This demo based on the Siggraph 2004 work by Paul Debevec (http://www.debevec.org) consists of over 15 million polygons, derived from a real-world laser capture of the actual Parthenon in Athens, Greece.
Image based lighting techniques and a novel LOD algorithm are used to render this dataset in real-time on the Radeon® X1800 graphics processor.
The ATI Parthenon demo is in one word .. breathtaking.
