[Radiance-general] scripting problem

[Thomas Bleicher]

Valeria

The syntax for gensky is

     gensky month day hour:minute [anything else]

In your script you create

     gensky -a 45.5 -o 12.33 -m -15 month:day:hour -u -g 0.2

which is not accepted by gensky. Use the line

     gensky $mo $da $hh":00" -a 45.50 -o -12.33 -m -15 -u -g 0.2 >  
sky.rad

instead of your command. I assume that the CSH syntax
otherwise is correct. I have not checked that the output
of $hh":00" returns something like "13:00".

I also noticed that you use a uniform sky here (-u).
This is not realistic sky distribution and only appropriate
in specialist cases. If you want a "standard" sky you should
use "-c" to create an CIE overcast sky (probably not very
accurate for Venice either - I'm sure you get some sun there.).

Regards,
Thomas
