Years prior to starting his Master's thesis, Mathias Plans had developed a procedural generation system using shape grammars for his Bachelor's thesis. Shape grammars are a way of defining formal grammar systems where words are buildings. In his Master's thesis, Mr. Plans built an editor using the Godot game engine so that it would be easy for other people to use his procedural generation workflow. The editor allows the creation of rules based on shape editing. The rules can be iterated on. The suitable result can be exported as an STL file. The grammar itself can be imported directly to Godot through a plugin developed by Mr. Plans.
