Abstract: We describe an approach to define contours of 3D vector fields and employ them as an interactive flow visualization tool. Although contours are well-defined and commonly used for surfaces and 3D scalar fields, they have no straightforward extension in vector fields. Our approach is to extract and visualize specific stream lines which show the most similar behavior to contours on surfaces. This way, the vector field contours are a particular set of isolated stream line segments that depend on the view direction and few additional parameters. We present an analysis of the usefulness of vector field contours by demonstrating their application to linear vector fields. In order to achieve interactive visualization, we develop an efficient GPU-based implementation for real-time extraction and rendering of vector field contours. We show the potential of our approach by applying it to a number of example data sets.

View-Dependent Streamlines for 3D Vector Fields
TL;DR: This paper introduces a new streamline placement and selection algorithm for 3D vector fields that dynamically determine a set of streamlines which contributes to data understanding without cluttering the view.
A Survey of Seed Placement and Streamline Selection Techniques
TL;DR: This state‐of‐the‐art report analyzes and classify seed placement and streamline selection (SPSS) techniques used by the scientific flow visualization community, and evaluates the identified strategy groups with respect to focus on regions of interest, minimization of redundancy, and overall computational performance.
Fourier Opacity Optimization for Scalable Exploration
TL;DR: This work extends the recent decoupled opacity optimization framework to enable a navigation without occlusion of important features through large geometric data, and studies the quality of the Fourier approximation in terms of accuracy, memory requirements and efficiency for both the opacity computation, as well as the order-independent compositing.

An objective definition of a vortex
TL;DR: In this article, the authors define a vortex as a set of fluid trajectories along which the strain acceleration tensor is indefinite over directions of zero strain, and they show using examples how this vortex criterion outperforms earlier frame-dependent criteria.
Visualizing vector field topology in fluid flows
TL;DR: Methods for automating the analysis and display of vector fieldTopology in general, and flow topology in particular, are described, finding that by using techniques to extract and visualize topological information, it is possible to combine the simplicity of schematic depictions with the quantitative accuracy of curves and surfaces computed directly from the data.

TL;DR: The proposed methodology combines an implicit formulation of curvature with convolution-based reconstruction of the field, and gives concrete guidelines for implementing the methodology, and illustrates the importance of choosing accurate filters for computing derivatives with Convolution.

TL;DR: This paper presents a new evenly-spaced streamlines placement algorithm to visualize 2D steady flows and shows that this method produces images of a quality at least as good as other methods but that it is computationally less expensive and offers a better control on the rendering process.

TL;DR: In this article, a collision detection algorithm for a large number of moving objects with tens of thousands of triangles is presented. But the approach makes no assumption about the input primitives or the object's motion and is directly applicable to all triangulated models.
