From Wikia Gaming, your source for walkthroughs, games, guides, and more!

Three-dimensional means having three dimensions, those being height, width, and depths - coincidentally, just like in real life. However, this is different than early Two-and-a-half-dimensional, such as Doom, Duke Nukem 3D, which used advnance mathematical calculations to simulate 3D by rotating or scaling textures to simulate a 3D effect. Even games like F-Zero and Super Mario Kart, while satisfing the requirnments of having height, width, and depths, relied on technologies like Mode 7 for rotating and scaling sprites to simulate "Three Dimensions"

Arguably, three-dimensional video games came into their own with the Sega Saturn/Sony Playstation/Nintendo 64, but there were several Super NES and similar-era games that used technology like an "Super FX chip" (like Star Fox and Super Mario World 2: Yoshi's Island) to achieve grainy 3-D effects.
