Para-Dice! Nice!

Nice.

Now add focal blur and radiosity and report back the render time difference.
Mwahahahaaaaaa!!!

Nice stuff and the pun is very appropriate indeed :-)

Already done that ... with radiosity 47+ hrs and I didn't like the 
results. I used Radiosity_Fast with pretrace_end 0.004, count 256 and 
gray_threshold 1 /without/ sslt to gather the rad data. It looked pretty 
decent. The 2nd run with gathered rad data and sslt missed the mark :-( 
Is pre-gathered rad data a no-no in this case???

This version /tries/ to try to resolve with a 2nd fill light more 
reasonable render time ~15hrs

Obviously I still have some work to do!

I'm suffering from the recent round of corny-ness in off-topic, and 
couldn't resist ;-)

Very nice, your dice.

I only wonder about the table. It seems to be of marble, a classic material for
SSLT. I suspect that there is no SSLT on it. But I fear this will prolong the
rendering time a bit.

Best regards,
Michael

well I'm calling it a ground plane ... zero thickness box just big 
enough to not see the edges with the camera view. It /does/ look like 
marble but it done as follows:

#declare GroundPlaneMat =
material {
   texture {
   #if (Detail)
     pigment {
     planar
     scale 0.5
     turbulence 1 lambda 3
     color_map {
       [0 srgb <0.9570,0.9570,0.8594>]
       [1 srgb <0.9570,0.9570,0.8594>/2] }
       }
     finish {
       specular 0.15
       roughness 1e-1
       }
     normal{
       planar
       scale 0.5
       turbulence 1 lambda 3
       }
   #else
     pigment { srgb 1 }
   #end
   }
}

the /main/ reason no sslt on ground plane is the scale factor in globals 
used to make dice look good did not suit for the ground plane, and as 
far as I know you can't have two different scales ... btw: used 15. 
Here's the dice material:

#declare DieMaterial_=
#local Color = <0.5500,0.0900,0.0900>;
#local T_val = Color*2.75;

material {
   texture {
     #if (Detail)
       pigment { srgb Color }
       finish {
         specular 0.5
         roughness 1/80
         reflection { 0, srgb Color*0.125 }
         #if ( Subsurface )
           subsurface { translucency srgb T_val }
         #end
         }
     #else
       pigment { srgb 1 }
     #end
     }
   interior {
     ior 2.5
     }
   }

I'm a poet and I know (humbly) it, but all my poor tries of poetry are 
in french.

... was remembering an "old" saying that goes something like:

You're a poet and don't even know it, cause your feet show it. They're 
longfellows.

It is the fortuity, some strange encounter. Maybe am I a poet, maybe you 
are perspicuous and seer, sir.

I think I have the solution! Make the floor a two-triangle mesh. Use the mesh
camera to bake an sslt texture for the ground!

I've been playing around with the mesh camera for my tcrtc entry. It's the best
thing since sliced bread!

Coincidently, this pun is /exactly/ what came across my mind when I read 
the title :-P

Simple procedure to follow for /all/ sslt imagery:

(1) Figure out how large your scene objects are supposed to be in real 
life. Set the scale (mm_per_unit) accordingly.

(2) Do /not/ mess with the scale or the size of your objects from now on.

(3) Tamper with the materials (especially the translucency) until they 
look realistic.
