Neat
:)
I would like to see this turned into a fully working factory :)
You might wanna turn off radiosity in your renders. It will reduce the
flickering in the animation and speed up the render precess by a couple of
magnitudes

I have tried using lights early on, 50 point lights, but was disappointed
with the shadows this created. A small mount of flickering is acceptable,
but not the current amount. Any suggestions on how to light the interior of
a building like this with lights?

I use a 3-point lighting for the background light.
If sun light can enter the building then it's something like this
// the sun
light_source{ 0 color SunColor * 0.75
#if (Final)
area_light <25000, 0, 0>, <0, 0, 25000>, 7, 7
adaptive 1
#end
translate SunPosition
}
// background light
light_source{ 0 color SunColor * 0.250
translate SunPosition
rotate y * 120 shadowless
}
light_source{ 0 color SunColor * 0.250
translate SunPosition
rotate y * 240 shadowless
}
one or more rows of overhead point lights, emulating the fluoressent tubes,
for the overall inside lights and I would use point lights near the
machines so that the machines are clearly visible

I've been giving this some thought, I may try it later. The building only
has windows on two sides, several walls and shelves of material block large
portions of the interior from direct sunlight. "rows of overhead point
lights, emulating the fluorescent tubes" is the part I'm struggling with.
There are approximately 14 rows of 10, 8 foot double fluorescent tubes, with
most pieces of equipment having one or more additional light fixtures
hanging from the ceiling. Any suggestions on how many point (or maybe spot)
lights per fixture I should use?

Thanks, as time permits I'll experiment. The image is very close to the
style I was thinking of.

This is my attempt at an animation, and not just a rotating object at the
origin.
http://ca.geocities.com/morbjectay/animations.htm
Floorplan_B.mpg 1437kb, 300 frames
Floorplan_F.mpg 487kb, 100 frames
I've reduced the use of radiosity and included a point light at the camera
location.
Comments most welcome.

That is cool, but I almost missed this one. Create new thread?
Can you show how you make your camera move through a path like that?
In my "Tomb", I made several clips and put them together afterwards. Would
be better to make all movement in the same file...

Thanks.
For the camera, I declare some splines first, points going from 0 to 1 with
a point before and after incase I use quadratic.
#declare lookatspline_C =
spline {
quadratic_spline
-0.1 ,< 15700 , 350 , 600 >
0 ,< 16030 , 390 , 600 >
...
#declare locationspline_C =
spline {
quadratic_spline
-0.1 ,< 15700 , 360 , 600 >
0 ,< 16000 , 360 , 600 >
...
For the camera, part of the definition looks like this
#if(clock_on=0)
camera{
... stuff for still picture
#else
camera{
perspective
#ifdef (locationspline_C)
location locationspline_C(clock)
#else
location <0,0,0>
#end
#ifdef (lookatspline_C)
look_at lookatspline_C(clock)
#else
look_at <0,.5,0>
#end
#end
}
light_source {
locationspline_C(clock)
, rgb <.8,.8,.8>
}
I was unhappy with a radiosity only lighting, so I have a light follow along
with the camera.
I started out with one long walk (now removed from website) but decided to
brake it up into smaller shots. This is a long term project for me, as I
slowly improve the scene elements, I'll update portions of the animation.
