Computing has become a recognized art in the discipline of architecture, moving from the periphery towards the core of the design process. Research, education, and application are the critical areas that provide the development platforms for the future of design and computing. Seen in perspective, the term lineamenta describes related activities in historical architectural research. Research also shaped the origins and early directions of CAAD. The first applications emerged after computers and software were powerful enough to implement high level ideas. Meaningful education of a wider audience of designers only became possible after the results of research proved promising.
