Abstract: This document has four purposes. It is a tutorial in parametric curve and surface representations, it describes a number of algorithms for generating both shaded and line-drawn pictures of bivariate surfaces and trivariate volumes, it explicitly gives transformations between all of the widely used curve and surface representations, and it proposes a solution to the problem of displaying the results of three-dimensional flow-field calculations.
