	Make a 3D rendering of a panoramic scene with some 3D vector objects added (e.g., a building, a tower etc).		Make a 3D rendering of a panoramic scene with some 3D vector objects added (e.g., a building, a tower etc).
			We use GRASS here to get all data into a unique coordinate system (esp. for the 3D vector objects which are usually not geocoded).
