rgb_alpha_png.x3d

Test browser ability to map an RGB PNG file (with background alpha-transparency set to 0 for the two left geometry, and binary transparency onto the faces of primative onto a sphere (RGB plus alpha), cone (RGB plus alpha), cylinder (RGB plus transparency) and box (palette plus transparency). Because the image background is transparent, all geometry, except for the cover the entire surface, and wrap counterclockwise from the back of the sphere. For the cone, the texture should wrap counterclockwise (from above) starting at the back of the cone. A circle cutout of the texture is applied right side up to the base of the cone when the cone is tilted toward the -z axis. For the cylinder, the texture should wrap counterclockwise (from above) starting at the back of the cylinder. A circle cutout of the texture is applied right side up to the top and bottom caps of the cylinder. For the box, the texture should be applied right side up in its entirety to each face of the box.
