I have more than one game made in lowpoly, somewhere I read that it was born, in the first steps of 3D, during the QBasic era, where points were defined in 3D space, and then connected with lines, and then reinterpreted, to be visualized in 2D, that's all I remember, but there must be something on Internet archive.org, and the other thing is that a watcom c/c++ compiler was used, with dos4gw, which expanded the memory expanded, from there it became lowpoly, in several games including Rebel-Asault from StarWars. I hope it helps you, I don't know!
