ILineOfSight80

This interface provides properties and methods for determining and providing visual indication of the specific locations in the 3D World that can be seen from a selected position.

	Properties
	HiddenTargets	Gets the positions of targets that are not visible from the observer viewpoint.
	ID	Gets the ID of the object. (Inherited from ITerraExplorerObject80)
	ObjectType	Gets an enum that identifies the type of the object. (Inherited from ITerraExplorerObject80)
	SaveInFlyFile	Gets and sets a Boolean that determines whether the object is saved in the Fly file. (Inherited from ITerraExplorerObject80)
	VisibleTargets	Gets the positions of targets that are visible from the observer viewpoint.
	Methods
	GetClientData	Gets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject80)
	GetParam	Reserved. Currently not used.
	SetClientData	Sets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject80)
	SetParam	Reserved. Currently not used.

HiddenTargets

Gets the positions of targets that are not visible from the observer viewpoint. A safe array that contains triplets of doubles is returned, where each triplet is composed of an x-coordinate, a height, and a y-coordinate (XHY order). The height is represented in meters and the x- and y-coordinates are represented in the coordinate system’s units. You can use the ITerrain80 interface to retrieve information about the coordinate system units.

Note: In JavaScript, use the VBArray object. E.g.,

var waypoints = route.Waypoints.ToArray()

var arr = new VBArray(waypoints).toArray();
