Interface implemented by an object that represents a clutter geometry plugin.

This interface is implemented by the clutter geometry plugin. The clutter geometry plugin is responsible for creating a collection of %IAgStkRadarClutterPatch:AgStkRadar~IAgStkRadarClutterPatch% objects. It does this by calling the %Add:AgStkRadar~IAgStkRadarClutterPatchCollection~Add% method on the %IAgStkRadarClutterPatchCollection:AgStkRadar~IAgStkRadarClutterPatchCollection% interface returned by the %ClutterPatches:AgStkRadar~IAgStkRadarClutterGeometryComputeParams~ClutterPatches% property of the %IAgStkRadarClutterGeometryComputeParams:AgStkRadar~IAgStkRadarClutterGeometryComputeParams% interface passed as an input parameter to the %Compute:AgStkRadar~IAgStkRadarClutterGeometryPlugin~Compute% method. The Add method constructs a new IAgStkRadarClutterPatch object, adds it to the collection, and then returns it to the caller. The plugin should then set the new patches location and area.
