Computing and visualizing features in fluid flow often depends on the observer, or reference frame, relative to which the input velocity field is given. A desired property of feature detectors is therefore that they are objective, meaning independent of the input reference frame. However, the standard definition of objectivity is only given for Euclidean domains and cannot be applied in curved spaces. We build on methods from mathematical physics and Riemannian geometry to generalize… Expand

Vortex criteria can be objectivized by unsteadiness minimization
Reference frame optimization is a generic framework to calculate a spatially-varying observer field that views an unsteady fluid flow in a reference frame that is as-steady-as-possible. In thisExpand


Time-Dependent Flow seen through Approximate Observer Killing Fields
This work compute a time-dependent observer velocity field that describes the motion of a continuous field of observers adapted to the input flow, corresponding to almost-rigid motion, and proves that theinput flow perceived by the observer field is objective, which makes derived flow features, such as vortices, objective as well.

Discrete Derivatives of Vector Fields on Surfaces -- An Operator Approach
This work considers the problem of computing the Levi-Civita covariant derivative, that is, the tangential component of the standard directional derivative, on triangle meshes, and introduces two linear which provide access to additional constructs in Riemannian geometry that are not easy to discretize otherwise. Expand
Generic objective vortices for flow visualization
This paper proves that in the optimal frame, all local vortex extraction methods that are based on velocity and its derivatives become objective, and demonstrates the approach with objective counterparts to λ2, vorticity and Sujudi-Haimes. Expand
Vector Field Topology of Time-Dependent Flows in a Steady Reference Frame
This work builds up on recent work on vortex extraction to define a time-dependent vector field topology for 2D and 3D flows and compares and discusses the relationships with existing local and integration-based topology extraction methods, showing for instance that separatrices seeded from saddles in the optimal frame align with the Integration-based streakline vector fieldTopology.

An Operator Approach to Tangent Vector Field Processing
This paper argues that vector fields can also be naturally viewed as operators whose domain and range are functions defined on the mesh, and leads to the characterization of vector field properties through commutativity with other operators such as the Laplace‐Beltrami and symmetry operators.

Discrete multiscale vector field decomposition
This paper introduces a variational, multiscale decomposition of vector fields into three intuitive components: a divergence-free part, a curl-free parts, and a harmonic part, and shows how the discrete approach matches its well-known smooth analog, called the Helmotz-Hodge decomposition, and that the resulting computational tools have very intuitive geometric interpretation.

Image space based visualization of unsteady flow on surfaces
The method generates dense representations of time-dependent vector fields with high spatio-temporal correlation using both Lagrangian-Eulerian advection and image based flow visualization as its foundation for direct visualization of unsteady flow on surfaces from computational fluid dynamics.

Flow Charts: Visualization of Vector Fields on Arbitrary Surfaces
A novel flow visualization method called flow charts, which uses a texture atlas approach for the visualization of flows defined over curved surfaces, which allows accurate particle advection across multiple charts in the texture domain, providing a flexible framework that supports various flow visualization techniques.

Using Line Integral Convolution for Flow Visualization: Curvilinear Grids, Variable-Speed Animation, and Unsteady Flows
The algorithm and the animation techniques possible with it are extended to vector fields over curvilinear surfaces, such as those found in computational fluid dynamics simulations, and a technique to visualize vector magnitude as well as vector direction is introduced. Expand
Topology-inspired Galilean invariant vector field analysis
This paper proposes to consider every point as a critical point and locally adjust the frame of reference to the most persistent ones, that means the extrema of the determinant of the Jacobian. Expand
