  • Title: Edge-based identification of DP-features on free-form solids.
    Author: Lim T, Medellin H, Torres-Sanchez C, Corney JR, Ritchie JM, Davies JB.
    Journal: IEEE Trans Pattern Anal Mach Intell; 2005 Jun; 27(6):851-60. PubMed ID: 15943418.
    Abstract:
    Numerous applications in mechanical CAD/CAM need robust algorithms for the identification of protrusion and depression features (DP-features) on geometric models with free-form (B-Spline) surfaces. This paper reports a partitioning algorithm that first identifies the boundary edges of DP-features and then creates a surface patch to cover the depressions or isolate the protrusions. The novelty of the method lies in the use of tangent continuity between edge segments to identify DP-feature boundaries that cross multiple faces and geometries.
