Origins Of Computational Design In Architecture, Ossama Mohamed Al-Rawi

Future Engineering Journal

The changes that the computer is bringing to architecture are one part of a revolutionary social upheaval. Tools not only change individual patterns and behaviour, but also cause transformations in institutions. Just as other tools have in the past, the computer is in the process of conditioning our understanding of the world and our perception of our place in it. The application of computers to architecture is more than anew sophisticated tool that can be manipulated like a pencil or pen. It is rather, “the culmination of the objectifying mentality of modernity and it is, therefore, inherently perspectival. The tyranny …
