Procedural road generation in 3D modeling simplifies the creation of urban and rural environments. In this work, the student will develop a plugin for the 3D modeling program Blender allowing simplified procedural creation of roads and road systems. The student will research the capabilities of Geometry Nodes (visual language within Blender for geometry generation) and current road generation solutions used in 3D modeling and games. Afterward, the student will design a solution appropriate for Blender environment. This plugin will be implemented in Geometry Nodes and supplemented with GUI implemented using Blender Python API. Within this plugin, the user should be able to select one of pre-made road types or design their own (structure and sizes of road parts: sidewalks, shoulders, median strip). Using a tailor-made GUI, the user should be able to draw a singular road or a road system. Intersecting roads will be contextually merged into crossroads with proper geometry and UV mapping. Additionally, this plugin should enable the user to define road markings and scatter assets (trees, poles, lamps) along the road surface. The work will be carried out in collaboration with the company polygoniq, whose assets - such as models and materials - may also be utilized by the student in completing the task.
