Don't use this class directly, use the LandscapeMgr. A landscape's most important element is a photo panorama, or at least a polygon that describes the true horizon visible from your observing location. Optional components include:
- A fog texture that is displayed with the Fog [F] command (displayed only if atmosphere is on!).
- A location. It is possible to auto-move to the location when loading.
- Atmospheric conditions: temperature/pressure/extinction coefficients. These influence refraction and extinction.
- Light pollution information (Bortle index)
- A night texture that gets blended over the dimmed daylight panorama. (All landscapes except Polygonal.)
- A polygonal horizon line (required for PolygonalLandscape). If present, defines a measured horizon line, which can be plotted or queried for rise/set predictions.
- You can set a minimum brightness level to prevent too dark landscape. There is a global activation setting (config.ini[landscape]flag_minimal_brightness), a global value (config.ini[landscape]minimal_brightness), and, if config.ini[landscape]flag_landscape_sets_minimal_brightness=true, optional individual values given in landscape.ini[landscape]minimal_brightness are used.

LandscapeId | The directory name of the landscape. |
name | The landscape name as specified in the LandscapeIni (may contain spaces, translatable, UTF8, ...) |
