I had another question I wanted to throw at you guys...
This is the arena I modeled and rendered with POV-Ray.
http://www.wwwmwww.com/TRON/arena.png
It's 100% CSG. And that is where I have my most experience so far. I
posted this image here:
http://www.tron-sector.com/forums/default.aspx?do=top&id=308827&pg=5
and a friend played with it and turned it into this:
http://www.sketchdomain.com/Images/Game_Grid_wwwmwww.png
Which I like the look of alot more. He added 3 basic things:
(1) The image gets darker with distance.
(2) The sky just has color at the horizon.
(3) The red IO towers
I'd like to copy these effects in POV-Ray if I could. #1 I think I could do
with media but I'm afraid it would be very slow and get in the way of
future animations. Any other suggestions?
#2 I think requires a complicated sky sphere. I might be able to get this
effect. It'll just take some tinkering.
#3 Is the one I'm least sure about. Red light emiting media in cones? Just
not sure. Like I've side I've done 99% of my playing with CSGs so far and
I've got a long way to go before I understand just what media can do. Plus
I'd like something that wasn't too slow and what playing I've done with
media so far can be quite slow. Still I'd rather have something that
looked good and was slow over something that didn't look right and was
fast.
Any pointers, tips, or code anyone wants to share?
Thanks,
Carl

Hi Carl,
Nice project you have here.
some tips to create the effects you want:
(1) use fog. Should be in the help file somewhere. It's pretty fast, so
don't worry.
(2) the skysphere is the way to go.
(3) cones with emmitting media like you said. Maybe you need to play around
with cylindrical density to get the disired effect. This may slow down the
rendering. For test renders i suggest using cylinders with finish{ambient 1}
Greetings,
Jan

Thanks Jan,
I now have a shy sphere that looks good:
sky_sphere {
pigment {
gradient y
color_map {
[(1-cos(radians( 90.0)))/2 color 1.2*<238,2,255>/256]
[(1-cos(radians( 90.3)))/2 color 1.1*<3,5,112>/256]
[(1-cos(radians( 91.5)))/2 color Black]
}
scale 2
translate -1
}
}
If I then use a constant fog I get a good looking shy if I multiply the
above colors by the reciprocal of the minimum translucency I use in the
fog. However the fog looks better when I use a ground fog but that reallys
messes up the look of the sky sphere and I'm not finding an easy way to
correct for it. Is there a way to turn the fog effect off just for the shy
sphere? Any other suggestions?
The fog I'm currently testing is this one:
fog {
distance 450
color rgbt<0.0, 0.0, 0.0, 0.1>
fog_type 2
fog_offset 0
fog_alt 10
}
And if it helps here is my current camera:
camera {location <10,31,1> look_at <524,0,440-524> angle 30 right
camera_right}
