   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!

      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?

         Frame rates were low because of limited rendering speed and tracker lag. I did a lot of VR demos starting in 1989 at Autodesk. Not much motion sickness, perhaps 2% of users. The first HMD we used at Sense8 was by Virtual Research (Bruce Bassett) with LEEP optics. And I just found out that John Ternus worked for Bruce. Small planet.

            Beyond tech demos, yes, lots of customers of the WorldToolKit product. From NASA to artist Jenny Holzer. Sense8 was acquired in 1998 by Engineering Animation.
