I just have been able to see the last minutes of the presentation on relevant optical measurements by Jacob. Anyways, even from the schedule, it is really nice to see a coherent terminology finally - no more BTDF/BRDF/BRTDF (or all of these without F), just BSDF everywhere. Somehow I do not like the F (as the abbrevation is usually not used to describe a function but discrete data, as Jacob just demonstrated when talking about measurements), but it is still less confusing like that. Maybe the Radiance community will be the first having such a stringent terminology :slight_smile: I am excited to see the coming presentations...

Cheers, Lars.
