Examples of how to perform line of sight calculations in WorldWind.

Line of sight calculations can use both terrain data and shapes. {@link gov.nasa.worldwindx.examples.lineofsight.LinesOfSight} shows how to find points that have line of sight to a given position. It is also possible to determine the intersection of a shape and an arbitrary line. {@link gov.nasa.worldwindx.examples.lineofsight.AbstractShapeIntersection} is an example of this type of calculation.
