<meta name='descriptioncontent='Test browser ability to map a greyscale with alpha-opacity PNG file and a greyscale with binary transparency PNG file onto the faces of complex geometry. 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.'/>
