w640 +h640 ?

Hi,
>But the outer shapes are too
>monotonous where no light hits them. Perhaps just a bit of fill lighting...
I want to try and keep the number of lights low or else the reflected
caustics become a bit too hard to see (inside the circle anyway) - there is
only one at the moment. I had been thinking of changing the outer crystals.
They look dark because they have a low diffuse setting, and are reflecting
only blackness around them. As you can see from the image, the central
crystal has many more facets than the outside ones. I was thinking of
changing the outer crystals to the more faceted style. This would give more
phong hi-lights from the overhead lights, but would also make many small
patches of reflective caustics. Would this harm the image? I might do a test
and post the results.
I'm glad you liked the central crystal. I modeled it from a little pewter
statue of a dragon that my sister has. The dragon is holding a small crystal
in one of it's claws. There is a little piece of reflecting rainbow coloured
foil under the crystal, and when you look at it, the colours you see seem to
change. I used the same trick here. As you look from 90 degrees to 0 degrees
along the crystal in my scene, the colours shift from red, orange, yellow,
green, blue, indigo to violet. In the model my sister has though, yo can see
about three or four different colours at any one time - the glass they used
must have a lower ior value than I used (1.463). I might change that too.
Thanks again for your praise and comments!

Hi,
>The colors make this image truly beautiful.
All thanks to mother Nature!
>(of course, I like the caustics too... but that's a given for me. ;-) )
I think we all like the caustics. It's a fantastic patch - thank you so
much! I remember when you started working on the patch first that you said
you would try to implement a new radiosity engine. How is that going?

Hi,
>Good image.. Neat colours.
Thanks!
>Settings, rendertime?
Ok, in global settings I had:
photons
gather 20, 100
radius 0.1, 1 //[, <step size>]
//[jitter <jitter amount>]
//[autostop <angle>]
}
For the central crystal I had:
photons {density .02
refraction on
reflection on
ignore_photons
//photons_pass_through
}
And for the outer crystals I had:
photons {density .02
reflection on
ignore_photons
//photons_pass_through
}
Some Render Statistics:
Number of Photons Shot: 1786260
Number of Photons stored: 1584213
Peak Memory Used: 74.417793 megs
Parse Time: 0h 11m 52s
Trace Time: 3h 20m 41s
Total Time: 3h 32m 33s
My machine is a 450MHz Pentium II, 128 megs of RAM. The thing that took
about 90% of that render time was the central crystal.
>Well, SOMONE, do the Discoball, ok?
I've never actually seen one of those up close - how do they work? Is it
just a reflective metal geometric shape that reflects lights to create thos
spots, or are some of the facets transparent, and let light out from the
inside? If I get enough animation, I'll do an animation of a disco ball, it
ought to be fun. I'll make a square room with four coloured spotlights to
reflect light.
Vote NOW for your four favourite colours! I'll check the votes next
Wednesday (March 24th) at 1830 GMT, and start rendering the animation that
evening. Also what resolution and file type? 320x240? Mov, Mpg, Avi?

Hi,
+AD4-Really nice, I've been looking at this for ages.
Thanks. I thought it might make a nice test for reflective caustics.
+AD4-Is the floor totally black, and the colour coming from reflections?
No the floor is a sort of off-white, beige colour - like in the middle of
the circle. There is only one light, an overhead spotlight that just about
encompases the crystals. The floor is totally black outside the circle
because I gave it an ambient value of 0.0 in the finish settings for that
texture. All the patches of colour on the ground come from reflective
caustics
+AD4-And
+AD4-how long does this take to render?
It took about three and a half hours. See my reply to Spider's post for a
more detailed breakdown of the render time.
+AD4-Can you make a 600x800 version and
+AD4-post it so that I can use it as my wallpaper?
I'll render it at the week end, and post it then sometime too. Your best bet
would be to check back on Monday.

Hi,
+AD4-I second that, this image does say +ACI-Animation,.... Animation+ACEAIg-.
I actually had some ideas for animation. I was thinking of making the
outside crystals rotate through 360 degrees, so as to create shifting
caustic patterns on the floor. Should I rotate them all the same direction,
or have every second one rotate in the opposite direction? And what should I
do with the middle crystal? It has the feature that it's colours change
depending on the angle you look at it from - at right angles or parallel to
the ground. If I was to take advantage of this though, I would have to make
the camera move in the animation, which would make it more difficult to loop
(and it's the kind of scene that would need looping to look best). I could
rotate the central crystal on different axises (what is the plural of
axis?), but that would show up the half sphere I used to get the different
colours, and it looks ugly+ACE-
I want to hear people's oppinions on what I should do.

Yeah, that turned out really nice, I like it myself.

Great idea! Roll on version 2...

Just a ball with rectangular little mirrors glued on is about all they
are. They achieve their "boogie" effect via colored spotlights aimed at
it from various locations around the room which go on and off to the
music. No big deal at all.
I hated disco and always will I suppose. Sometimes I can actually listen
to the music though because of an affliction called "love of music".
Colors to use? I vote for Sasy Red, Moody Blue, Vibrant Green and Mellow
Yellow (Cool Pink too if five colors).
Btw, anyone else think this resembles X-ray spectrograms of crystalline
structures?

I was thinking that it looked more like what a roulette wheel would
look like to someone on LSD. I think maybe I'm having flashbacks.
Whoa dude ! Did you see that ?

Check the camera angle as well, or it'll be distorted..
