In 1988, Silicon Graphics developed powerful workstation computers based on the MIPS CPU and the IRIS graphics system, which later became OpenGL. The company then ventured into the PC space with the IrisVision card. Gary Tarolli, Scott Sellers, and Ross Smith, former SGI employees, founded 3dfx Interactive in 1994, focusing on consumer 3D acceleration. Innovations included chips for perspective-correct texture mapping and Gouraud shading. Despite successes with the Voodoo Graphics and Quake compatibility, 3dfx faced challenges with the Voodoo Rush and competition from ATI and NVIDIA. The company ultimately declared bankruptcy in 2000, leading to its acquisition by NVIDIA.
