A new general-purpose technique for the visualization of time-dependent Symmetric positive definite tensor fields of rank two is described. It is based on a splatting technique that is built from tiny transparent glyph primitives which are capable of incorporating the full directional information content of a tensor. The result is an information-rich image that allows to read off the preferred directions in a tensor field. It is useful for analyzing slices or volumes of a three-dimensional… 

Superquadric Glyphs for Symmetric Second-Order Tensors

This work generalizes a previous method of superquadric glyphs for positive-definite tensors by drawing upon a larger portion of the superquadrics shape space, supplemented with a coloring that indicates the tensor's quadratic form.

Diffusion Tensor Visualization with Glyph Packing

This work adapt particle systems originally developed for surface modeling and anisotropic mesh generation to enhance the utility of glyph-based tensor visualizations, by carefully distributing glyphs throughout the field into a dense packing.

A hybrid visualization technique in which hyperstreamlines and elliptical glyphs are used in real and complex domains, respectively, which enables a more faithful representation of flow behaviors inside complex domains and leads to an efficient tensor field visualization system for domain scientists.

An Evaluation of Glyph Perception for Real Symmetric Traceless Tensor Properties

A perceptual study of four tensor glyphs for symmetric, real, traceless tensors was performed to evaluate the effectiveness of visually communicating the properties and discusses the significant differences found between the methods as guidance to the use of these Glyphs for trACeless tensor visualization.

This review focuses on second‐order tensors that are not diffusion tensors, and discusses the strengths and limitations of existing methods when dealing with such tensors as well as challenges introduced by them.

Hybrid visualization of asymmetric tensor fields : glyphs and hyperstreamlines

A hybrid visualization approach in which hyperstreamlines are used to illustrate the tensors in the real domains and glyphs are employed in complex domains and this enables an effective visualization of the physical patterns everywhere and also provides a more intuitive illustration of elliptical patterns in the complex domains.

Asymmetric tensor visualization with glyph and hyperstreamline placement on 2D manifolds
