Author here. I wanted to share this piece of personal and technical history from the early days of 3D graphics. The article covers the meeting on my houseboat with Jensen, Curtis, and Chris in 1993, working on biquadratic texture mapping for the NV1, and how Microsoft’s sudden pivot to triangles in DirectX nearly broke the company before their pivot to the RIVA 128. It also digs into the paperwork anomaly I recently uncovered regarding my Technical Advisory Board options and the vesting schedule. Happy to answer any technical questions about the early 90s VR/graphics scene or the NV1 era!

You lived on a houseboat named SS Vallejo in Sausalito...

Any chance it was THE Vallejo where Alan Watts lived, and the grateful dead once played? Or maybe she was just named in homage?

Either way, it's very cool! Thanks for the great read.

Quads and biquadratic texture mapping truly were an awful choice and it's incredible that the company still pulled through. I have an NV1 floating around somewhere; I should dust it off again.

I'm familiar enough with the history, but I really have to wonder why quads were pursued. It seems like even at the time, triangles were the obvious long-term bet. Of course it's never quite that obvious at the time, but nevertheless quads seem like one of those weird tech offshoots that are simply too different to ever get traction, like ternary arithmetic. And the trajectory of transistor counts was such that per-pixel division for perfect perspective correctness was simply inevitable.

I was in on the ground floor of WiFi, in that around 1995 I did a significant chuck of the work that proved that WiFi works, and my work at a university lead to the formation of a company that put WiFi into the market (Radiata). The IP situation was murky. A patent holder made about $1b and the company sold for $560m (in 2000). I gather the university complained and got a good chunk of "go away" money. I could have thrown my hat in the ring: maybe I would have got something, maybe I wouldn't have. Either way, I walked away, as I judged it wasn't worth the non-financial cost. 30 years layer I still think I made the right decision. I might have been living in a nicer house, but I wouldn't have the life I have today, which I am happy with.

I don't know your situation in life, but if your experience is anything like mine I reckon you've probably made the right decision.

In 1989 I was consulting for a large company in NYC that hired you to give our small UI/UX team a demo of your VR system. I still remember strapping on the headset and looking around the virtual world. I might even have your business card somewhere!

Do you still program for fun ?

I’m in a small game dev group and I very much enjoy seeing how older engineers tackle problems.

What was your gain on the 15,625 shares you did own? What year did you sell them?

How bad was the motion sickness back then and what kind of hardware were people using for the headsets?

Did anything progress past tech demos?

The Kingdom of Tonga stood out to me. Are you still there? Why were you there? It's a very interesting place, especially for anyone not from there. I'm only adjacently aware as someone who spent most of my life in a different Polynesian country.
