ok, what i want is to have a ball bouncing (no problem) while being
illuminated mostly by an overhead spotlight (no problem) in a dusty room
(ie the spotlight beam is visible - PROBLEM). i'm not really sure how
to do this, but maybe someone can help me? =) here's the code i have so
far (rather, most of it... the pertinent part). i'm pretty sure the
"media" part is wrong, but i have no clue what to change it to.
thanx for any assistance
media {
scattering { 1, rgb 0.001 }
}
camera {
location <-15, 10, -40>
angle 30
look_at <0, 2, 0>
}
light_source {
<0, 25, 0>
colour rgb 1.25
spotlight
radius 10
falloff 15
// tightness 1
point_at <0, 0, 0>
area_light
<0, 5, 0>, <0, 0, 5>, 5, 5
jitter
media_attenuation on
media_interaction off
}
light_source {
<-15, 10, -40>
colour rgb 0.25
shadowless
media_interaction off
}
sphere {
<0, 5, 0>, 2
texture {
BallTexture
}
}
plane {
<0, 1, 0>, -Rad
texture {
PlaneTexture
}
}

Take a look at the example scene file in
the docsdemo directoty called atmos1.pov

try raising that scattering value...I find that the higher the value,
the thicker the fog/dust/whatever
and the spotlights need to be set to media_interaction on.
media_interaction off means, simply, that the light doesn't interact
with the media, i.e. no cone of light.

i found that the keyword extinction in the media statment can make a
huge difference.. try:
media {
scattering {1, Gray50 extinction 0.0 }
}
this creates an effect similar to emission, but only where the spotlight
is, which is a good effect.. i used that media in an image of a sword
backlite by a spotlight.
