CineFX 3.0 Engine
The third-generation of the NVIDIA® CineFX™ engine unleashes the
power of the latest NVIDIA GPUs and streamlines the creation of
complex visual effects. Through the power of the Microsoft® DirectX®
9.0 Shader Model 3.0 and OpenGL® 1.5 APIs, programmers can now
develop shader programs utilizing these technologies and techniques:
Infinite length shader programs:
With CineFX 3.0 there are
no hardware-imposed limitations on shader programs. The
technology and speed advancements of CineFX 3.0 ensure
that longer programs will run blazingly fast.
Dynamic flow control:
Additional looping/branching options
and new subroutine call/return functions give programmers
even more choices for writing efficient shader programs.
Displacement mapping:
CineFX 3.0 allows vertex processing
with textures, providing a new level of depth and realism to
every component, surface, and character in a scene.
Displacement mapping allows developers to make subtle
changes in a model’s geometry with very little computational
cost.
Vertex frequency stream divider:
Effects can be efficiently
applied to multiple characters or objects in a scene, providing
individuality where models are otherwise identical.
Multiple Render Target (MRT) technology:
MRTs allow for
deferred shading, a technique where the lighting of a scene
can be done after rendering all of the geometry, eliminating
multiple passes through the scene. Photorealistic lighting can
be created while avoiding unnecessary processing time for
pixels that do not contribute to the visible portions of an image.
With the increased horsepower provided by the CineFX 3.0 engine,
developers can create more unique game features and effects than ever
before. New effects include subsurface scattering, providing depth and
realistic translucence to skin and other surfaces; soft shadows for
sophisticated lighting effects; accurately represented environmental and
ground shadows; and global illumination for incredibly photorealistic
lighting. All of these effects can be combined to create intricate,
detailed, true-to-life scenes that completely immerse you in the game
environment.
