Computer Graphics
Subject Overview
Computer Graphics covers display technologies and 2D primitives (line, circle and ellipse scan-conversion algorithms), 2D transformations and viewing, clipping and filling techniques, and 3D object representation and rendering including visible-surface determination and shading models like Phong's and Gouraud shading. A 4-credit core theory paper.
