Highlights of the demo include:
-------------------------------
• Tessellation enables a continuous ramp on the level of detail, more than
doubling the total triangle count and providing up to a 500x increase in detail
on the nearest objects.
• Three dimensional displacement maps allow greater detail than simple height maps.
• The demo positions and renders over 600 million triangles per second with a
single GPU.
• The city is procedurally generated. The buildings are constructed from a small
set of objects into a city of complex structures using a set of rules called an
L-system.
• In the area surrounding the viewer, over a million meshes are arranged by the
L-system, including roughly 500,000 light sources.
• As the viewer moves, the demo endlessly (hence the name) generates more of the
city to keep the viewer surrounded by buildings.
• The L-system randomly selects elements to assemble so each block looks different
from the last but if you return to a place you saw before, it'll regenerate the
same buildings you saw previously.
• Split screen rendering modes operate in eye space so they look correct in 3D Vision.
• Screen-space ambient occlusion enables high quality shading on randomly
generated and dynamic geometry which cannot be accomplished with precomputed texture
maps.
