>
Shaders are the key technology that allow game developers to program a
limitless range of more sophisticated effects in games that execute on the
graphics processor.
ATI Advantage:
>
SMARTSHADER™ technology supports and accelerates the latest game
effects, allowing gamers to see immersive, life-like worlds with an
unparalleled level of realism

SMARTSHADER™ 2.0 Examples
DirectX7.0 effects (no
shader support)
SMARTSHADER supports
DirectX9.0 which
enables effects such as
the night sky, light
glow, and shadows

SMARTSHADER™ 2.0 Examples
The same scene using
DX8.0 effects only
cannot properly render
the water effects as
intended by the game
SMARTSHADER support
for DX9.0 allows for
realistic water effects.
In this scene the images
of the rocks under the
water are effected by
the ripples of the water ,
the reflection of the wall
and the glare of the light

SMARTSHADER™ 2.0 Demos
>
This demo makes the best use of the
powerful and flexible vertex/fragment
shaders of ATI SMARTSHADER to
achieve dynamic simulation of fur
motion along with glossy fur shading
>
Matrix skinning allows for decent animation of
simple, bidirectional joints such as knees and
elbows
>
Bump mapping relies on light-reflection
calculations to create small bumps on the
surface of the object in order to give it texture

SMOOTHVISION™ Technology

ATI Product Support:
M22/M24 (MOBILITY RADEON X300/X600): SMOOTHVISION™ 2.1
> M26/M28 (MOBILITY RADEON X700/X800): SMOOTHVISION™ HD
>
>
Feature Description:
Provides better 3D image quality through features like Anti-Aliasing (AA)
and Anisotropic Filtering (AF) techniques.
> Anti-aliasing enhances image quality by smoothing jagged edges on object
outlines.
> Anisotropic filtering improves image quality by sharpening blurry textures
to bring out finer detail.
>
>
ATI Advantage:
>
ATI SMOOTHVISION™ is a set of technologies designed to enhance the
image quality of any game using advanced, high-performance filtering
technology even at high resolutions in the latest games without
performance degradation.

SMOOTHVISION™ Examples: Far Cry
Without Anti-Aliasing many
“jagged” lines are present in
a typical 3D scene
SMOOTHVISION supports advanced
multi-sampling for up to 6 samples
per pixel for “smoother” effect

M22/M24 (MOBILITY RADEON X300/X600): VIDEOSHADER™
>
M26/M28 (MOBILITY RADEON X700/X800): VIDEOSHADER™ HD
Feature Description:
>
>
A key feature of the video processing engine that allows it to tap into the
power of the programmable pixel shader units of ATI’s graphics solutions
ATI Advantage:
>
Allows shaders to be used to accelerate many different video processing
tasks, de-blocking (FULLSTREAM™), adaptive de-interlacing, frame rate
conversion, color space conversion, and much more. These features
greatly improve image quality without any negative performance effects.

VIDEOSHADER™ Demo: FULLSTREAM™
FULLSTREAM technology
dramatically changes the quality
of internet streaming video

VIDEOSHADER™ Demo: Adaptive De-Interlacing
“WEAVE” de-interlacing uses
lines from the previous or
next field to fill in the missing lines.
“BOB de-interlacing fills in the
missing lines by interpolating
from the lines that are present in
the current field. This
works well when there is motion
Adaptive per-pixel de-interlacing selects the
best blending algorithm (Bob and Weave) on a
per-pixel basis.

3Dc™ Technology

Feature Description:
>
>
M26/M28 (MOBILITY RADEON X700/X800)
new compression technology designed to bring out fine details in games
while minimizing memory usage.
ATI Advantage:
>
Exclusive ATI feature that allows for up to 4:1 compression, meaning game
designers can now include up to 4x the detail without changing the amount
of graphics memory required and without impacting performance to the
end-user, resulting in more realistic scenes and characters during
gameplay.

Why PCI Express enables
the visual age of computing
Eliminates AGP bottlenecks
> High bandwidth
bi-directional data transfer
> Scalable for future enhancement
and provides a unified IO
interconnect for the PC platform
> A foundation for
significant advancements
in graphics applications
> SW transparent

PCI Express Demo: “Pinnacle” Video Editing
>
Pinnacle Systems is a developer of advanced digital video editing software
>
>
The goal for the next generation of video editing applications is real time editing of
HD content.
>
>
software supports compositing of real-time 3D effects with multiple video streams from a
variety of sources
“Real time” is typically considered to be 30-60 fps
AGP does not have enough upstream bandwidth to support HD video transfers,
>
>
the CPU is forced to do all of the work and then pass the final output downstream across
the AGP bus for display.
the CPU must simultaneously decompress, edit,
blend, and compress multiple video streams.
>
Frame rate drops well below real-time levels on an
AGP-based system
>
PCI Express system can handle simultaneous HD video
streams and maintain interactive frame rates of over
30 frames per second.
