    Gouraud Shading

    Concept »

    Gouraud shading is a method of making polygonal objects appear much smoother by applying a gradient to each individual polygon, effectively blending them. Named after Henri Gouraud.

    Short summary describing this concept.

    No recent wiki edits to this page.


    The first video game to use Gouraud shading was Namco's SimDrive in 1992, for their System 22 arcade system. Gouraud shading began gaining popularity in 1993, with Namco's System 22 and Magic Edge arcade systems and Panasonic's 3DO console supporting hardware Gouroud shading, Atari's Jaguar console having partial hardware support for Gouroud shading, and the Origin Systems computer game Strike Commander using software-based Gouraud shading. The technique went on to be used in many other polygonal 3D games of the mid-late 1990s, replacing the earlier flat shading technique.

    In the 21st century, the use of Gouraud shading has declined in favour of Phong shading (named after its creator Bui Tuong Phong), a more advanced form of interpolation technique for surface shading without specular highlight difficulty of Gouraud shading.

    Some of the modern video games that still use Gouraud shading include Capcom's Street Fighter series.
