• Comparison of 3-D display formats for CAD applications 

      McWhorter, Shane William; Hodges, Larry F.; Rodriguez, Walter E. (Georgia Institute of Technology, 1991)
      Two experiments were performed to rank different types of display formats common to CAD applications in terms of geometric information conveyed and perceived realism of objects. Display types tested were: wireframe, wireframe ...
    • 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 ...
