Texture mapping
True real-time 3D rendering using polygons were soon popularized by Yu Suzuki's Sega AM2 games "Virtua Racing" (1992) and "Virtua Fighter" (1993), both running on the Sega Model 1 arcade system board; some of the Sony Computer Entertainment (SCE) staff involved in the creation of the original PlayStation video game console credit "Virtua Fighter" as inspiration for the PlayStation's 3D graphics hardware. According to SCE's former producer Ryoji Akagawa and chairman Shigeo Maruyama, the PlayStation was originally being considered as a 2D-focused hardware, and it wasn't until the success of "Virtua Fighter" in the arcades that they decided to design the PlayStation as a 3D-focused hardware. Texture mapping and texture filtering were soon popularized by 3D racing and fighting games.
