This is my attempt at an animation, and not just a rotating object at the
origin.
http://ca.geocities.com/morbjectay/animations.htm
It is split into two files (size limitation on the site)
floor_planA9_a.mpg 3243kb
floor_planA9_b.mpg 3395kb
I used TMPGEnc to combine targa pictures into the animation using
MPEG-1 320x240 24fps CBR 1600kbps
Although most of my time is still spent on adding content to the scene, I
would like to start moving towards better lighting, textures and overall
presentation.
I'm using a single set of splines for the whole animation
(location/look_at). This will be split into several sets covering a shorter
distance. The current path of the camera was only to get started and will
change.
The lighting is Radiosity:
global_settings{
radiosity{
adc_bailout 0.01
brightness 1
count 1200
error_bound .8
gray_threshold 0.0
low_error_factor 0.5
max_sample -1
minimum_reuse 0.015
nearest_count 20
pretrace_end 0.005
pretrace_start 0.16
recursion_limit 1
always_sample on
media off
normal off
} // end radiosity
} // end global_settings
Lighted by (cylinder acting as a florescent tube)
texture
{
pigment
{
color rgb <1.0, 1.0, 1.0>
}
finish
{
ambient 1000.0
diffuse 100.0
}
}
Antialias:
threshold = 0.3
depth = 2
method = 2
Rendered with megapov 1.2.1. I'm not currently using any feature for this,
but would like to add some MechSim at some point in the furture.
Windows 98se says my system is a AMD Athlon XP 2200+ with 224MB ram.
The 800 frames of the animation (320x240) took about 4 days 3 hours. The
longest frame about 23 min and the shortest 2 min.
The roof trusses currently have a little less than half the objects in the
scene and removing them brings the first frame from 12 min to 6 min. I do
like the effect they give the picture so I'll remove them for testing and
put them back in for final renders.

Very nifty! That's what I was trying to do with my castle macros, but
the rendering takes so long for a single image (due primarily to the
lighting) that making an animation turned out to be infeasible.

Thank you. If the animation gets longer than my patience to render it, I may
turn it into a slide show instead :-)

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.
