Detailed Description

ossimGeoPolyCutter.

This classes overrides the 2-d counter part ossimPolyCutter. It will automatically map 2-D to 3-D (ground) polygons if you add 2-D polygons and will automatically compute the forward transform when adding a ground polygon.

you can set the view trough the ossimViewInterface by calling setView(object, true); it will cast to an ossimProjection and use that as the transformation. For igen this is set automatically and does not need to be set by the user.

This class has no keywords but does use 2 prefix values to store out the view and the ground polygon for example if we have only one polygon then here is a sample keyword list for the polygons: NOTE we can have any number of polygons just increment the geo_polygon0 to geo_polygon1 .. geo_polygonN for the Nth one
