The S3 ViRGE/VX integrated 3D video/graphics improved performance and reduced memory accelerator (hereinafter referred to as ViRGE/VX) requirements, as well as support for S3’s MUX enables development of compelling interactive buffering (pat. pend.), which allows for Z-buffering entertainment, education, and presentation applications support with no additional memory requirement. for the mainstream personal computing world. It also provides the highest performance for high-end desktop Streams Processor applications. The S3 Streams Processor provides the stretching 64-bit S3d Engine and YUV color space conversion features required for full screen video playback with both software CODECs The ViRGE/VX S3d Engine provides 2D acceleration and hardware MPEG-1 sources. The Streams for excellent Windows performance and a full-featured Processor allows simultaneous display of graphics and high-performance 3D rendering engine for games and video of different color depths. other 3D applications. S3 Scenic Highway The S3d Engine incorporates the key Windows accelerator functions of BitBLT, line draw and polygon The S3 Scenic Highway allows lowest cost direct fill. 3D features include flat and Gouraud shading and connection to S3’s Scenic/MX2 MPEG-1 audio and texture mapping. Advanced texture mapping features video decoder as well as video digitizers such as the  include perspective correction, bi-linear and tri-linear Philips SAA7110/SAA7111. filtering, MIP-Mapping, and Z-buffering. The S3d Engine also includes direct support for utilizing a 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
