Operator were proposed by Taubin and by Hildebrandt and Polthier. That this is an active area of research, and new methods for computing differential Latter is similar but not identical to the method discussed in Sect. Small curvature variations may not be obviousįrom a shaded rendition of 3D model but are easy to detect if the curvature is mappedĪ related area is non-photorealistic rendering which is concerned with the The most obvious application of curvature measures on triangle meshes is simply Geometric properties of meshes still appear. In some cases, we wish to improve a triangulation while maintaining the vertices Very often these strokes are aligned with the directions of min or max Is “hatching” where the artist draws strokes in order to enhance shape and One artistic style that has been simulated Ren-dering of 3D models in an artistic fashion. The most popular way of doing this is by edge flipping. The edge sharedīy two adjacent triangles can be replaced by a transverse edge. This means that some energyįunction is required, and an effective choice is the integral absolute mean curvature Loop over all edges and flip if it reduces some energy.
