Features and Specifications
Video-338/348PCI series
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 identica l.
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 creat e in t r icate ,
detailed, true-to-life scenes that completely immerse you in the game
environment.

NVIDIA CineFX 3.0 is poised to unleash a new level of programming
creativity. With full DirectX 9.0 Shader Model 3.0 suppor t, the newest
Video-338/348PCI series will soon power a new generation of games
with unmatched realism, digital worlds with mind-blowing complexity,
and lifelike characters that move through cinematic-qualit y
environments.
Intellisampl e T echnology
The industry’s fastest antialiasing delivers ultra-realistic visuals, with no
jagged edges, at lightning-fast speeds. Visual qu ality is taken to new
heights through a new rotated grid sampling pattern.
UltraShadow II Technology
Video-338/348PCI series of GPUs delivers the patent-pending NVIDIA®
UltraShadow™ II technology, which can be applied to today’s games to
build stunning visual effects and to create distinctive digital
environments. With a system powered by a Video-338/348PCI series
GPU, anytime a game or application calculates shadows, UltraShadow
II will enhance the overall performance. With UltraShadow II hardware,
the more passes that are required for the lighting and shadow
calculations in a scene, the more significant the performance
improvement, with the most complex scenes achieving the most
noticeable results.
Thus, emerging next-generation games, that employ multiple light
sources with many visible objects in each scene—such as Doom III from
id Software—will see dramatic improvements in execution speeds. The
technology advancements in UltraShadow II also deliver a 4×
performance increase (compared to the previous generation) for passes
involving shadow volumes.
NVIDIA UltraShadow II gives developers the ability to calculate shadows
much more quickly by eliminating unnecessary areas from
consideration. By defining a bounded portion of a scene (called “depth
bounds”), and focusing calculations only on the area most affected by
the light source, developers can greatly accelerate the shadow
generation process. With the ability to fine-tune shadows within critical
regions, developers create incredible visualizations that mimic reality,
and still achieve awesome performance for fast-action games.
UltraShadow II also works perfectly with NVIDIA® Intellisample 3.0
technology to ensure that shadow edges are properly antialiased.
