Geometric representation of tensors defined on a domain or set of points. Tensors can be scaled and/or rotated according to the source at eache input point. Scaling and rotation is controlled by the eigenvalues/eigenvectors of the symmetrical part of the tensor as follows:

For each tensor, the eigenvalues (and associated eigenvectors) are sorted to determine the major, medium, and minor eigenvalues/eigenvectors. The eigenvalue decomposition only makes sense for symmetric tensors, hence the need to only consider the symmetric part of the tensor, which is 1/2*(T+T.transposed()).

Parameters

• source (str) – preset type of source shape [‘ellipsoid’, ‘cylinder’, ‘cube’ or any specified Mesh]

• useEigenValues (bool) – color source glyph using the eigenvalues or by scalars.

• threeAxes (bool) –

  if False scale the source in the x-direction, the medium in the y-direction, and the minor in the z-direction. Then, the source is rotated so that the glyph’s local x-axis lies along the major eigenvector, y-axis along the medium eigenvector, and z-axis along the minor.

  If True three sources are produced, each of them oriented along an eigenvector and scaled according to the corresponding eigenvector.

• isSymmetric (bool) – If True each source glyph is mirrored (2 or 6 glyphs will be produced). The x-axis of the source glyph will correspond to the eigenvector on output.

• length (float) – distance from the origin to the tip of the source glyph along the x-axis

• scale (float) – scaling factor of the source glyph.

• maxScale (float) – clamp scaling at this factor.
