Subdivision Directional Fields [PDF]
ACM Transactions on Graphics, 2019 We present a novel linear subdivision scheme for face-based tangent directional fields on triangle meshes. Our subdivision scheme is based on a novel coordinate-free representation of directional fields as halfedge-based scalar quantities, bridging the ...

Barycentric subdivisions [PDF]
Pacific Journal of Mathematics, 1988 A characterization is given of simplicial polytopes that are barycentric subdivisions of regular CW spheres. It is shown that barycentric subdivisions of connected polyhedral complexes with at least two facets determine the underlying complex uniquely up to duality. Connections with the algorithmic theory of comparability graphs are discussed.

Journal of Graph Theory, 2021 AbstractWe prove that for every graph of maximum degree at most 3 and for every positive integer there is a finite such that every ‐minor contains a subdivision of in which every edge is replaced by a path whose length is divisible by . For the case of cycles we show that for every ‐minor contains a cycle of length divisible by , and observe that ...

ACM Transactions on Graphics, 2020 This paper introduces Neural Subdivision , a novel framework for data-driven coarse-to-fine geometry modeling. During inference, our method takes a coarse triangle mesh as input and recursively subdivides it to a finer geometry by applying the fixed topological updates of Loop Subdivision, but predicting vertex ...

Canonical Möbius subdivision [PDF]
ACM Transactions on Graphics, 2018 We present a novel framework for creating Möbius-invariant subdivision operators with a simple conversion of existing linear subdivision operators. By doing so, we create a wide variety of subdivision surfaces that have properties derived from Möbius geometry; namely, reproducing spheres, circular arcs, and Möbius regularity.

Connectional subdivision of the claustrum: two visuotopic subdivisions in the macaque [PDF]
Frontiers in Systems Neuroscience, 2014 The claustrum is a surprisingly large, sheet-like neuronal structure hidden beneath the inner surface of the neocortex. We found that the portions of the claustrum connected with V4 appear to overlap considerably with those portions connected with other cortical visual areas, including V1, V2, MT, MST and FST, TEO and TE.

Adaptive Subdivision of Catmull-Clark Subdivision Surfaces [PDF]
Computer-Aided Design and Applications, 2005 Catmull-Clark subdivision scheme provides a powerful method for building smooth and complex surfaces. But the number of faces in the uniformly refined meshes increases sharply with respect to subdivision depth. This paper presents an adaptive subdivision technique as a solution to this problem.
