Students work at the intersection of Architecture and Game Design to explore the advantages of involving non-experts in the design process. Students will be introduced to the concept of shape grammars — collections of visually defined, geometric rules used to automate the generation of formal representations of designs for buildings and cities. Each student extracts the essential elements of an existing building and models them as a shape grammar in Minecraft. Students document the combination that other players create using these elements and compare them to the original building. Students will develop the following skills: Understanding an architectural design down to its essential elements; Using concepts and tools for combinatorial modelling in a real design task; Visualising design features with simple diagrams.
