by Dinesh Thakur Category: Two Dimensional Transformations

An algorithm employed in 3D GRAPHICS to fool the eye into seeing as a smoothly curving surface an object that is actually constructed from a mesh of polygons. Gouraud's algorithm requires the colour at each vertex of a polygon to be supplied as data, from which it INTERPOLATES the colour of every PIXEL inside the polygon: this is a relatively fast procedure, and may be made faster still if implemented in a hardware GRAPHICS ACCELERATOR chip.
