The NV1 from Nvidia , also known as SGS Thomson STG-2000 , was a 3D graphics chip for the PCI bus , which in 1995 came on the market and one of the first 3D accelerator was. The most common representative on the retail market equipped with this chip was the Diamond Edge 3D .

Technical

However, the chip did not use the usual polygon method of today's graphics chips to display 3D objects, but relied on so-called NURBS . Since a further development of the processor ( NV2 ) was to be integrated into a Sega console, which never happened, the Diamond Edge 3D equipped with the NV1 had two connections for one in addition to a sound subsystem ( Sound Blaster compatible) Sega game controller . The list of supported games was ultimately quite short (all came from Sega, e.g. Virtua Fighter ), and the rather "exotic" NURBS technology did not catch on.
