The attached images show a simple coloured scene with the default
POV3.1g settings for ambience values of 0.5, 0.999, 1.0, 1.001, & 1.5.
Why the very abrupt white-out for an ambience of 1.0 as compared to
+/- 0.1% from 1.0?
Martin.
The code is:
camera {location <-1,3,-3> look_at 0 translate 0.5*<-1,0,-1>}
light_source{<0,9,-18> rgb<0,0,1>*0.75}
light_source{<0,27,-18> rgb<0,1,0>*0.75 rotate 30*y }
light_source{<0,27,-18> rgb<1,0,0>*0.75 rotate -30*y }
difference{
union{
plane{y, 0}
sphere{<2,0,3>, 0.5}
sphere{<-2.5,0.5,4.5>, 0.5 scale <1,0.5,1>}
box{0.5, -0.5 translate <-2,0,1>}
cylinder{0, y, 0.5}
cone{0, 0.5, y, 0 translate <0,0,-2>}
}
box{0.5, -0.5 scale<1,5,1> translate <-2,0,-1>}
cone{0, 0.5, -y, 0 translate <2,0.001,0>}
texture{
pigment{ colour rgb 1 }
finish {ambient 0.5 diffuse 0.5} // <--- ambient changed here!
}
}

DEFINALTY looks like a bug. For a sec there I was wondering why there
where only 4 images attached, with such a large space between the 2nd and
3rd.. 8-P
