Pyramid3D Full PDF here Project X TriTech's Pyramid3D graphics chip became Glaze3D by BitBoys. No matter what new form it took when it resurfaced, it was always vaporware for many years. However offspring of the tech presently exists in Qualcomm's Adreno GPUs within their Snapdragon processors. And VM Lab's Project X became the Nuon DVD systems with a handful of N64-ish looking games. Certainly not an Mario/N64 killer.
The Pyramid 3D TR25201 was the flagship with its geometry processor. TR25202, TR25203 and TR25204 were progressively less capable. Without all the problems I guess TriTech might've had perhaps a 12-18 month head start on Nvidia's NV10 (GeForce 256).
Funny how often that turns out to be the case when something is announced as a so-called "<NOUN> killer".
I can't honestly think of one thing labeled as such that's gone on to do that. Unless someone wants something to fail, nobody should use that phrase.
