Computing Smooth Surface Contours with Accurate Topology Pierre Benard, Aaron Hertzmann, Michael Kass March 2014 This paper introduces a method for accurately computing the visible contours of a smooth 3D surface for stylization. This is a surprisingly difficult problem, and previous methods are prone to topological errors, such as gaps in the outline. Our approach is to generate, for each viewpoint, a new triangle mesh with contours that are topologically-equivalent ... [more] To appear in ACM Transactions on Graphics |
