[Radiance-general] rtcontrib scripts

[Jack de Valpine]

Hi Dave,

What kinds of problems are you having with Perl? You should be able to 
do most anything you want with Perl. The main problem area can be if you 
are feeding data to into and/or out of radiance programs and end up with 
buffering problems. For example I only recently learned that there is a 
'-u' switch for rcalc which causes output to be flushed after each 
record. This came in real handy for a perl program that uses open2 to 
both write to and read from an rcalc process.

PS, as others on this list know I am a pretty strong advocate of Perl. 
However, there is also a strong group who use Python for Radiance 
related scripting. Of course Greg is all about shell.... Nevertheless, 
as you indicate fairly good knowledge of Perl this might still be the 
best place to try to get things working....
