In contemporary 3-dimensional computer graphics, the graphics pipeline consists of a sequence of affine transformations composed at the end with a single perspective projection. Typically, affine and projective transformations are represented by 4׳4 matrices, and 3-dimensional points and vectors are represented with four homogeneous coordinates. In this framework, quadric surfaces are also usually modeled by (symmetric) 4׳4 matrices. Recently, however, several authors (Dorst, Mann, Fontijne, Hildenbrand, Perwass, Rockwood, Vince) have suggested that Clifford algebra might ...
