Description
Defines an inclusive altitude interval, in meters, that determines when an object is
rendered based on the camera's altitude relative to a Central Body.
Public Properties
 CentralBody | Gets or sets the Central Body to which the altitude is relative. |
| MaximumAltitude | Gets or sets the maximum altitude, in meters, of the inclusive altitude interval. Use Double.MaxValue to ignore checking the maximum altitude. |
| MinimumAltitude | Gets or sets the minimum altitude, in meters, of the inclusive altitude interval. Use Double.MinValue to ignore checking the minimum altitude. |
Example
