abstract = "Several applications in visual and geometric computing require the
ability to modify graphical models in such way that geometric
queries or high quality renderings can be generated with great
accuracy. Polygonal meshes are the popular choice of
representation, and several mesh processing operations such as
morphing, level-of-detail or deformation, among others, introduce
challenges on how this task can be performed. A common problem
that arises in such applications is that the result of a mesh
processing operation can either require a costly mesh
re-computation, thus impairing real-time usage, or it requires
constant updates and additional storage to keep several
information required to perform this task. In particular, the
topological information is often harder to maintain updated, since
it is often destroyed or modified during such operations. In this
work we propose a new framework to reconstruct connectivity
information in such way that the quality of the mesh can be
recovered. The connectivity retrieval is accomplished by assigning
weights to the vertices of the triangulation, converting it in a
regular triangulation. Once weights have been computed, the
connectivity can be rebuild by algorithms devoted to construct
regular triangulation. The effectiveness of our new paradigm is
illustrated through two mesh processing applications: mesh
morphing and level-of- detail rendering.",
