Something for the weekend for you to look at and ponder.

  Photons were used, but there's no resulting 'sparklies'. Probably because 
I used an ior of 1.458 for a quartz effect on the three single barbells. 
(What's with those bright bands on the blue and bright green barbells?)

   The shadows look weird to me too. The blue barbell has a solid shadow, 
and the other two don't. (?)

   Anyway, it took about 8.5 hours to render with +a0.0.

So this is the image you mentioned!

When using photons, all transparent objects throw solid shadows. If the 
photons don't reach through the green barbell, you'll retain the solid 
shadow. How deep did you set the trace_level for the photons? I'm not 
sure if they can get through such complex objects...

+a0.0 with which recursion level and antialiasing method? That's 
important as well, you know... ;-)

Overall, a nice, simple image and clean image. The wood could use some 
more irregularities, and personally I'd like some more dramatic lighting 
effects (a la sparklies, or just a different mood in lighting), but it's 
a nice one. It's a little heavy towards the left side (more objects and 
color differences there), so if you'd switch sides, it could be a good 
backdrop for Windows-Desktops with lots of icons. :-)

Regards,
Tim

      That's the one! :o)

     Just checked: max_trace_level 5

     No, I didn't do a recursion level. Stumped now with this new term...

     This is what I did do though...

   //CODE

  global_settings {
  assumed_gamma 1
  max_trace_level 5
  #if (Photons)
    photons {
      spacing .03
      gather 20, 100
      jitter 1.0
      adc_bailout 1/255
      autostop 100
      radius 100
      // (---Adaptive Search Radius---)
      //steps 1
      expand_thresholds 0.2, 40
    }#end}

  And, LOL! In my interior statement, I DID forget to lower my 
dispersion_samples from playing around before!

    I had it set at 140 for this image.... <sigh, whistles almost 
silently....>   :-o -->>>

   Thank you Tim.

    Heh, that did cross my mind as I had loads of DT icons! (Now cleaned 
up).  :o)
