Epic Games shows technology behind the DirectX 11 Unreal Engine Samaritan Demo at GDC 2011.
http://schedule.gdconf.com/session/12449Description: This talk will focus on next generation graphics effects developed for Epic's GDC 2011 Samaritan demo. Epic engineers, in collaboration with NVIDIA, extended the engine to support Direct3D 11 and add displacement mapping. This talk will explain the bumps encountered and overcome along the way, along with extensive details on how displacement mapping was exploited in the demo. The talk will also explain in detail the many other new graphical features highlighted in the demo: screen space surface scattering for skin rendering, deferred rendering with MSAA, short hair rendering, blurry reflections based on ray-casting an approximate scene, and high quality depth of field featuring custom bokeh.
