You're probably unpacking the sample data incorrectly -- have you looked at
the VUnpack function in radiosit.cpp? Attached is the distribution that I
get. Here's the code I'm using:
#declare rad_samples = array[1600] {
<250, 127, 71>,
<116, 109, 251>,
<146, 45, 191>,
// (1596 samples omitted)
<221, 117, 172>
}
global_settings { assumed_gamma 1 }
camera {
orthographic
right 2*x*image_width/image_height up 2*y direction z
location 10*z look_at 0
}
#declare I = 0;
#while (I < 1600)
sphere {
(rad_samples[I] / 255) * <2, 2, 1> - <1, 1, 0>, .005
pigment { rgb 1 }
finish { ambient 1 }
}
#declare I = I + 1;
#end

I forgot to vnormalize that whole vector, but it doesn't change the image by
much (the points only move by about a pixel at most).
