Re: [Brad] Help:Setting up a radiance system--brad

[Rob Guglielmetti]

This may or may not help you, but I've attached a shell script I wrote 
called ltview.  This takes a luminaire.rad file that was created with 
the ies2rad utility and loads  in a box with one side removed, increases 
the -ds parameter (so the light pattern is better defined) and sets up a 
view looking into the box along the y axis, in rvu.  It's just a handy 
little way to spot check that your ies2rad went smoothly.  I have used 
this to uncover errors in the ies files before.

The -bs switch controls the size of the box; the default is 24, because 
I used to work in inches in my previous life.  That would give me a 4' 
square box.  So to use this with a luminaire file that you converted in 
meters, set -bs to .61 or so, for a  box that would just contain a 4' 
fixture.   You  can of course make the box any size you want, but I 
usually make it tight to the fixture so that I can see the beam accurately.

I'm not using Brad at the moment so I can't give specific advice with 
those issues, but I thought I'd offer my utility as a useful spot checker.
