@OutofPrintArchive@mstdn.games Interesting. I thought they merely made the appearances of things mimic 3D graphics. At the time I thought it was silly that they would try to mimic 3D on 2D. It seems they actually used SGI systems to make them in 3D, then produced the 2D sprites from the renders. That's actually a lot more effort and detail than I ever knew and I now feel bad for looking down on them for that, lol.
As a side note, those wireframes show quite a lot more polys than I would have expected from the time period. SGI systems truly were impressive for their time.
