I got no reply on my previous post, so I'll try again.
The following code should in my understanding produce a redish sphere
(attenuation of colors appearing behind the sphere) but no shadow with
media_attenuation off on the light source.
////////////////////
camera {location -z*4.0}
background{color rgb .7}
light_source {<-30, 60, 30> color rgb 1
media_interaction off
media_attenuation off
}
box {<-2,-1.2,-2><2,-1,2> pigment { color rgb 1 } finish{diffuse .9}}
sphere { 0.0, 1 hollow
pigment {rgbt 1}
interior{
media{absorption rgb <0,1,1>}
//media{scattering{1 rgb <1,0,0>*5 extinction 0 }}
}
}
////////////
POV 3.1 seems to respond appropriately, but both MegaPOV and POV 3.5 do
not respond to media_attenuation (or media_interaction for that matter)
with absorption media. Sample pics posted in povray.beta-test.binaries.
Can someone substantiate this?
