The report presents a discussion of existing techniques for representing points, lines, curves, and surfaces within a digital computer, as well as computer software procedures for manipulating and displaying computer output in graphical form. Mathematical techniques for producing axonometric and perspective views are given along with generalized techniques for rotation, translation, and scaling of geometric figures. Curve definition procedures for both explicit and parametric representation are presented for both 2-D and 3-D curves. Curve definition techniques include the use of conic sections, circular arc interpolation, cubic splines, parabolic blending, Bezier curves, and RB sup 3 curves based upon B-splines. Author
