hat are farther away are blurrier. However, this does not look real since the fog obscures and fades the colors of the distant. With the T-buffer, depth of field is a reality, making rendered images much more realistic. The T-Buffer has two other abilities: soft shadows and soft reflections. Shadows and reflections in frames that pass through the T-Buffer look more realistic.Voodoo5 5500 uses T-Buffer Digital Cinematic Effects engine smoothes motion and improve image quality or to exaggerate motion for special effects.” This technology powers the card’s most important attribute, Real-Time Full-Scene Hardware Anti-Aliasing (FSAA). Full-Scene Anti-Aliasing (FSAA) is the removal of aliasing artifacts. Aliasing artifacts come in two forms: "jaggies," or stairstepping of diagonal lines, and flashing or "popping" of very thin polygons. These spatial artifacts occur because the scene being rendered is under sampled. Full-scene anti-aliasing smoothes the jagged lines and eliminates the scintillating of very thin objects by taking many samples of the scene and blending them together. The result is a much smoother, far more realistic and pleasing image. In order for this technology to deliver the best image quality, each image must have 16-30 copies scent through the T-Buffer. Unfortunately with the processor on the card this is not possible. It requires too many times more fill-rate and geometry and triangle processing power than is now available. 3dfx’s current T-buffer uses many fewer passes (somewhere around 4) to keep within an acceptable frame rate. Without the full 16-30 passes, however, discrete images of reflections/motion blurs may be observed, rather than smooth transitions. Fill RateThe Voodoo5 5500 has a fill rate of 667MegaTexels. Fill rate is the number of texels that can be rendered per second. A texel is the smallest graphical element in a two-dimensional (2-D) texture mapping used to "wallpaper" the r...
