Modelagem processual como ferramenta propositiva: o software esri cityengine e a regulação urbana

Abstract

How to qualify the built urban form if it is mostly composed of private buildings and therefore hardly influenced by public urban designs, especially in consolidated urban fabric? To progress in this challenge, we propose a reflection on the current urban rules and the traditional planning. Given the rigidity of the traditional methods of establishing urban occupation indexes, the main objective of this study is to assess the relevance of a flexible methodology - using parameter-based measurement and prescription of urban form, employed in procedural urban modeling software - to think over the mechanisms of territorial regulation. As a tool to actualize this method we chose to use the Esri CityEngineTM, tridimensional modeling software specialized in urban environment generation from a set of predefined rules. His procedural methodology - through a programming language called CGA (Computer Generated Architecture) - allows you to change the rules and urban indicators as necessary to make room for new design possibilities. Using the software, we modeled three scenarios: two analytical ones, illustrating the existing situation and the neighborhood's current legislation application and an alternative design exercise from the elaboration of different sets of CityEngineTM rules and their application on buildable areas.
