A greyscale version of the VTS logo, with transparent background should onto an Extrusion, an Elevationgrid and an IndexedFaceSet. Because alpha opacity is set to 0 (transparent) for the image background on the Extrusion (left) and IndexedFaceSet (right). The middle geometry, an ElevationGrid, has a binary transparent background color. All geometry will be transparent, except for the VTS logo. The transparent image will be mapped to each geometry using default texture mapping rules.'/>
