I've added some new elements to this WIP.  Sorry for blacking out the coins
on the lower left - I don't own the symbol used there and would rather not
post it. (The sketch isn't mine either, but hopefully those who recognize
it will see it as a tribute).  I intend to eventually create the
environment (inside an observatory) based on input to my last post, but for
now I've stuck with Jaime Vives Piqueres's office (thanks Jaime!).

Inputs appreciated!

Mike

Burninating peasants!!!

Hey, is your ambient on your paper a little too high? The planets look like
they're floating a little becuase the shadow isn't dark enough where they
touch the paper.

Looks great otherwise.

Finish settings:

  finish {           // (---surface finish---)
    ambient 0.00
    diffuse 0.44
    specular 0.0     // shiny
    reflection 0
  }

However, I agree that the shadow looks too uniform and should be darker
under the planets.  I have radiosity brightness level set to 1.  Do you
think that's too high?  The entire image looked a little washed-out
originally, so I post-processed it (gasp!) to increase the contrast.
Anyone have suggestions on how to fix this in POVRay?

OOPS!  I posted the wrong image.  Can someone who has the power to please
delete the previous post and replace it with this one?

Thanks!

Mike

that person is you :) there should be some kind of "cancel message" in most
news readers. not sure about the web interface though.

Yep, I'm on the web interface, and I don't see any options for it.  Well,
maybe one of the TAG members can fix it.

I'm far from the expert, I normally just play with stuff until it looks
right. But you *should* be able to get the brightness and contrast you want
without resorting to post processing. I would try to balance the radiosity
brightness with the strength of your light source (environment image or
point lights). Are you using MegaPOV with HDR, or standard Pov?

Lowering the error_bound should take care of the bland-looking shadows.
Values below 0.5 are generally needed to avoid that ray-traced look.  I
seldom go much lower than that, but i've seen code (written by POVers with
more patience than i) with error_bound 0.1 or even less.  Unfortunately, a
low error_bound also tends to introduce artifacts.  Decreasing pretrace_end
and increasing count can help smooth them out.
