batch renders with explicit direct and diffuse irradiance

Dear All,

I am fairly new to the use of Radiance, at the moment I am trying to run
a series of batch renderings in Radiance (for windows, using ecotect as
interface).
So far everything is fine, but if I want to use the -B and the -R option
in order to explicitly define the horizontal diffuse and direct
irradiance values from a weather file for each different sun position, I
do not know where or how I should enter the list of values.

Any suggestion on how to do it (if it is possible) would be very
appreciated,

Cheers,

Giovanni

Hi Giovanni.

I'm not quite clear if you want to use the Radiance tools from the command line
or if you expect that there is a 'use these values' button in EcoTect.

In the fist case you have to find the file that contains the sky description in
the scene that's exported by EcoTect. -B and -R are options to the gensky
command that should be on one the lines in this file.

For a batch calculation of different values you have to loop over

1) modify the gensky command
2) recreate the scene octree
3) do the calculation again
4) move the images (or rtrace results) to a different place

This is possible with a bit of command line scripting.

Regards,
Thomas
