Interface Summary
Interface	Description
ILcdViewshed	The base interface for all viewsheds.
ILcdViewshedFactory	This interface defines a factory that is capable creating viewsheds for specific domain objects.
ILcdVisibilityComposite	Interface which defines a strategy for compositing visibility values from different viewsheds.

Class Summary
Class	Description

Package com.luciad.tea.viewshed Description

The viewshed package provides support for computing and rendering visbility for 3D scenes consisting of any meshes, extruded shapes or terrain.

The main classes of this package are:

ILcdViewshed: A structure that is capable of determining visibility in a 3D scene for a given observer.
ILcdViewshedFactory: A factory capable of generating ILcdViewshed instances.
ALcdViewshedObserver: An observer for a viewshed.
TLcdViewshedMultilevelRaster: A wrapper around ILcdViewshed that allows it to be visualized.

Viewsheds can also be combined to form composite viewsheds, to expand the functionality of basic viewshed implementations.
