Mass content creation is nowadays one of the most important challenges for game artists. This paper presents a high-level architectural modeling solution that combines the full generative power of shape grammars with the ease of use and flexibility of a node-based visual language. Our approach comprises a shape data flow character and introduces some novel features, including recursion, parametric flow, and flow filtering. The main development model consists of encapsulating basic operations into semantically-rich, reusable components that can be more easily assembled using filters. Eventually, this enables users to concentrate on the more intuitive and interactive development layers, while the text-based grammar rules are automatically generated.
