Sketch based 3D modeling with curvature classification Academic Article

abstract

• In this paper, we introduce a simple method for sketching 3D models in arbitrary topology. Using this method, we have developed a system to convert silhouette sketches to 3D meshes that mostly consists of quadrilaterals and 4-valent vertices. Because of their regular structures, these 3D meshes can effectively be smoothed using Catmull-Clark subdivision. Our method is based on the identification of corresponding points on a set of input curves. Using the structure of correspondences on the curves, we partition curves into junction, cap and tubular regions and construct mostly quadrilateral meshes using this partitioning. 2012 Elsevier Ltd.
