Procedural modeling as a practical technique for 3D assessment in urban design via city engine

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and procedural modeling and consider the advantages of procedural modeling. furthermore, reviewed the features of CityEngine software and introduced CityEngine as a software application that uses the procedural modeling system. Procedural modeling deals with (semi-)automatic content generation by means of a program or procedure. We survey procedural methods that are useful to design roads, buildings, and entire cities. In this survey, we focus particularly on the degree of the use of procedural modeling in the design of cities, streets, buildings, etc, in by CityEngine software. This paper examines how architectural shape grammars can be used to procedurally generate 3D modeling. In the end, considering the advantages of the procedural modeling, we propose procedural modeling (Algorithmically) to replace the manual modeling (Traditional methods) to increase the accuracy, speed, and design efficiency, furthermore, the flexibility of this approach helps to quickly change and regenerate the model as a new model.
