Using BSDF materials

Hi everyone. I'm definitely a novice at using Radiance, but I am trying to
run simulations as close to reality as possible for simple scenes. I have
the lighting and geometry down, but would like to implement defining a
surface with a BSDF material. I have the BSDF file but have no idea where
to go from there.

Any assistance on how to pass this or include this in the command would be
more than appreciated!

Thank you,
Christian

Hi Christian,

Can you offer a few more details? Where did your BSDF file come from and what format is it in?

Dear Christian,

I made a little GUI that I essentially use for my teaching of RADIANCE to
PhD students. It is called Geronimo and was developed during my time at
EPFL. The idea of the tool was to see the effect of complex fenestration
systems represented by their BSDF in typical office rooms.

In short:
- you can download the latest version (1.3) on:
ftp://kaemco.synology.me/Geronimo
- you can find some information and a guide on: http://leso.epfl.ch/geronimo

You have a main GUI window to give options and start the simulation, and a
little command window in which you can see the started commands. It is an
easy was to learn by trying the shown commands and looking at the
corresponding .rad files.

Hoping this helps,
Best,
Jerome

Hi Christian,

If you want to learn more about BSDF materials in Radiance check Greg's
presentation here > (


)

There is an example for defining a Radiance material using an .xml file on
slide 7.

After you define the material you can use the name of the material similar
to other Radiance materials and assign it to the surface.
