UFO model

Post #1by ElPelado » 04.05.2003, 22:03

i have improved my UFO model. here are some pics of the model orbiting Io(it takes a lot of time to go to earth :cry: so i put it on Io for now).
i still have problems with his orientation.
this is not the final model, i will add a couple of things on the inside, like some controls.

I like it, it looks a lot better. Although I would change the blue color.... seems a bit odd for a UFO

i also wanted to change the colors, i just was trying. but know i am concentrated on the model, not his textures.
what color do you think it would be good?

I think gold would be a better colour.

Have you sorted out its orbit yet?

You could do a lot worse than put it around the main star in the Rosetta Nebula (HIP 500000) using the following settings;

Code: Select all

"UFO" "HIP 500000"
{
   Class "spacecraft"
   Mesh "ufo.3ds"
   Radius 0.060
   EllipticalOrbit {
      Period   0.0000038
      SemiMajorAxis   12500
      Eccentricity 0.0
      Inclination 0.0
   }
   RotationPeriod 0.005
   Orientation [ 90 1 0 0 ]
   Albedo   0.10
}


The craft will receive an eerie red glow, and will offer a good view of the nebula in realtime. I don't know the orientation,3ds name or size you want your UFO so change them to suit.

The only prob is, that not everyone has the nebula and star cluster, so you should offer an alternative solar system orbit as well if you go with this option.

i have to tell you, that was a wonderfull idea!!!!!!!!!!!!
i didnt change the colors, but i put my model with your ssc, and it works grate, you see the ufo iluminated by the red star, and behind you see the nebula. and also trough the windows of the ufo, amazing, i will think about it!
thanks

Another idea is to produce a xyz orbit for it around the solar system. I'm sure this can be done!???

I had a look at a way of doing this by going into celestia and saving different locations at different dates then going out of celestia and opening the 'favorites' file with 'notepad' and viewing the data.
Typical examples below, one for visiting the sun on 1st Feb 2003 and one for Mercury on 1st March 2003;

Code: Select all

"sol1-2-03" {
   isFolder false
   parentFolder ""
   base   [ 0.003261704113563342 -1.622887520913997e-007 -2.821758073579985e-007 ]
   offset [ 2.241956620352426e-013 5.421010862427522e-019 -2.314771638256552e-017 ]
   axis   [ 0.513522 0.835895 -0.19384 ]
   angle  3.50459
   time   2452671.533500259
   selection "#0"
   coordsys "ecliptical"
}

"Mercury1-3-03" {
   isFolder false
   parentFolder ""
   base   [ 0.003263447750326884 -7.271526658535766e-007 6.9089735186409e-006 ]
   offset [ -5.269992341822016e-014 -1.740144486839235e-017 -3.641292996292567e-016 ]
   axis   [ -0.268478 -0.958848 -0.0923576 ]
   angle  2.2382
   time   2452699.534245742
   selection "#0/Mercury"
   coordsys "ecliptical"
}


Unfortunately the time data is the only one that I could use, none of the other figures seem to be useable. Can anyone help as to how to get the correct xyz co-ordinates?

There is supposed to be a way to enter Keplerian elliptical orbital elements into JPL's Horizons server and it'll predict the future path of the object from those initial conditions. I've never tried it, though. Horizons' heliocentric cartesian coordinate system is exactly the same as what Celestia uses.

ElPelado:

That's not what UFOs look like. At least, not the one I was on.
