Abstract: In the early days of Computer Graphics primary attention had to be given to the mathematics of simple geometric elements like points, lines and planes Homogeneous coordinates and space transformation using matrices also received considerable attention This is much less true today, since most of this mathematics has now become standard, is available in most computer graphics texts, is usually incorporated as part of many of the available graphics software packages and is even being incorporated into some of the more sophisticated graphics workstation processors In this tutorial therefore the emphasis has been shifted to the mathematics of more complex geometric entities such as polygonal regions, curves and surfaces Emphasis has also been placed on algorithms for processing these shapes and in particular generating various kinds of images of these geometric shapes

Abstract: The RealityEngine graphics system is the first of a new generation of systems designed primarily to render texture mapped, antialiased polygons. This paper describes the architecture of the RealityEngine graphics system, then justifies some of the decisions made during its design. The implementation is near-massively parallel, employing 353 independent processors in its fullest configuration, resulting in a measured fill rate of over 240 million antialiased, texture-mapped pixels per second. Rendering performance exceeds 1 million antialiased, texture mapped triangles per second. In addition to supporting the functions required of a general purpose, high-end graphics workstation, the system enables realtime, “out-the-window” image generation and interactive image processing.
