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.
介绍了一种基于字形的方法来可视化向列型液晶取向张量。与先前的方法不同，该字形基于物理关联的度量，而非特征值的偏移量。这些度量与一组超椭球体形状相结合，既传达了晶体单轴取向的强度，也传达了双轴性的程度。只需进行少量修改，我们的方法就能可视化任何实对称无迹张量。
