This item is from the PC 3D Graphics Accelerators FAQ, by Blair MacIntyre with numerous contributions by others. (v1.2).
The information on these boards were obtained from Diamond Multimedia Systems home page at http://www.diamondmm.com/
They contain the NVidia/SGS-THOMSON NV1/STG-2000 chipset.
The boards are PCI-based and sport a digital gameport for precise joystick control, as well as two video gameports that allow specialized, multi-player versions of Sega Saturn titles, such as the arcade hit Virtua Fighter Remix, to be played on Windows 95 PCs. It is expected to be initially shipped in late October at consumer prices starting from $249 - $299.
With Diamond Edge 3D accelerators, game developers can support resolutions as high as 1024x768 with 65,000 colors while still achieving fast, realistic action. In the past, this type of technology was available only to engineers and designers with prices topping $2,000.
The 3D functions of the Diamond Edge 3D were designed specifically for the consumer multimedia market where the primary application is interactive entertainment. Traditionally, 3D graphics were created by drawing large numbers of successive polygons using the CPU, which resulted in a tradeoff between detailed graphics and speed of interactivity. With the Diamond Edge 3D, the hardware engine accelerates polygon rendering of real-time, texture-mapped 3D images at the highest possible frame rates without unduly slowing the CPU. In addition, the Diamond Edge 3D can create realistic 3D graphics by using nine control points to create a curved surface, called quadratic texture mapping (QTM).
Features of the Diamond Edge 3D engine include fast polygon rendering, texture-mapping for photo-realism, quadratic texture-mapping for perspective correction and rendering of curved surfaces, as well as special effects including diffused lighting, specular highlights, reflection mapping and alpha blending for fog, smoke and transparency.
High Performance 2D Acceleration
The Diamond Edge 3D delivers fast 2D Windows acceleration at resolutions as high as 1280x1024, color depths to 1 billion and refresh rates of up to 120Hz.
The DRAM version of the Diamond Edge 3D, based on SGS Thomson's STG2000 multimedia accelerator chip, is available for PCI-bus in 1MB upgradable to 2MB (the Diamond Edge 3D 2120XL) or 2MB standard (the Diamond Edge 3D 2200XL.) The VRAM configuration, based on NVIDIA Corp.'s NV1 multimedia accelerator chip, is available for PCI in 2MB upgradable to 4MB (the Diamond Edge 3D 3240XL) or 4MB standard (the Diamond Edge 3D 3400XL.) Both chips are based on NVIDIA's NV1 technology. Diamond estimates pricing for the 2000 series to start at $249 to $299 and for the 3000 series to start at $399 to $449.
