A detailed Summary of semiconductor diode

I PURPOSE OF REPORT This report will compare Voodoo5 5500 with NVIDIA's Geforce2 Ultra to determine which accelerator provides the best performance. Both companies' accelerators share the same goal, to bring the highest visual quality possible. Although both companies share the same goal, their approaches are extremely different. Cost will also be addressed. The following features will be examined: - Dual 3dfx VSA-100 - T-Buffering - Fill Rate - 32-bit Z-Buffer/Stencil - Synchronous dynamic random access memory - 32-bit Color II 3D IMAGING 3D objects are created by connecting two-dimensional polygons. Objects appear to be 3D dimensional because the computer calculates the necessary angles to give the illusion of depth. The computer then assigns a give texture to each object, textures are the covering of the object. Like in the real world, different textures have different properties, like color, luster, opaque, etc. These objects are then displayed on the computer's monitor. M!

any 3D objects can be combined to create a 3D environment. A 3D environment is the computers generation of a make believe world. When the camera, the point of view within the 3D world, moves, the computer calculates the height, width, depth and the lightin

r The Voodoo5 5500's dual 3dfx VSA-100 chips support full 32-bit color accuracy, meaning that is can display approximately 32 thousand different colors on your monitor. The dual VSA-100 chips are able to deliver a maximum 2D rendering ability 2048 pixels by 2048 pixels, displaying amazing detail of 2D images. IV GeForce2 Ultra The GeForce2 Ultra Graphics Processing Unit (GPU) is NVIDIA's latest 3D accelerator. The card features a 250MHz GeForce processor, 64MB of Double Data Rate (DDR) SDRAM running at 230MHz (giving an "effective" clock speed of 460MHz). 250MHz GeForce 250MHz GeForce processor can render 31 million triangles per second . Fill Rate The GeForce2 Ultra has a fill rate of 2 GigaTexel's per second . FSAA GeForce2 Ultra uses FSAA technology. The GeForce2 Ultra's use of FSAA does not include a T-Buffer and does not offer depth-of-field blur, soft-shadows or soft reflections. The GeForce2 Ultra does include a feature like to Z-Buffer to increase realism, the feature !

nce 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 sc!

make millions of complex mathematical calculations every second. This can make games and 3D graphics applications slow and jerky as the computer gets caught up rendering 3D images in addition to running the program. 3D accelerators solve this problem. When you install a 3D accelerator, the 3D graphics previously rendered by the CPU (your computer's processor) are now rendered by the 3D accelerator. This significantly increases the performance, visual effects, and drastically improves the 3D experience. III VOODOO5 5500 The Voodoo5 5500 is 3Dfx's latest 3D accelerator. The card features dual 3dfx VSA-100 chips, Real-Time Full-Scene HW Anti-Aliasing, the exclusive T-Buffer Digital Cinematic Effects engine, Z-Buffer/Stencil, 32-bit Z-Buffer/Stencil, 64MB of graphics memory, 32-bit color. Dual 3dfx VSA-100 3D objects are broken down into primitive polygons using triangles. The 3D processor(s) then use primitive polygons to perform calculations (Z-Buffering, FFSAA, etc.) The Voodoo!
