I love Star Trek, really.. Nice to see others here who do, too.. I haven't
seen the "new" Enterprise yet, but I'm planning to make a realistic looking
Pov spaceship of my own.. I was thinking about, what can be done to increase
realism of textures?
On Earth, a metal texture may feature rust, organic dirt and tiny
scratches.. What would happen if a ship has some organic dirt on it, and
accelerates up through the atmosphere.. Would the dirt burn off completely?
Would it separate from the metal in outer space, due to the cold
temperature? Is it wise at all to have thin glass-like windows on a
spaceship, even with electric shields?

Look around http://spaceflight.nasa.gov (they even have shuttle
specs...I'd like a good POV model of that for scale reference
for building other space things, will probably build my own)

As a heads up, and a note to self that I don't have to reinvent
the wheel, http://hal-pc.org/~jsb/shuttlepov.html already has a
detailed POV space shuttle.

Blah it won't convert to moray, how useless. And it isn't even
built with CSGs, but smooth triangles. Do I have to do everything
myself?!

I think the blue is good the way it is. could you post an examle of
the code for how you aplied the ambient and radiosity?

A good extropolation they did for pre-TOS was the Phoenix in First Contact.
Try taking a look at that and comparing it to the TOS Enterprise.

If you don't have 3.5 I can't help you.
I suggest that you first read the docs about radiosity and then play a bit
with the settings to get a feeling of how it works. You should also take a
look at rad_def.inc
This is just thrown together in a minute, don't expect very good settings.
global_settings {
assumed_gamma 1
radiosity {
pretrace_start 0.04 // start pretrace at this size
pretrace_end 0.02 // end pretrace at this size
count 200 // higher -> higher quality (1..1600)
[35]
nearest_count 5 // higher -> higher quality (1..10) [5]
error_bound 0.1 // higher -> smoother, less accurate [1.8]
recursion_limit 2 // how much interreflections are
calculated (1..5+)
low_error_factor .5 // reduce error_bound during last pretrace
step
gray_threshold 0.0 // increase for weakening colors (0..1)
[0]
minimum_reuse 0.015 // reuse of old radiosity samples [0.015]
brightness 1 // brightness of radiosity effects (0..1)
[1]
adc_bailout 0.01/2 /*
normal on // take surface normals into account [off]
media on // take media into account [off]
save_file "file_name" // save radiosity data
load_file "file_name" // load saved radiosity data
always_sample off // turn sampling in final trace off [on]
max_sample 1.0 // maximum brightness of samples */
}
}
camera{
location <0,5,-4>
sky <0.5,0,1>
direction <0,0,1>
right x*image_width/image_height
up y
angle 60
look_at <0,0,0>}
sphere{<1,1,-1.5>,1
pigment{rgb 1}
finish{ambient 0 diffuse 1}}
plane{y,0
pigment{checker rgb 0.8,1}
finish{diffuse 1 ambient 0}}

yes I have 3.5, thats exactly what I wanted, a working example.
I have been reading about radiosity lately, and doing different things with
it, I just hadn't seen anything like this yet. thanks!!

My only observation from years of trekkism is that rounded hulls=good guys ships,
pointy hulls = bad guys ships.
