Volumetric procedural models for shape representation

This article describes a volumetric approach for procedural shape modeling and new Procedural Shape Modeling Language (PSML) that facilitates the specification of these models. PSML provides programmers ability to describe shapes in terms their 3D elements where each element may be semantic group objects, e.g., brick wall, or an indivisible object, individual brick. this manner creation models more closely approximate organization structure real-world counterparts. As such, users query information such as number, position, orientation volume which cannot provided using surface based model-building techniques. also number language-specific capabilities allow rich variety context-sensitive behaviors post-processing functions. These include object-oriented model design, methods querying component-based access components perform Boolean operations on parts. is open-source includes freely available tutorial videos, demonstration code integrated development environment support writing programs.
