22 Conceptualised diagram showing key elements in a vector graphics display system. The display list stores the coordinate values that are needed to create the lines and polylines on the display screen together with illumination and colour information (not indicated in the illustration). As may be seen, the starting coordinates of the first line within a polyline are supplied and the end coordinates for all other line segments (other than the last in the polyline) can be deduced. An additional final entry for each polyline (x end ,y end ) indicates the end coordinates of the last vector to be drawn.

8(b)). Contrasting the contribution of Alberti with that of Piero, Boyer [1991] writes: ‘ . . 14 to produce a view that employs three vanishing points. Over the subsequent years, techniques such as those described by Alberti coupled with an understanding of ways in which shading and colour can be effectively employed ultimately enabled photorealistic renditions of 3-D scenes to be created on the 2-D tableau. By drawing on the techniques that have evolved, the artist can transcend and surpass photorealism – the world created by the artist embracing both imagination and emotion: ‘The artist is responsible for every detail depicted on the canvas – the finished work represents the coalescence of the artist’s ability to accurately observe a 3-D scene and to properly map these observations onto a 2-D space.

18 The formation of a perspective view as described by Parker and Wallis in their 1948 publication (it appears that this work was carried out several years before their paper was published). Despite the poor quality of the photograph, the volume indicated (which corresponds the region swept-out by a ‘rectangular’ radar scan) may be seen together with two reference planes and a pair of cross-wires. By means of controls provided within the analogue calculation system (used to form the perspective view) the image depicted on the screen could be rotated and so the volume could be observed from different vantage points.
