Procedural Generative Design for Spatial Layout Planning Using Hexagonal Cellular Automata

Spatial layout planning in architecture is a complex, highly constrained problem with multiple objectives and wide range of possible solutions. Due to its iterative and time-consuming nature, it is desirable to automate and optimize the spatial layout design process. Here we present a procedural model with hexagonal cellular automata to automatically generate various spatial layouts from basic user inputs of design space, area, and adjacency. The user is also allowed to specify the positions of one or more spaces within the design space. The spatial layout generator can output various 2D models representing the allocated spaces that conform to all the user inputs. It is envisioned that the generated layouts can serve as design guides and alternatives to ease the tedious spatial layout planning process.
