- - gov.nasa.worldwindx.examples.lineofsight.TerrainLineIntersector

All Implemented Interfaces:

java.lang.Runnable
```
public class TerrainLineIntersector
extends LineIntersector
```
Computes the intersections of a collection of lines with the terrain. The lines are specified with a common origin and multiple end positions. For each end position this class computes the intersections of a line between that position and a reference position. See LineIntersector.setReferencePosition(gov.nasa.worldwind.geom.Position) and LineIntersector.setPositions(Iterable).
