Hi,
this is another entry for Tim Gould’s Disco Remix Challenge:
http://news.lugnet.com/cad/ray/?n=2685
The title 55 Disco was named so because there are 55 lights in this scene. I
know, I went a little crazy. The scene took about 12 hours to render for
1024x768, aa 0.3, q10.
The .mpd file Tim provided has not been altered in any way. I really wanted to
have the light in the garbage can behind the bar show a transparent lego-stud on
the wall, but no matter what I did it was backwards. I could not figure out how
to rotate it at that spot. I really like Andreas’ use of the meshenhancer and
will definitely try that out next time for any “harsh” pieces.
The spotlights aimed at the disco ball was where I originally started. I
couldn’t get them to do what I wanted. I tried photons. I tried photons aimed
at an invisible polyhedron. I tried media. Nothing worked. Then when Andreas
came out with his excellent use of the spot lights I decided to let that area go
and work on the other areas I started.
The bar shelf has three rows of lights. The top row lights and the mid row
lights are placed in the transparent object. The bottom row lights are placed
behind the objects. All of the lights have a low fade distance and an
exponential fade power to give the room a more glowy, darker effect. I would
have liked the top row drinks to show caustics on the walls, but I could not get
photons to work due to the way the translator created a highly CSG’d model....in
other words I kept getting a slab error - nothing to shoot photons at, and
believe me when I tried everything including tearing apart the .pov and
judicious use of “photons { collect off }.” Oh well, another time.
The DJ light was actually an accident. Originally I tried to place it so that
the DJ was completely lit up and had a nice wall shadow, but what you see is
what I started with, and I liked the weirdness of it. I also liked the green it
made.
The floor is probably the best part of my entry. It is the bulk of the lights
(all are point lights with low fade distance and exponential fade power) for the
scene. There is a scattering media on the dance floor as well. Originally, the
lights were in the middle of each color block, but the media and lights created
a horrible line artifact as the light was “escaping” through the cracks. So, I
had to change it to the pattern you see, but it turned out nicely. The effect
was complete when I put point lights in the DJ’s speakers that shine out into
the media.
Finally ambient was turned down to 0.1 and diffuse was turned up to 0.6 to give
the room a more light oriented, darker feel. If I had the will to do another 12
hour rendering I would probably turn the ambient up to 0.25, but this is good, I
think.

Hope you enjoy!
p.s. Oh yeah, the only post-processing was taking out a bunch of black dots. I
had to increase the maxtracelevel to 8 due to the high reflectivity but it
still left black dots.
