Hello,
   This is something that may end up being a cgsphere entry sometime in 
the future, if I figure out some texturing and lighting I like.  Any 
comments and feedback is welcome (I'm aware that the dodecahedron is 
protruding from the bottom of its hemisphere.... now.)

   As it is now, its been an interesting refresher lesson for me on 
platonic solids, and the limitations of antialiasing.

   If anyone has any ideas for a faster way to get those gridlines to 
render properly as well, I'm all ears (eyes?).  This render took nearly 
50 hours largely because of the focal blur settings needed to eliminate 
the gridline artifacts.

Nice! Looks interesting even without textures.

Render at 1600x1600 and downscale in gimp or your photo editor of choice? It's
worked for me in the past. You won't need such high aa settings for the rest of
the scene either in that case.

You can slightly broaden the lines and make ther edges a little fuzzy.

Thanks!  That's a good idea.  I think you or someone suggested that to 
me once before for some other scene, but I completely forgot.

That would probably help a lot, thanks for the idea.  I'll have to look 
at the texture from the cgsphere include, I don't want to make it look 
too different.

80 = 20 here:
#declare tiletex =
texture {
    pigment { uv_mapping
      gradient x
      pigment_map{
        [1/20 rgb 0][1/20 gradient y
          colour_map{
            [1/20 rgb 0]
            [1/20 rgb <0.78431, 0.78431, 0.78431>]
          }
        ]
      }
      scale -<1/10,1/20,1>
    }
}

Me too, absolutely!

I just got a minor problem with posting on cgsphere.com...

Since a bit more than a week, I can't reach that site. Are they having problems
or do I have problems?

Have a nice day
Karl
