[Radiance-general] Reading light vectors tom txt and automate rendering

[Brajesh Lal]

Hi,

I have txt file with light vectors ( x, y and z vectors separated by tabs) . 
Same scene has to be rendered (using rpict) with each set of light vector and 
saved as different .hdr file.
Instead of doing one by one, i need to automate the process by creating a some 
script (may be using rif file and rad command), which can update the light 
vectors in the scene file (.rad file).
I am confused 

1. How do i declare the variable for light vectors and update the light vectors 
in the scene file ?
2. What are the steps to do it ? 

( I am still using 3.9 version)
Best Regards, 
Brajesh Lal
