object 3D

To start, how to draw a new object 3D as asteroid before adding on
Celestia? Thank you to your answers.

For example images of objects 3d.

Unfortunately, your link doesn't work for me.

To display a model in Celestia, you have to create an SSC (Solar System Catalog) file which defines where the object is, how big it is and what model file to use.

e.g.

Code: Select all

"my_asteroid" "Sol" {
   Radius 100
   Mesh "my_asteroid.3ds"
   EllipticalOrbit {
      SemiMajorAxis 3
      Period 5.2
  }
}


There are many additional options you can use to control its appearance, location and orientation. You need to spend some time studying the SSC documentation that's available on the MotherLode at http://celestiamotherlode.net/catalog/d ... ation.html

Also, you probably should read the Web page
http://www.lepp.cornell.edu/~seb/celest ... intro.html
so you understand how Addons should be organized.

That's glad to have message.
It is that, the aspect 3d. The small sphere is not sphere presenting
itself in Celestia. I would like to change it into aspect 3d or a new aspect.

I have just installed the Blender software yesterday. Difficult to
start. Blender can it go for Celestia if not Anim8or, Bryce... ?

Sorry, I write badly in english.

Many people use Blender to make models for Celestia. Export the model to 3DS format. Bryce and Anim8or are OK, too.

To see a sphere, do not use a Mesh.
A Texture makes it look better.

Code: Select all

"my_asteroid" "Sol" {
   Radius 100
   Texture "my_asteroid.jpg"
   EllipticalOrbit {
      SemiMajorAxis 3
      Period 5.2
  }
}
