    • Surface Relief Analysis for Illustrative Shading 

      Ammann, Lucas; Barla, Pascal; Guennebaud, Gaël; Granier, Xavier; Reuter, Patrick (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this paper, we present an analysis technique that leverages the complexity found in detailed 3D models for illustrative shading purposes. Given a smooth base surface with relief, it locates relief features (concavities, ...

    • Tessellation-Independent Smooth Shadow Boundaries 

      Mattausch, Oliver; Scherzer, Daniel; Wimmer, Michael; Igarashi, Takeo (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We propose an efficient and light-weight solution for rendering smooth shadow boundaries that do not reveal the tessellation of the shadow-casting geometry. Our algorithm reconstructs the smooth contours of the underlying ...
