Description
Defines an inclusive distance interval, in
meters, that determines when an object, such as a
primitive, is
rendered based on the
distance, in meters, from the camera to the object.
Public Properties
 MaximumDistance |
Gets or sets the maximum
distance, in meters, of the inclusive distance interval. Use
Double.MaxValue to ignore checking the maximum
distance. |
| MaximumDistanceSquared |
Gets the squared maximum
distance, in meters, of the inclusive distance interval. |
| MinimumDistance |
Gets or sets the minimum
distance, in meters, of the inclusive distance interval. |
| MinimumDistanceSquared |
Gets the squared minimum
distance, in meters, of the inclusive distance interval. |
