WebSmooth Feature Lines on Surface Meshes Goal of this project. In this project, the author will implement an algorithm to extract feature lines of 3D objects. The algorithm is described in Smooth Feature Lines on Surface Meshes. The author will construct a discrete … WebFeature lines are salient surface characteristics. Their definition involves third and fourth order surface derivatives. This often yields to unpleasantly rough and squiggly feature lines since third order derivatives are highly sensitive against unwanted surface noise. The present work proposes two novel concepts for a more stable algorithm producing visually … Web1 Apr 2009 · The feature line extraction, which extracts smooth feature lines from arbitrary objects in a very simple way. The base mesh construction which is (1) independent of the connectivity of the target surface, (2) correct even for complex topology and (3) adapted to the anisotropy of the target object. pa county records
