Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Embedding Optimization of Layouts via Distortion Minimization
Computer Graphics Forum, EarlyView.Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

GEODESICS IN LORENTZIAN MANIFOLDS
, 2016 We present an extension of Geodesics in Lorentzian Manifolds (Semi-Riemannian Manifolds or pseudo-Riemannian Manifolds ). A geodesic on a Riemannian manifold is, locally, a length minimizing curve. On the other hand, geodesics in Lorentzian manifolds can

CANRIG: Cross‐Attention Neural Face Rigging with Variable Local Control
Computer Graphics Forum, EarlyView.Abstract Facial animation is one of the most labor‐intensive aspects of animation and VFX, as traditional rigging consumes weeks of expert time and forces animators to spend countless hours manipulating hundreds of controls to achieve varied expressions.

Geometric Linearization of Ordinary Differential Equations
Symmetry, Integrability and Geometry: Methods and Applications, 2007 The linearizability of differential equations was first considered by Lie for scalar second order semi-linear ordinary differential equations. Since then there has been considerable work done on the algebraic classification of linearizable equations and ...

Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications
Computer Graphics Forum, EarlyView.Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

Trapping, chaos and averaging in bubbling AdS spaces
Journal of High Energy PhysicsWe discuss chaos and ensemble averaging in 1/2 BPS bubbling AdS spaces of Lin, Lunin and Maldacena (LLM) by studying trapped and escaping null geodesics and estimating their decay rates.

Individualized Pathfinding in Rugged Open Terrains Using Semantic Navigation Meshes
Computer Graphics Forum, EarlyView.We introduce semantic navigation meshes for complex outdoor terrains, partitioning space into regions with coherent semantic properties like slope or vegetation density. The resulting graphs enable efficient pathfinding with agent‐specific, parameterized cost functions without precomputation, accelerating search while maintaining path quality close to ...

The depth and breadth of capitalism at the Cape
The Economic History Review, EarlyView.Abstract Limited liability company legislation was introduced to the Cape Colony in 1861. An amendment in 1892 led to wider adoption, expanding and diversifying the capital market. Using novel data from the Cape Joint Stock Archive between 1892 and 1902, this paper examines who invested, where capital flowed, and how these patterns shaped firm outcomes

Price and Non‐price Terms of Syndicated Loans to Technology Firms
Financial Management, EarlyView.ABSTRACT This paper examines whether US technology firms receive different price and nonprice terms in the syndicated loan market compared to nontechnology firms. The analysis reveals that technology borrowers face significantly less favorable terms, including 12 basis points higher loan spreads, approximately 5%$\%$ shorter maturities, and loan sizes ...
