quads were used industry wide in the early 90s. at that time it was not yet decided if quads or triangles are better. you can do lots of crazy things with quads like warping them at the mid points to create b-splines, resulting in perfectly curved surfaces. you can't do that shit with polygons and you couldn't approximate it until pixel/vertex shading became the norm. animation studios like Pixar used those.
otherwise Nvidia would not have banked on quads either, since the NV1 can do b-splines/nurbs in hardware, but nobody ever used this because it would've been a vendor lock-in. it's why nvidia wanted so hard to have their chips go into the saturn successor, but they couldn't demo the NV2 to japan so sega quietly backed away, leaving them with a large donation for their troubles. that money was enough to finish the chip, have the quads and b-splines fused off, and calling it NV3 aka RIVA128. it still had the bullshit pipelined hardware architecture of the NV1/2, you just couldn't see it because it was all hidden behind the drivers.
