The NV1 was Nvidia's first graphics accelerator, introduced in May 1995 and released later that year as a multimedia PCI card. Manufactured by SGS-Thomson Microelectronics, sometimes under the model name STG2000, the chip was sold in retail by Diamond as the Diamond Edge 3D card. The NV1 stood out for its use of quadratic texture mapping, a departure from the triangular primitives favored by competitors. The use of quadratics made it possible to port games from the Sega Saturn; however, after the NV1 was introduced, Microsoft announced that DirectX would exclusively support triangle primitives. As a result, the NV1 failed to gain traction in the market.
