Both SGI (who had no hardware texture mapping at the time) and 3dfx were explored at the time DARPA SIMNET was being developed. Delta Graphics (Mike Cyrus' and Jay Beck's company - of the Cyrus-Beck line clipping algorithm fame), which did have hardware Z-buffer texture-mapping, were the incumbents, and was fielded. Gary Tarroli personally visited BBN for a chat, but I wasn't involved in that. If Abort-Retry-Fail is interested in the history of SIMNET (in addition to the first hardware texture-mapping fielded, first AI NPC, etc.), there is a lot of info available. Email me and I can provide the info.
