Researchers at the University of North Carolina at Charlotte and the University of Florida developed the Procedural Shape Modeling Language (PSML) to generate 3D models exclusively from volumetric elements, enabling explicit labeling and querying of both solid and void spaces. This system creates semantically rich models suitable for applications like physical simulations and detailed architectural analysis, as demonstrated by models of an office building, a medieval castle gate, and a Gothic cathedral.
Key insights
- Integrating sequential programming logic directly with non-sequential shape grammar rules within PSML allows for complex context-sensitive behaviors and efficient post-processing, overcoming limitations of decoupled scripting.
- The explicit representation and labeling of void spaces is critical for detailed volumetric analysis, spatial reasoning, and enabling dynamic, context-sensitive model generation, such as placing doors based on intersecting empty spaces.
- An object-oriented design, modular grammars, and external attribute files in PSML enhance reusability, foster collaborative model development, and make procedural generation more accessible to non-programmers.
