Hi,
maybe this is an ancient (and stupid?) question, but after online search I still
don't find anything useful.
In PovRay, two semitransparent boxes with very different thickness but with same
rgbt values have the same appearance. The absorption/transmission doesn't depend
on box thickness. The same even using "media { absorption rgb <.,.,.> }". This
is a sample code:
box {<-250,0,0><250,500,100>
texture {pigment {rgbt <.6,0,0,0.5>}}
interior {ior 1.5 media { absorption rgb 0.0001*<1,1,1> } }
hollow on
rotate <0,0,0> translate <-250,0,100>}
box {<-250,0,0><250,500,1000>
texture {pigment {rgbt <.6,0,0,0.5>}}
interior {ior 1.5 media { absorption rgb 0.0001*<1,1,1> } }
hollow on
rotate <0,0,0> translate <250,0,100>}
This is not physical. Is there a way to simulate the real thickness dependence
Thank you!
