Agreed. You'd be much better of using Linux or OS X if any of it is  
available to you.
Have you tried the LEARNiX bootable CD before?

Possible.

Simple test: run the command with the full path instead of only the  
command name

$ /cygdrive/ray/bin/rvu -vp 2.25 .375 1 -vd ....

If that works it is a PATH issue and you have to add the directory  
where all your compiled
Radiance programs reside to your $PATH environment variable. In short  
this is a list of
directories in which the bash will search for a command.

You can read something about configuring your environment here:

Please note that I have no experience with Cygwin myself and that I  
can only give you
generic Unix advice. This should still work in general terms because  
Cygwin is just
creating a Unix like environment under Windows.


Hth,
Thomas
