Abstract :
A glyph-based method for visualizing the nematic liquid crystal alignment tensor is introduced. Unlike previous approaches, the glyph is based upon physically-linked metrics, not offsets of the eigenvalues. These metrics, combined with a set of superellipsoid shapes, communicate both the strength of the crystal´s uniaxial alignment and the amount of biaxiality. With small modifications, our approach can visualize any real symmetric traceless tensor
