Example text

The results of such analysis, however, generate such large data size as to be nearly incomprehensible. To address this problem, engineers and scientists have turned to visualization. In this chapter we present an overview of engineering analysis techniques, and describe the forms of data that might be expected from such analysis. 1 Introduction The goal of visualizing engineering analysis is an improved understanding of the results of the information generated in that analysis process. It is not difficult to imagine the potential advantages of using advanced visualization methodologies to convert masses of discrete numbers, often measured in gigabits, produced by a numerical analysis procedure into physically meaningful images.

It is now known as ray-tracing, and has been considerably developed and popularized in the 1980s, in particular under the influence of Turner Whitted. The advantages of the approach are that it is conceptually simple and very general as long as one knows how to intersect a primitive with a ray (which is a straight line) inherently modular (each primitive can be dealt with separately), and it is easy to incorporate secondary but important illumination effects such as shadows (by sending a ray towards the light source), reflections and refractions.

Are still the basic modelling primitives of computer graphics. Splines used today are the direct descendents of the mechanical splines used to design ship hulls, and architects from classical Greece to Le Corbusier have tried to design buildings from standard primitive elements. Most of geometry and mathematics was developed in some sense to provide tools for transformation. We will not retrace here the development of perspective, for example (except to note that it was known and practiced substantially before the Renaissance).
