ABSTRACT
This chapter introduces the second part of the book. Part 2 presents two categories of new tools and techniques that draw directly upon digital geometry and technology to foster speculations upon the generation of architectural form. The first category, discussed in this chapter, consists of digital drawings that use existing visioning technologies and open-source digital software to re-present urban image data as atmospheric spatial representations. This chapter outlines how the functionality of software traditionally used for biological image analysis can be adapted to assess spatial transitions and transformations within images across selected timeframes. It reveals how the pixel's structural capacity to embed complex numerical data about an object's colour, brightness and shape means that the atmospheric qualities of any captured scene are the determining factors of digital image composition. The chapter argues that the revelation and presentation of these qualitative urban conditions present a new mode of disciplinary drawing and design practice.
