Although inconsistent, the connectivity of M and the geometry of N may be combined in a pseudo-manifold representation of N, which exhibits space and performance advantages for many popular applications, especially when N is a triangulated polyhedron. The Matchmaker algorithm introduced here matches ...
Based on such decomposition, we define here a two-level topological data structure for representing non-manifold objects in any dimension: the first level represents components; while the second level represents the connectivity relation among them. The resulting data structure is compact and scalable,...

sampling on the mesh template to generate the connectivity structures for learning. Please use the cmake to create the MakeFile for compiling.Please look at the help in the function to know how to run it. It will take an template mesh and output the sampled connectivity file to the output...
The relevant techniques developed in earlier work are based on generating spanning trees of the face adjacency graph (the graph that represents the connectivity among the faces of the folded structure) since any spanning tree is a potential unfolded flat layout of that structure. However, ...
For this purpose, a special version of a radial edge structure has been constructed by gathering the connectivity information among the topological elements.; During the second phase, the special Boolean operations for Non-manifold Geometries (NMG) have been constructed. This has been accomplished by...
We also propose a new data structure for two-dimensional simplicial meshes, capable of representing both connectivity and adjacency information with a small memory overhead, which is used to describe the mesh extracted from an NMT through selective refinement. Finally, we present algorithms to ...
mesh operates by converting an original (non-manifold) model to a manifold model, encoding the manifold model using a mesh compression technique, and clustering, or stitching together during a decompression process, vertices that were duplicated earlier to faithfully recover the original connectivity. ...

Here, we consider a decomposition of a non-manifold shape into components which are almost manifolds, and we present a novel graph representation which highlights the non-manifold singularities shared by the components as well as their connectivity relations. We describe an algorithm for computing ...
