摘要: Tensor field visualization is a challenging task due in part to the multi-variate nature of individual tensor samples. Glyphs convey variables by mapping eigenvectors and eigenvalues orientation shape geometric primitive, such as cuboid or ellipsoid. Though widespread, cuboids ellipsoids have problems asymmetry visual ambiguity. Cuboids can display misleading for tensors with underlying rotational symmetry. Ellipsoids differing be confused, from certain viewpoints, because similarities profile shading. This paper addresses ambiguity new tunable continuum glyphs based on superquadric surfaces. Superquadric enjoy necessary symmetry properties ellipsoids, while also imitating cylinders better orientation, where appropriate. The are demonstrated fields diffusion human brain.
