If you've ever watched any of the "Mind's Eye" CGI videos (which were just older CGI of the 70s, 80s, and some early 90s set to music) - you can get an idea of what your fantasy might look like in full motion.
Most of those old systems and animations didn't use texture mapping and relied on heavier polygon usage, because that's what the hardware could do, while still generating a frame in a reasonable time for transfer to film (still - we aren't talking any kind of "real-time"). While texture mapping was known how to do (sometime in the late 60s or early 70s - can't recall) - doing it with the hardware at the time was extremely slow, so it wasn't used much (IIRC, one of the first CGI films to use it was Sunstone).
Instead, most used hardware that could either do flat-filled polys, or some form of shading (Gouraud, then later Phong). So to make things look good they relied on more detail (more polys and colors) and less on textures (which can hide low-count vertex polys).
The original Tron might also be a good approximation (though from what I recall, it was hand colored from black-and-white computer rendered cels - not sure)...
