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