While working out some media stuff for Mike, I ran a a quick media test to just
make sure I had the standard part working, and I got some odd results.
Perhaps someone could render this and tell me why the center gives me a nice x
gradient, but off to the sides I get those weird fans / lines.
(Alain, fyi: the syntax is simply "method 3", not "sampling_method 3")
#version 3.8;
global_settings {assumed_gamma 1.0 }
camera {
location <0, 8, -10>
//location <0, 10, 3>
right x*image_width/image_height
up y
look_at <0, 0, 0>
}
light_source {<0, 50, -1> rgb 1}
sky_sphere {pigment {rgb <1, 1, 1>}}
box {<-10, -1, -5>, <10, 1, 5>
pigment {rgbt 1}

media {
absorption <1, 1, 1>
//emission <1, 0.2, -0.6>*0.9

//extinction 2.0

color_map {

//[0.5 rgb 0.1]
[1.0 rgb 1.0]//center
} // end color_map
} // end density
} // end media
} // end interior
} // end box
