Phong‐Rodrigues Extrinsic Vector‐Field Processing

Computer Graphics Forum, EarlyView.
Abstract We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporting pointwise evaluation and integration of differential operators.

Circles of Confidence for Multi‐Label Geometry Completion

Computer Graphics Forum, EarlyView.
Abstract Inside–outside classification is widely used for geometry processing tasks such as surface reconstruction, geometry completion, and calculating signed distance fields. We introduce a new integral formulation of this problem, which assigns confidence scores that points are inside or outside, given incomplete boundary geometry.

Meshing Unsigned Distance Fields with Regular Triangulations

Computer Graphics Forum, EarlyView.
Abstract Unsigned distance fields (UDF) are a versatile, implicit representation of geometry. They can represent surfaces that are not bounding a solid or contain points or curves that are not manifold, for example several sheets meeting along a common curve. Contouring the implicit representation, i.e. turning it into an explicit one, requires finding

Alternating Spatial‐Temporal Optimization for Continuous Collision Detection of Signed Distance Fields

Computer Graphics Forum, EarlyView.
Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

SharpEdge: Edge Feature Surface Reconstruction From Space Curves

Computer Graphics Forum, EarlyView.
SharpEdge reconstructs surfaces with sharp features from sparse 3D curve networks. By estimating dual normals along curves, our method preserves ridges and corners while producing high‐quality meshes. Abstract Reconstructing high‐quality surfaces from sparse 3D space curves remains challenging, particularly when sharp feature edges are involved ...

Morphology‐based phylogeny of longhorn beetles (Coleoptera, Cerambycidae) aligns with phylogenomics and informs higher‐level systematics

Cladistics, EarlyView.
Abstract We present a morphology‐based backbone phylogeny of Cerambycidae beetles inferred by parsimony analyses using 77 adult characters scored for 101 species. This phylogeny is largely consistent with recent phylogenomic studies regarding key placements (e.g., Parandrini stat. rev. within Prioninae, Necydalini stat. rev.

Integrated species distribution modeling to assess species status and current and future threats for an imperiled amphibian

Conservation Science and Practice, EarlyView.
To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Pairing ecological modeling and human dimensions in structured decision making: Road management for a declining species

Conservation Science and Practice, EarlyView.
Structured decision making (SDM) is an effective framework for addressing complex natural resource problems, but few applications have incorporated substantive social science—particularly, human dimensions methods—to more fully characterize socioecological components of these problems. We describe an SDM process that paired ecological models with human

Comparison of computed tomographic, radiographic and anatomical dorsal hoof wall measurements

Equine Veterinary Education, EarlyView.
Summary Background No comparison of radiographic and computed tomographic (CT) dorsal hoof wall (DHW) thickness and DHW to the palmar length of the distal phalanx (DHWDP) ratio has been published. Radiographic measurements obtained with and without radiodense markers on the DHW have not been compared.
