We introduce a new approach for procedural modeling. Our main idea is to select shapes using selection-expressions instead of simple string matching used in current state-of-the-art grammars like CGA shape and CGA++. A selection-expression specifies how to select a potentially complex subset of shapes from a shape hierarchy, e.g.

Acknowledgements: We would like to thank Michael Schwarz for developing an initial version of the language and procedural modeling system with us in 2015/2016. He proposed the concepts of virtual, attached, and contained shapes and contributed to the development of the navigation-based selection and constraint handling. He also created Figure 1 and suggested the term selection expression. We also hadmultiple helpful discussions with Peter Rautek and Liangliang Nan about SELEX. Fuzhang Wu helped with the comparison to CGA shape. Further, we would like to acknowledge funding from the Visual Computing Center (VCC) at KAUST through the CARF program and the National Natural Science Foundation of China (61620106003, 61802362, 61772523, and 61331018).
