A vector drawing is simply a drawing made up of geometrical primitives, such as points, lines, curves and polygons, which are all based upon mathematical equations. This is in contrast to raster graphics, which represent images as a collection of pixels (dots)

Footnote 2

A convex space can be defined as a space in which all points can be joined to all others without passing outside the boundary of the space (Hillier cited in Karimi 1998, 64. Footnote 10)

Footnote 3

A detailed explanation of the calculations behind space syntax and the validation of the theory can be found in the following publications: Hillier and Hanson 1984; Hillier et al. 1987; Hillier et al. 1993; Penn et al. 1998; Hillier 1999; Penn 2003; Hillier 2005; Turner et al. 2005
