Hi all! Thanks to Schorsch, I fixed some problems related to the Cygwin Radiance binaries that I compiled some days ago. Now they also work and output stdout and stderr in the normal Cygwin console. Here's the link once again: http://www.dream.unipa.it/dream/pub/dot/anselmo/radiance/03.php#binaries And many thanks to Schorsch! -- francesco
