Interesting choice with the Mies Van Der Rohe Pavilion, because as stunning as it is in real life, it's simple geometry actually makes for a bit of a boring tech demo. Still looks very impressive though.
I this is a bit of legacy ( like the Stanford Bunny ). One of the seminal work of lighting was Photon mapping by Henrik Jensen , and he used Ludwig Mies van der Rohe's structure as an example ( http://graphics.ucsd.edu/~henrik/animations/jensen-the_light... ). Keep in mind this was done 14 years ago! It was a genuine wow moment for me back then!
