Member Function Documentation

addGeometry()

OGRErr OGRTriangulatedSurface::addGeometry ( const OGRGeometry *  poNewGeom )

virtual

Add a new geometry to a collection.

Only a POLYGON can be added to a POLYHEDRALSURFACE.

Returns

OGRErr OGRERR_NONE if the polygon is successfully added

Reimplemented from OGRPolyhedralSurface.
