The increased horsepower and new technology of the CineFX 3.0 engine empower
programmers to create features and effects that are more unique than ever,
including these:

Subsurface scattering. Skin and surfaces take on depth, with variations that
show realistic translucent qualities (Figure 8).

Soft shadows. Shadows take on a less harsh look with this technique. The
shadow’s edges that are created from the lighting and objects in the scene are
softened, more accurately depicting the visual look that would occur

Environmental and ground shadows. Shadows can be cast onto
environmental surfaces, such as grasses and other vegetation, without
introducing eye-catching anomalies or slowing performance. The 32-bit pipeline
allows ground shadows to accurately move as the viewer’s point of view
changes.
Global illumination. One of the biggest differences between prerendered and
real-time graphics is lighting. To produce the most realistic imagery possible,
film renderers spend hours determining how light bounces between objects in a
scene. With support for near-infinite-length pixel shaders, and floating point
filtering and blending, these incredibly complicated effects can be approximated
in real time, bringing higher levels of photorealism to real-time applications.
