Yeah, I wrote a set of 3D demos for Acorn, to showcase the new RiscPC at Acorn World '94. There was a landscape flyover and a virtual textured talking head. All rendering was done entirely in software of course, using integer maths. I developed a type of Bresenham's Algorithm to trace the hyperbolic curves in texture UV space that translate to scanlines, when one is doing perspective correct texture mapping.
Subsequently I wrote a sample implementation of the Xerox Rooms paradigm for Acorn. It was a 3D office environment, with clickable destinations that would "teleport you" into new spaces. I'm not sure what became of this though tbh.
Next they wanted me to write a version of SGI's GL API for RiscOS, however - for whatever reason that project never really got started, so I had to go and get a proper job! :-(
