The tools of representation and communication in architectural design and practice are not simply neutral vehicles but rather active agents that occasionally constrain as well as catalyze certain design outcomes and modes of design thinking. This relationship leads to cumulative influences that slowly change the very nature of design process, products, professional organisation and discourse in design.This book traces imaging techniques in architecture from antiquity to the contemporary age of digital media, looking at the development and adoption of various instruments of imagination in architectural history from humble paper and wood models to today's hi-tech digital tools. The book has a fresh historical perspective on the notion of instrumented imagination, a theme that is expected to increasingly occupy both theoreticians and practitioners in the coming decades.
