• Multiple Object Selection in Pattern Hierarchies 

      Jang, Justin; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2007)
      Hierarchies of patterns of features, of subassemblies, or of CSG sub-expressions are used in architectural and mechanical CAD to eliminate laborious repetitions from the design process. Yet, often the placement, shape, ...
    • Structured Topological Complexes: A Feature-Based API for Non-Manifold Topologies 

      Rossignac, Jaroslaw R. (Georgia Institute of Technology, 1996)
      Much of recent research in solid modeling was focused on the extension of boundary representation schemes to non-manifold models and, more recently, on the definition of high-level operators for creating such models. We ...
