Procedural generation of buildings in Blender using geometry nodes

Cilj ovog rada bio je napraviti Blender aplikaciju koja omogućuje proceduralno generiranje građevina koristeći geometrijske čvorove. Za stvaranje programskog rješenja korišten je priključak Open Street Map (OSM) i Quixel bridge aplikacija za uvoz 3D modela iz internetske baze podataka Megascans. Za proceduralno generiranje zgrada korištena je Blender aplikacija Buildify te je po uzoru na nju ugrađena funkcionalnost proceduralnog generiranja mostova. U korisničko sučelje izloženi su parametri koji mijenjaju svojstva generiranih objekata kako bi se olakšala njihova izmjena, odnosno kako bi bila moguća bez otvaranja i promjene postavki geometrijskih čvorova. Generiranje gradova omogućeno je integracijom OSM-a. Pri testiranju aplikacije potrebno je pravilno postaviti dimenzije objekata koji se koriste kako bi se postigli željeni rezultati. Aplikaciju je moguće proširiti dodavanjem podrške za rad sa zgradama kompleksnih oblika.The goal of this project was to create a Blender application which allows procedural generation of buildings using geometry nodes. Open Street Map (OSM) was a plug-in used in creation of this application, as well as the Quixel bridge application used for importing 3D models from a network library called Megascans. A blender application Buildify was used to enable procedural generation of buildings and, by its example, the function to procedurally generate bridges was added. Parameters which alter the properties of buildings are presented in the user interface in order to make their customization easier, precisely, making it possible without having to open the geometry nodes setup. City rendering was enabled by the use of the OSM plug-in. While testing this application, it's necessary to set the proper dimensions of objects used in order to ensure good results. It is possible to extend the application by adding support for working with buildings of complex shapes
