[Radiance-general] Hard-coding .cal and data files

[Sarith Subramaniam]

Hi Greg,

 

 

Thanks. I asked this question because I am interested in simplifying the
organization of files in a project. 

 

I have run into issues in the past with projects that have multiple
luminaire definitions. The image below is a screenshot from the directory
containing rad files for one such project. Add or removing luminaires, or
even sky definitions with .cal files, in a scene will be easier if I could
add or  replace rad files alone without worrying about the linking data
files. 

 

 



 

 

Thanks,

Sarith

Hi Sarith,

 

There is no way to incorporate the luminaire data directly in the Radiance
file other than some kind of reference.  What is your concern, exactly?  If
you don't want to have the full path name, you can store the data files in
the same file as source.cal and take off the leading directory, or add a new
directory to your $RAYPATH (or %RAYPATH%) environment variable and put the
data files there.

 

Having many sources refer to a common data file is one way Radiance saves
memory when you have many light sources sharing the same distribution.

 

Best,

-Greg

Hi,

 

 

Is it possible to hard-code a data or .cal file inside a rad definition ? 

 

I am generating a few luminaire definitions using a batch file and was
wondering if it is possible to avoid linking rad files to external files.
For example, in the luminaire definition below, is it possible to code the
.dat and .cal file inside the rad file ?

 

void brightdata 2RT8S_2_32_LP735_dist

5 flatcorr C:/rm/ies/2RT8S_2_32_LP735.dat source.cal src_phi4 src_theta 

0

1 1.54935

 

 

Thanks,

Sarith
