By retro platform GP meant Atari ST and Commodore Amiga and the like: LUT were the name of the game for everything back then. Games, intros/cracktros/demos. Heck even sprites movements often weren't done using math but using precomputed tables: storing movements in "pixels per frame". It worked particularly well on some platforms because they had relatively big RAM amounts compared to the slow CPU and RAM access weren't as taxing as today (these CPUs didn't have L1/L2/L3 caches). The N64 is already a more modern machine.
