Rather, processing is dependent upon the nature of the archaeological residues and their surrounding matrix, the type of analysis one wants to undertake and the range of ancil

Familiarisation with Programs, Graphics Devices and Primitives,n recent years so much effort has been put into graphics software standards (such as G.K.S. (Hopgood .., 1983)) as well as into the portability of graphics packages (GINO, CalComp etc.). This book will concentrate on the techniques of . and .

Techniques for Manipulating Two-dimensional Objects, and polygonal facets. In this chapter we shall consider a number of techniques which may be used for more complex pictures of two-dimensional scenes along with some which we will need when developing algorithms to deal with three-dimensional solid models. Naturally these routines must be merged int

Three-dimensional Co-ordinate Geometry, Cartesian co-ordinate geometry and introduce some useful procedures for manipulating objects in three-dimensional space. (For further reading we recommend books by Cohn (1961) and McCrae (1953)). As in two-dimensional space, we arbitrarily fix a point in the space, named the . (origin for short). W

Matrix Representation of Transformations in Three-dimensional Space,tep before we are able to proceed to projections of three-dimensional space onto the necessarily two-dimensional graphics viewport. As in the lower dimension, there are three basic transformations: translation of origin, change of scale and axes rotation; we will ignore all other transformations suc

The Observer and the Orthographic Projection,aw how to construct a model of a three-dimensional scene in ACTUAL position. In this chapter we consider observing the scene and the display of a corresponding view. The display of the scene is co-ordinated by routine . which may take a number of different forms, depending on the type of image requi

Generation of Model Data,ene via construction routines, some input from file. Then the vertices are transformed into the OBSERVED position, and the routine . is called to display the scene. In the following chapters we will give a number of different types of . and facet display routines, dependent only on the projection an
