Yes, as I recall, we spent the better part of a day
downloading what were "suppose" to be VRML clients.
In the end, we concluded that VRML is a standard whose
time has passed. :-)

Thanks David. Yes pictures are exactly what I want. I work with somebody
who knows IDL and who can make me some IDL programs. I want to be able to
pass this IDL code to a Java class which can execute the IDL and return a JPG
(or a reference to where a JPG is located on the file system).
If there are any example codes out there which I might be able to look at in
order to get an idea as to how this is done then please point the way. I
have tried to look at what RSI offers as example ION-Java code but it appears
that the link is dead (http://ion.researchsystems.com/IONJava/)
Thanks again for your help...

Things like this seem to defeat the purpose of putting IDL application's
output on the Web. If I need to download 10 Mb of software to use a web
site, I am not using that site. I know its funny, but I still use a
modem to access the net from home. I will sign up for DSL (Dedicated
Satellite Link) once I get that check form David :-)
For this same reason, I think it is not a good practice to start up your
front web page with a Java applet that takes half an hour to load over a
28k modem, just to display a rolling banner with your company's logo on it.
