Tiivistelmä
3D modelling for film and video game productions is a time-consuming task, especially if the goal is to create large-scale environments like cities, with thousands of buildings or natural environments with intricate organic details. This is why these kinds of modelling tasks are often automated through procedural techniques instead of using strictly manual methods.
The free open-source 3D software Blender introduced Geometry Nodes in version 2.93 as a tool for procedural modelling through a node-based user interface. The aim of this thesis was to evaluate Geometry Nodes by looking at how well it delivers the benefits of procedural modelling methods. The benefits of procedural modelling were studied by examining previous practical use-cases. After this, Geometry Nodes was tested in the modelling process of a short film production.
The practical case-study resulted in two procedural environment assets for the author’s short-film “Product 21”. The thesis concluded that Geometry Nodes was a useful and powerful tool in achieving the desired results while being approachable with its visual programming interface. It was also found that there are more potential use-cases in the production that were not addressed in this experiment. Certain obstacles and challenges occurred in the making of both assets which were deemed as problems that are inherent to procedural methods in general.
