Accurate and robust vertex placement for edge collapses

This paper compares two popular layout strategies, one based on the extraction of a spanning tree, the other based on edge crossing minimization of directed acyclic graphs..

Our approach targets the elimination of poorly-shaped elements while simplifying the model using edge collapses and other mesh operations, such as vertex smoothing, tetrahedral

We examine the effect of such operations on a 3D simplicial complex, and we describe algorithms for edge collapse and vertex split on a compact representation of a 3D

The refinement pro- ceeds by subjecting NLD edges to an edge split, which inserts a new vertex along an original edge of the input mesh and con- nects the newly inserted vertex with

Additionally, if we have a vertex of type 2.3 or 2.4 we generate a new spike bisector induced by the site event edge and the intersected edge of the wavefront and insert

Based on the operation tree, the model can be continuously adapted using parallel vertex split and edge collapse operations.. Our proposed algorithm can be divided in two

Given the virtual source information per face, geodesic distances can be reconstructed on the entire mesh with considerably higher accuracy than plain linear interpolation of
