Hi,
Using Steve's and others suggestion of a clear cone and media, I'm
somewhat closer to what I want to achieve, but if you look at the image
where the light crosses the illuminated window, you can see clearly a kind
of dark/black hue or line. It doesn't show so much in the darker areas, so
how do I remove it? Also, I'm getting it wrong where it's supposed to start
fading, can anyone help me with this? I've tried fade_distance in the light
source but can't see any difference between a low setting and a high
setting, ie, I've tried .8 and 3.8.
Thanks for any help.
~Steve~
Here's the code...
light_source { <-10.125, 5.83, 13> colour Yellow * 1.5
area_light <4, 0, 0>, <0, 0, 4>, 4, 4
adaptive 1.5
jitter
fade_distance 3.8
}
#declare Media =
media {
emission .028
intervals 5
samples 1, 10
confidence .9999
variance 1/1000
density{
gradient y
ramp_wave
turbulence 18 //0.3
colour_map{
[0.0 colour <.6, .6, 0.3>]
}
scale <1,1,1>
translate <-10.6, 5.2, 14>
}
}
cone{<0,-7.5,0>20,
<0,1.3,0>.05
pigment{rgb Clear}
interior{media{Media}}
hollow
translate <-10.6, 5.2, 14>
}
