3D Software and Development Support
3Dfx Interactive 's Voodoo Rush is compatible with the Voodoo Graphics chipset and offers equivalent 3D features 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:
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 full 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.
