public class complex_rgb_alpha extends Object

Test browser ability to map an RGB with alpha-opacity PNG file onto the faces of complex geometry. An red, green and blue version of the VTS logo, with transparent background should onto an Extrusion (palette plus binary transparency), an Elevationgrid (RGB plus alpha) and an IndexedFaceSet (RGB plus binary transparency). Because alpha opacity is set to 0 (transparent) for the image background on the Extrusion (left) and IndexedFaceSet (right), and binary transparency is set for the PNG image mapped to the middle geometry (the ElevationGrid), all geometry will be transparent, except for the VTS logo. The transparent image will be mapped to each geometry using default texture mapping rules.
