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. |
