Examples with more kinds of BRDFs, BSSRDFs

[benjamin-heasly]

We would like to have an example that shows rendering with more types of BRDFs and BSSRDFs than we currently demonstrate. We believe that any material type supported by the renderers can be rendered within the RenderToolbox environment, but we have not tried it. Since the supported materials are renderer specific, this example would also illustrate the syntax we use for renderer specific features.

It would be nice if this example showed how to use empirically measured material properties. Since these may come in RGB format, such use would interface with the spectral promotion features of the renderers.

I'm searching for a recipe which would allow me to use BRDFs from https://www.merl.com/brdf/ or http://btf.utia.cas.cz/?brdf_dat_dwn – is this currently feasible?
