The 3Dfx Interactive Voodoo Rush accelerator provides the highest performance 3D solution with full PC compatibility for multimedia graphics acceleration. The 3Dfx Voodoo Rush is a high performance 3D accelerator that works in conjunction with a compatible 2D accelerator. The 3Dfx Voodoo Rush seamlessly connects to the 2D graphics accelerator to function as a high performance 3D engine for PC games or professional applications in the CAD or authoring markets. This unique architecture allows full, simultaneous access to the multimedia features of the 2D device and the advanced 3D functions in the Voodoo Rush 3D accelerator.

• Alpha blending
• Per-pixel special effects: fog, transparency, translucency
• Texture compositing, morphing, animation
• Linear frame buffer access

Leading Performance

• Up to 45 Mpixels/sec performance, with advanced features like bi-linear filtering LOD MIP-mapping, Z-buffering, alpha-blending and fogging enabled
• Over 1M triangles/sec for filtered, LOD MIP-mapped, Z-buffered, alpha-blended, fogged, textured triangles

3D Rendering Resolution Table

3Dfx Interactive 's Voodoo Rush architecture renders 3D images either in full screen mode or in a window on the desktop. Performance is optimized for both full screen rendering and 3D in a window. The table below shows the maximum resolutions in each mode. Voodoo Rush renders to virtually any resolution, limited only by the available display memory.

3D Software and Development Support

3Dfx Interactive's Voodoo Rush offers equivalent 3D features to the Voodoo Graphics chipset while providing full PC multimedia support. Driver support includes the 3Dfx Interactive Glide™ programming library for low level access to the 3Dfx 3D engine. In addition, Voodoo Rush provides the most complete support and highest performance for Microsoft 's Direct3D API. APIs supported include:

• 3Dfx Glide

• Microsoft Direct 3D

• QuickDraw 3D Rave

3D Performance

For high performance 3D games, 3Dfx Interactive Voodoo Rush delivers over 45 Mpixel/second texture mapped performance and over 1M full-featured triangles per second. Unlike other entry level 3D accelerators, Voodoo Rush offers high performance with all features turned on. This 3D power translates into fast action games with full, interactive frame rates. For professional applications, Voodoo Rush delivers crisp screen updates and fast previews of high complexity 3D objects and animation sequences.
