Origin: From a proper name. Etymon: proper name Gouraud.

Etymology: < the name of Henri Gouraud, French computer scientist (b. 1944), who devised the model and algorithm (published in 1971 in IEEE Trans. on Computers C-20 623-9).

Computing.

attributive. In computer graphics: designating or relating to a method of modelling the illumination of objects in order to simulate the effects of light and shade across their surface. Esp. in Gouraud shading.

ΚΠ

1975 2nd USA–Japan Computer Conf. Proc. (AFIPS) 475 A method exploiting both Phong and Gouraud shading is offered.

1990 Aerospace Amer. (Nexis) June (Computers & Software section) 44 Shaded images can be created using either Gouraud or Phong lighting models.

1994 Irish Times (Nexis) 6 Aug. (Weekend section) 11 Tie Fighter employs fully light-sourced gouraud shading and this makes everything seem even more realistic.

2004 Game Developer (Nexis) 1 Jan. 18 In games we're so used to crappy Gouraud shading that it's unlikely a small normal error in a 3,000-polygon character mesh will attract much attention.
