The S3Ó ViRGEÔ integrated 3D video/graphics accelerator (hereinafter referred to as ViRGE) enables development of compelling interactive entertainment, education, and presentation applications for the mainstream personal computing world.
64-bit S3d Engine
The S3dÔ Engine provides 2D acceleration for excellent Windows applications performance and a full-featured high-performance 3D rendering engine for games and other interactive 3D applications.
The S3d Engine incorporates the key Windows accelerator functions of BitBLT, line draw and polygon fill. 3D features include flat shading, Gouraud shading and texture mapping support. Advanced texture mapping features include perspective correction, bi-linear and tri-linear filtering, MIP-Mapping, and Z-buffering. The S3d Engine also includes direct support for utilizing video as a texture map. These features provide the most realistic user experience for interactive 3D applications.
Other advanced features of the S3d Engine include S3 proprietary compressed texture formats for improved performance and reduced memory requirements, as well as support for S3’s MUX buffering (pat. pend.) feature, which allows for Z-buffering support with no additional memory requirement.
Streams Processor
The S3 Streams ProcessorÔ provides the stretching and YUV color space conversion features required for full screen video playback with both software CODECs and hardware MPEG-1 sources.
The Streams Processor allows simultaneous display of graphics and video of different color depths. For example, it is possible to display 24 bpp-equivalent video on top of an 8-bit graphics background. This saves memory bandwidth and storage capacity while permitting higher frame rates.
S3 Scenic Highway
The S3 Scenic HighwayÔ allows lowest cost direct connection to S3’s Scenic/MX2 MPEG-1 audio and video decoder as well as video digitizers such as the PhilipsÓ SAA7110/SAA7111.
