Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Polyline Drawings with Topological Constraints [PDF]

, 2018
Let G be a simple topological graph and let Gamma be a polyline drawing of G. We say that Gamma partially preserves the topology of G if it has the same external boundary, the same rotation system, and the same set of crossings as G.

Quantitative Metrics for Edge Bundling of Network Visualizations

Computer Graphics Forum, EarlyView.
Abstract Edge bundling is widely used for reducing visual clutter in large 2D network and trajectory visualizations. Various edge bundling methods have been proposed, each producing qualitatively distinct outputs for the same data; however, few quantitative metrics exist for systematic evaluation. In this paper, we propose a set of quantitative metrics

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.

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 ...

Cell‐Migration Visualization: Task Taxonomy, Systematic Review and Research Agenda

Computer Graphics Forum, EarlyView.
We present an expert‐validated task taxonomy for cell migration analysis and a PRISMA‐based systematic review that maps visualization tools to the tasks they support and the techniques they employ. This synthesis identifies current gaps and outlines opportunities for future research in cell migration visualization.

Bridging Dimensions in STEAM Education: Linking 2D Function Art and 3D Modeling Using GeoGebra

School Science and Mathematics, EarlyView.
ABSTRACT This study examines a constructionist‐oriented STEAM learning activity in which Grade 11 students used GeoGebra 3D to model bridges. Building on prior work in function art, the project extended mathematical art‐making from two‐dimensional representations to three‐dimensional structures, emphasizing the use of functions, geometric ...

Q‐GlaRe+: An Open‐Source Framework for Palaeoglacier Reconstruction and Equilibrium‐Line Altitude Calculation

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Q‐GlaRe+ is an open‐source QGIS plugin for palaeoglacier reconstruction and equilibrium‐line altitude estimation. Validation against Swiss Alpine glaciers demonstrates accuracy comparable to proprietary tools. By removing software barriers and supporting FAIR principles, Q‐GlaRe+ enables broader access to glacier reconstruction capabilities and ...

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...
