Class ShapeLineIntersector

java.lang.Object

gov.nasa.worldwindx.examples.lineofsight.LineIntersector

gov.nasa.worldwindx.examples.lineofsight.ShapeLineIntersector

All Implemented Interfaces:

java.lang.Runnable

public class ShapeLineIntersector
extends LineIntersector

Computes the intersections of a collection of lines with collection of Renderables. The lines are specified with a common origin and multiple end positions. For each end position this class computes the intersections of all specified renderables with a line between that position and a reference position. See LineIntersector.setReferencePosition(gov.nasa.worldwind.geom.Position) and setRenderables(Iterable).

doPerformIntersection

protected void doPerformIntersection(Position position)
                              throws java.lang.InterruptedException

Description copied from class: LineIntersector

Called to execute an intersection test for one position.

Specified by:

doPerformIntersection in class LineIntersector

Parameters:

position - the position to test.

hasRenderables

public boolean hasRenderables()

Indicates whether this intersector has renderables specified.

Returns:

true if this intersector has renderables, otherwise false.

Throws:

java.lang.InterruptedException

setRenderables

public void setRenderables(java.lang.Iterable<Renderable> renderables)

Specifies the renderables to intersect with the line.

Parameters:
