Announces Breakthrough 3D Technology that Brings Realtime Cinematic Effects to Consumer
PCs
3dfx Previews Real-Time 3D Graphics for Consumer PCs Featuring Full-Scene Spatial
Anti-Aliasing, Motion Blur, and Depth of Field Acceleration
SAN JOSE, Calif., – August 2, 1999 – 3dfx Interactive® Inc. (NASDAQ: TDFX)
today demonstrated a breakthrough real-time digital effects technology for the consumer PC
with its T-Buffer™ cinematic effects technology, once again raising the bar for
high-performance, realistic 3D graphics. The T-Buffer technology dramatically improves the
rendering capabilities for consumer PCs, bridging the “realism” gap that exists
today between motion picture and photographic imagery and computer-generated images. With
the T-Buffer announcement, 3dfx comes one step closer to fulfilling its mission to bring
advanced cinematic effects and realistic imagery to consumers.
“3dfx’s dedication to developing high-quality rendering, lifelike realism, and
stable solutions has paid off,” said Scott Sellers, executive vice president and
chief technical officer . “Our T-Buffer technology represents the next step in
advancing the quality and performance of 3D graphics on the mainstream PC desktop.”
3dfx will feature T-Buffer technology in its next generation products, marking the first
time sophisticated, high-end cinematic effects will be available in real-time for consumer
PCs. Up until now, creating the effects accelerated by the T-Buffer technology was
reserved for the special effects elite: primarily professionals who could afford the
excessive costs associated with developing Hollywood-like digital effects on professional
workstations.
“The difference in rendering quality when using the T-Buffer effects is dramatic. No
longer will users be satisfied with the sharp, jagged polygon edges and unrealistic motion
effects common in today’s 3D accelerators. Instead, consumers will now experience
almost photorealistic real-time rendered images. By making this technology available at
consumer price points, a new generation of real-time, interactive 3D applications will
soon be realized,” said Gary Tarolli, chief technical officer at 3dfx.
“3dfx's T-Buffer technology and incredible texture fill rates, combined with the
Intel Pentium® III processor's SSE accelerated geometry and lighting technology, will
bring forth an exciting cinematic experience to PCs this fall,” said Pat Gelsinger,
Intel's vice president and general manager of the Desktop Products Group. “We are
pleased that 3dfx is taking advantage of the Pentium III processor's robust performance to
complement its T-Buffer technology and deliver exciting new effects as a result.”
Designed to dramatically raise the level of quality of 3D graphics rendering, the T-Buffer
technology enables cinematic effects never before available on consumer PCs at real-time
frame rates essential to attaining and experiencing true-to-life imagery. Chief among
these are real-time Full-Scene Spatial Anti-Aliasing, which removes the appearance of
jagged edges in a rendered scene, and real-time Motion Blur, which dramatically improves
the rendered realism for fast-moving objects . The T-Buffer technology also allows for the
first time acceleration of Depth of Field effects commonly used in professional
photography and cinematography.
Spatial Anti-Aliasing, Motion Blur, Depth of Field, and related techniques are key to
producing real-life imagery, and can mean the difference between viewer belief and
disbelief of an image’s realism. To the viewer’s eye, the sharp, jagged edges,
the absence of blurred images during movement, and the lack of depth reference commonly
found in images rendered by today’s 3D accelerators are actually indicators of
unrealism since these artifacts do not occur naturally in real-life, photography, or film.
As a result, the human eye registers these poorly rendered scenes as artificial, and the
attempt to convey realism is lost. For the first time on consumer PCs and high-end visual
simulation systems all of these realistic effects can be accelerated in real-time by the
breakthrough T-Buffer technology, thus allowing for more compelling and immersive 3D
applications.
