Andy Gavin: "[SGI's] stuff from the early '90s was all filled with this giro shading, as it was called, where things all looked like plastic, like colored plast

  Perhaps it was another term for gouraud shading?

    I assumed the name didn't translate if the interview was face-to-face. He did mention using "the shaded mode" instead of the textured mode.

    Almost certainly a transcription error, since "giro" is fairly close to the pronunciation of gouraud.

  Google has five results for "giro shading" and four of them are this article, so I doubt that's a common name. It sounds like he's talking about untextured polygons with smoothing applied to hide the edges; the result tended to look like smooth, shiny plastic, without the usual sharp pixelation of low-res textures and low-poly models. It was definitely a common effect in the early '90s, though I mainly remember it from the N64, particularly Super Mario 64 and similar cartoony mascot games. Edit: Kierenelby is right, he meant "gouraud shading". Here's an example: http://imgur.com/h8vNeaD http://imgur.com/h8vNeaD It's pretty distinctive because a gouraud-shaded ball mostly looks like a sphere, but the outline is clearly polygonal, and the surface highlights follow the otherwise-hidden polygon edges in a weird way.
