Atlases
An atlas is the highest level object in a planetary assembly: an atlas aggregates all other documents that are needed to compose an entire planet. It contains:
- Landmasses,
- Biomes that contain Plants,
- Terrains that contain Soils.
Note that Clouds and Clouds covers are not part of atlases. They can be added over a scene that has an atlas or not.
An atlas also defines the atmosphere layer of a planet.
Creating an atlas
Like all other documents, let's follow the atlas creation procedure:
- Open the atlas document view and click on the create atlas button.
- Open the atlas document by double clicking on it.
We'll see several tabs in the atlas contents. As said earlier there are two main functions covered by atlases:
- Defining a planet's atmosphere.: We'll define the atmospheric parameters of the planet, so this is the look of the sky.
- Defining a planet's contents: We'll define the contents of the planet, this is landmasses, terrains and biomes involved.
Using an atlas
There are two kinds of atlases: atlases that have been compiled and atlas that have NOT been compiled. The compilation of an atlas is a task found in the atlas view toolbar:
An atlas, like most documents, can be dragged into the current scene. It'll become the atlas of the scene. A scene can only have one atlas at a time. When the atlas is set in the current scene:
- If the atlas has not been compiled, this atlas replaces the atmosphere layer of the planet.
- It the atlas has been compiled, this atlas replaces the entire scene and planet (except for Clouds and Clouds covers that remains).
So unless you're working on a planetary assembly, there's no need to compile an atlas. If you do want to work on a planetary assembly, then you'll have to Defining a planet's contents first and then compile the atlas.
