Just a couple points to add about displaying satellite images. The Simple application described in Section 2.1 of the VisAD Developers Guide displays a time sequence of satellite images. Also, some of the cases of examples/DisplayTest display images from various file formats. Second, VisAD is currently pretty slow. This is because it uses Java3D which is currently in alpha release and cannot yet work with efficient Java compilers (e.g., JITs, HotSpot). Thus the 3-D rendering speed isn't bad, but all the other code runs by pure interpreter and is slow. This includes the code in VisAD that converts an image into a Java3D scene graph. Speed will greatly improve once Java3D can work with good compilers. Also, we are working on a Java2D dispay option which will be useful for displaying images without 3-D graphics hardware.
