Class LinesOfSight

java.lang.Object
  gov.nasa.worldwindx.examples.ApplicationTemplate
      gov.nasa.worldwindx.examples.lineofsight.LinesOfSight

public class LinesOfSight
extends ApplicationTemplate

Computes and displays line-of-sight intersections for terrain and renderables. Uses a Terrain object in order to determine accurate intersections relative to the highest-resolution elevation data associated with a specified globe.

This class uses a TerrainLineIntersector and a ShapeLineIntersector to compute the intersections.

Usage:
Shift-click: Calculate lines of sight for a position.
Ctrl-click: Cancel the running computation.
Alt-click: Re-run the most recent line of sight calculation.
