winxmit.cal

Hi,
I'm trying to use gensky as shown on chapter 3.1.3 of the Radiance book.
I have problems because the program can't find winxmit.cal.
Can anyone advice me on where I should keep winxmit.cal?

Thanks,
Alex

you should find it on the web site of radiance...
may be the RAYPATH is not set up... or the libraries are missing...

anyway:

winmix.cal is:

--------------------start of file-------------------
{
  winxmit.cal - window transmittance function.

  4/24/86
}

winxmit = 1.018 * Rdot * (1 + (1 - Rdot*Rdot)^1.5);

--------------------end of file------------------------------

after saving the file with the right name you can simply place it in your
scene directory or add the RAYPATH varable to your configuration file that
is used to define the location of radiance libaries
usually such file is

1 - .bash_profile

after a good back up of the file add:

RAYPATH=.:/your/system/path/to/radiance/libraries
export RAYPATH

or

2 - .cshrc

after a good back up of the file add:

setenv RAYPATH .:/your/system/path/to/radiance/libraries:{RAYPATH}

hope it helps,
giulio

PS
different directories can be defined, just separate them with " : "
  " . " stays for current directory.
