Re: Mapping

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.
 
Cheers,
Bill
