My first video accelerator was the Nvidia NV-1 because a friend of mine was on the design team and he assured me that NURBs were going to be the dominant rendering model since you could do a sphere with just 6 of them, whereas triangles needed like 50 and it still looked like crap. But Nvidia was so tight fisted with development details and all their "secret sauce" none of my programs ever worked on it.

Then I bought a 3DFx Voodoo card and started using Glide and it was night and day. I had something up the first day and every day thereafter it seemed to get more and more capable. That was a lot of fun.

In my opinion, Direct X was what killed it most. OpenGL was well supported on the Voodoo cards and Microsoft was determined to kill anyone using OpenGL (which they didn't control) to program games if they could. After about 5 years (Direct X 7 or 8) it had reached feature parity but long before that the "co marketing" dollars Microsoft used to enforce their monopoly had done most of the work.

Sigh.

Wow, this sounds like those little cases where a few different decisions could have easily led us down into an alternate parallel world :)

Can someone expand on why NURBs didn't/don't win out against polygons?

Could this be like AI/ML/VR/Functional Programming, where the idea had been around for decades but could only be practically implemented now after we had sufficient hardware and advances in other fields?

My guess is: 'brute force and fast' always wins against 'elegant but slow'. And both the 3dfx products and triangle rasterization in general were 'brute force and fast'. Early 3D accelerator cards of different vendors were full of such weird ideas to differentiate themselves from the competitors, thankfully all went the way of the Dodo (because for game devs it was a PITA to support such non-standard features).

Another reason might have been: early 3D games usually implemented a software rasterization fallback. Much easier and faster to do for triangles than nurbs.
