چکیده:
3D modeling and visualization in large-scale cities is a major difficulty for computer graphics. Studying photos of a big city reveals a variety of street patterns, buildings, shapes, and textures. This paper presents "procedural modeling" as a new approach to create three-dimensional modeling, especially for large-scale modeling. Procedural modeling deals with the production of semi-automatic (semi) content using a program or routine. This kind of modeling was historically utilized for 3D visualizing the natural properties, however, by releasing the CityEngine in 2008, the technology can easily be applied to urban environments as well. In this paper, this approach using a descriptive-analytical method will be examined, with particular emphasis on the extent to which procedural modeling is used in the design of cities, streets, buildings, etc., by CityEngine software. Therefore, while reviewing how architectural form grammars are used to generate 3D modeling procedures, two types of modeling including traditional and procedural modeling will be studied and compared and the benefits of procedural modeling will be revealed. After a description of the features of CityEngine, it will be introduced as a technique that follows procedural modeling. Finally, due to the advantages of procedural modeling, this type of modeling (algorithmic) is suggested as an alternative to manual modeling (traditional methods in urban design) to increase the accuracy, speed, and efficiency of the design and in addition, this will increase the flexibility of the design via this approach. In this regard, the workflow of the procedural modeling process will be provided using the CityEngine technique and a number of outputs of this technique that have been provided in the CGA will be presented.
