Question Add custom BRDF models as LUTs 

Forum: Processes Involving Optical Photons

From: Jan Christoph Terasa <Jan Christoph Terasa>


is there a way to add a custom LUT representing a (measured) BRDF to use for optical tracking in GEANT4? I noticed that there are LUT for some materials in the RealSurface data files, but I'd really want to use custom ones for my own materials.

If not, what is the simplest and safest way to implement that, I have no problems changing the GEANT4 source code directly to fulfill my goals (e.g. add the possibility to add a path to a custom BRDF LUT file when defining an optical surface)?

regards, Christoph
