The BRDF explorer is a re-imagination of WDAS's original BRDF explorer tool using ANARI. It was developed as a project for the ANARI Hackathon in October 2024. The tool can as of now load user-defined BRDFs as C++ plug-ins (see the plugins folder for an example of how to do this).

Through BRDF parameter introspection (user
implements the functions querySupportedSubtypes() (the BRDF names) and
querySupportedParams() (list of accepted parameters)) an (Im-)GUI to manipulate BRDFs
is dynamically created. The BRDF explorer currently supports visualizing the BRDF surface
through the eval() function; support for sampling is already there but is currently
commented inside the code. This would be easy to hook up but I didn't find the time
during the hackathon.
