Shortest Path Problems on a Polyhedral Surface [PDF]

open access: yesAlgorithmica, 2009
We develop algorithms to compute edge sequences, Voronoi diagrams, shortest path maps, the Fréchet distance, and the diameter for a polyhedral surface. Distances on the surface are measured either by the length of a Euclidean shortest path or by link distance. Our main result is a linear-factor speedup for computing all shortest path edge sequences on

Facility Location on a Polyhedral Surface [PDF]

open access: yesDiscrete and Computational Geometry, 2003
This paper considers the Euclidean 1-center problem on a polyhedral surface: Given an orientable genus-0 polyhedral 2-surface defined by \(n\) triangles, and a set of \(m\) sites on it, identify a location on the surface that minimizes the maximum geodesic distance to the sites.

Polyhedral Surface: Self-supervised Point Cloud Reconstruction Based on Polyhedral Surface [PDF]

open access: yesCoRR, 2023
Point cloud reconstruction from raw point cloud has been an important topic in computer graphics for decades, especially due to its high demand in modeling and rendering applications. An important way to solve this problem is establishing a local geometry to fit the local curve.

Pursuit Evasion on Polyhedral Surfaces [PDF]

open access: yesAlgorithmica, 2013
The authors consider a discrete-time pursuit-evasion game played on the surface of a 3-dimensional polyhedron. Play alternates between a team of pursuers and a single evader. On the pursuers' turn, all pursuers may simultaneously move a distance of up to 1 on the surface; on the evader's turn, they may likewise move up to 1 unit away from their current

Discrete Yamabe Problem for Polyhedral Surfaces

open access: yesDiscrete & Computational Geometry, 2023
AbstractWe study a new discretization of the Gaussian curvature for polyhedral surfaces. This discrete Gaussian curvature is defined on each conical singularity of a polyhedral surface as the quotient of the angle defect and the area of the Voronoi cell corresponding to the singularity.

Data-Driven Modeling of Composition-Processing-Microstructure Relations for Recycled Aluminum Cast Alloys. [PDF]

open access: yesAdv Sci (Weinh)
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Construction of Quasi-Ordered Metal-Organic Frameworks Superstructures via Colloidal Assembly of Anisotropic Particles for Selective Organic Vapor Sensing

open access: yesNanomaterials, 2023
Colloidal assembly of anisotropic particles holds great promise for achieving diverse packing geometries and unique photonic properties. One intriguing candidate for anisotropic self-assembly is colloidal metal-organic frameworks (MOFs), which possess ...

Visual smoothness of polyhedral surfaces [PDF]

open access: yesACM Transactions on Graphics, 2019
Representing smooth geometric shapes by polyhedral meshes can be quite difficult in situations where the variation of edges and face normals is prominently visible. Especially problematic are saddle-shaped areas of the mesh, where typical vertices with six incident edges are ill suited to emulate the more symmetric smooth situation. The importance of a
