I don't know but I hope it's the one with soft reflections on the floor. On
the other one, the blue ball looks flat.

Bryce is the one with soft reflections. I wish I knew of a way of doing that
in POV.

I know. It doesn't seem as good as the Bryce anti-aliasing. Far too chunky.

But it's easy to improve:
+AM2 +A0.15 +R2 -J

Try this:

global_settings { assumed_gamma 1 max_trace_level 3 }
#default { finish { ambient .025 brilliance 1.5 } }

camera { location <0,11,-18> look_at 2*y }
light_source { <-100,100,-100>,13000
 fade_distance 1 fade_power 2
 area_light x*23,y*23,4,4 adaptive 1 circular orient
}

#local Input=texture {
 pigment { rgb .3 }
 finish { reflection .5 }
};

#local Blur_Layers=32;

#declare Blur_Tex=texture { average texture_map {
 #local Count=0;
 #local r_stream=seed(0);
 #while(Count<Blur_Layers)
  [ 1 Input normal { bumps scale 500
   translate 150*rand(r_stream) } ]
  #local Count=Count+1;
 #end
}};


sphere { 5*y,5
 pigment { rgb .9*y }
 finish { specular .2 roughness .005 }
}

plane { y,0 texture { Blur_Tex } }

// .........

    Or, better still :

+am2 +a0.0 -j

patterns that you want to get rid of.. But it will slow down things down.

    PAH! just 'cos it's not noticeable it doesn't mean it's not an
improvement! ;)
    Yeah, I only ever use it for a
final-I'm-gonna-leave-this-going-as-long-as-it-takes-and-absolutely-must-hav
