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 ...

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.

Large landscape conservation partnerships: A social network analysis of the Appalachian Trail landscape

Conservation Science and Practice, EarlyView.
Using social network analysis, this study examines the structure of conservation partnerships in the Appalachian Trail Landscape, focusing on how organizational characteristics shape network centrality and roles. Results reveal a large, low‐density network with a modest core‐periphery structure, where natural resource agencies and conservation non ...

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

Ibis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

A likely role for stratification in long-term changes of the global ocean tides

Communications Earth & Environment
Stratification—that is, the vertical change in seawater density—exerts a subtle control on the energetics and thus the surface elevation of barotropic (depth independent) flows in the ocean. Changes in stratification therefore provide a plausible pathway

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

Insect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide
