Thanks, it worked fine with the ios and an appropriate color_map! (See
http://dustyattic.org/pool/orbitals.png for a simple example)
I used the texture below. It didn't look very good with fewer entries in the
color map.
#declare gam = 4;
#declare xray = texture{
pigment {
aoi
color_map {
[0.00 color rgbt <1,1,1,1-pow(0.0,gam)/pow(0.5,gam)> ]
[0.05 color rgbt <1,1,1,1-pow(0.05,gam)/pow(0.5,gam)> ]
[0.10 color rgbt <1,1,1,1-pow(0.10,gam)/pow(0.5,gam)> ]
[0.15 color rgbt <1,1,1,1-pow(0.15,gam)/pow(0.5,gam)> ]
[0.20 color rgbt <1,1,1,1-pow(0.20,gam)/pow(0.5,gam)> ]
[0.25 color rgbt <1,1,1,1-pow(0.25,gam)/pow(0.5,gam)> ]
[0.30 color rgbt <1,1,1,1-pow(0.30,gam)/pow(0.5,gam)> ]
[0.35 color rgbt <1,1,1,1-pow(0.35,gam)/pow(0.5,gam)> ]
[0.40 color rgbt <1,1,1,1-pow(0.40,gam)/pow(0.5,gam)> ]
[0.45 color rgbt <1,1,1,1-pow(0.45,gam)/pow(0.5,gam)> ]
[0.50 color rgbt <1,1,1,1-pow(0.50,gam)/pow(0.5,gam)> ]
[1.00 color rgbt <1,1,1,1> ]
}
}
finish{ ambient 1 }
}
