Binary Stars

ah, and i dont understand the billboard thing yet.
billboard is a type of object or a name of a nebula?

The word "billboard" is (American?) English for a large panel (board) that has an advertisement (bill) on it. There are many alongside highways.

I picked the name "billboard" because it describes the intended use of my square 3DS object. So far as I know, there are no real nebulae named "Billboard."

When you define a Nebula in a DSC file for Celestia, you have to give the Nebula a name and you have to specify the name of the 3DS Mesh that Celestia should use to draw the Nebula. Within the 3DS mesh file you have to specify the name of the surface texture picture that should be drawn on the Mesh. Those names don't have to be the same, but it makes it easier to keep track of them if they are the same.

If you want Celestia to show you only one flat picture, then you can use the names that I did. If you want Celestia to show you more than one picture, then each one must be a different Nebula with a different name. Each Nebula definition must use a different Mesh and each Mesh's 3DS file must specify a different surface texture picture file.

In other words, for each different picture (billboard) you'll have to copy the square 3DS mesh file that I created to a new one and give it a new name. Then you must edit that new 3DS file so that it calls for a different picture file.

Does this help?

p.s. That pulsar uses a 3DS model that Rassilon created for use in Celestia. Hopefully his files will be available again soon.

hi again.
1)the star(or nebula or what you call it) Eta Carinae, appears in Celestia???

2)the sirus B star is a dwarf? do you have to stc file for it?

thanks again

[ElPelado]

i have a problem with the Anim8or. when i open one of the meshes that i have on celestia, the program tells me that it cant open the pictures(****.jpg, ****.png ...)
whats the problem?

hi again.

Celestia only comes with the Hipparcos catalog.
Hipparcos did not measure the distance to Eta Car.

2)the sirus B star is a dwarf? do you have to stc file for it?

Someone did create an STC file for it. You'll have to search the Forum. I don't have it readily available.

It's looking in the wrong place for the files.
The easiest fix may be to copy the necessary files either to the Anim8or directory or to the directory containing the model.

[ElPelado]

the problem with the anim8or was solved. thanks.

but i still dont know how to use the program.
i will try reading the tutorial.

[ElPelado]

selden, i make the wheel that is explained on the anim8or tutorial, i saved it mio.3ds.
then i replaced the pod1 model and put my model. but i cant see it in celestia. whats the problem? what can i do, do you know?
this is the code:

"Pod1" "Sol/Jupiter/Io"
{
Class "spacecraft"
Mesh "mio.3ds"
#Mesh "pod1.3ds"
Radius 0.0015
EllipticalOrbit
{
Period 1.7691378
SemiMajorAxis 10540.081
MeanLongitude 219.99989
}
RotationPeriod 0.999
Obliquity 01
Orientation [1 1 1 0]

Albedo 0.3
}

Unfortunately, you already have done more than I have. I really struggled just to get a cube to work!

There are many things that might cause an object not to be visible.

The "Object" menu "Export" item should be used to create the 3DS model file.

A mesh with no surface texture often will be very dim and almost invisible. You might try turning on Wire-Frame mode in Celestia (type a Control-W) to see if it was able to load the object. In wire-frame mode, 3DS objects should look like outlines.

I hope this helps a little.
You now will need to get the help of a real expert, not me. Sorry.

[ElPelado]

YOU ARE NOT AN EXPERT, BUT YOU ARE NOT FAR AWAY FROM BEEING AN EXPERT.
the only problem that i had was that i didnt export the mesh, i put Save As... mio.3ds. that was the problem.
thank you!

[ElPelado]

this my idea for a planet that looks like a star(i have to correct the color of the atmosphere):


and this is a planet that i created(i also made the textures from spec, bump, map and rings) in honor of an argentinian soccer player. its orboting Antares



and another

ElPelado,

Unfortunately, the links to your pictures only work for logged-in Yahoo accounts

[ElPelado]

so you didnt see them?
what can i do?
i have a web on freeservers, but they dont let me put pictures from there, here. i will try to put tha pics on the page

[selden]

I'd suggest that you ask Chris (Celestia's author and the person who runs this Web forum) for Gallery space on http://www.shatters.net.

[ElPelado]

i sent him a pm but he haven'y respond it yet.

and about the adds that i ask for, i already habe them. but there is one thing: do you remember the pulsar that i asked for? i downloaded it, but in the pic there is also a nebula behind it, and i dont have it. do you know something about it?

[selden]

I belive that's Rassilon's "Rosetta Nebula". It can now be downloaded from http://63.224.48.65/~rassilon/
