Detailed Description

scale and orient glyph(s) according to eigenvalues and eigenvectors of symmetrical part of tensor

vtkTensorGlyph is a filter that copies a geometric representation (specified as polygonal data) to every input point. The geometric representation, or glyph, can be scaled and/or rotated according to the tensor at the 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()).

If the boolean variable ThreeGlyphs is not set the major eigenvalue scales the glyph in the x-direction, the medium in the y-direction, and the minor in the z-direction. Then, the glyph 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 the boolean variable ThreeGlyphs is set three glyphs are produced, each of them oriented along an eigenvector and scaled according to the corresponding eigenvector.

If the boolean variable Symmetric is set each glyph is mirrored (2 or 6 glyphs will be produced)

The x-axis of the source glyph will correspond to the eigenvector on output. Point (0,0,0) in the source will be placed in the data point. Variable Length will normally correspond to the distance from the origin to the tip of the source glyph along the x-axis, but can be changed to produce other results when Symmetric is on, e.g. glyphs that do not touch or that overlap.

Please note that when Symmetric is false it will generally be better to place the source glyph from (-0.5,0,0) to (0.5,0,0), i.e. centred at the origin. When symmetric is true the placement from (0,0,0) to (1,0,0) will generally be more convenient.

A scale factor is provided to control the amount of scaling. Also, you can turn off scaling completely if desired. The boolean variable ClampScaling controls the maximum scaling (in conjunction with MaxScaleFactor.) This is useful in certain applications where singularities or large order of magnitude differences exist in the eigenvalues.

If the boolean variable ColorGlyphs is set to true the glyphs are colored. The glyphs can be colored using the input scalars (SetColorModeToScalars), which is the default, or colored using the eigenvalues (SetColorModeToEigenvalues).

Another instance variable, ExtractEigenvalues, has been provided to control extraction of eigenvalues/eigenvectors. If this boolean is false, then eigenvalues/eigenvectors are not extracted, and the columns of the tensor are taken as the eigenvectors (the norm of column, always positive, is the eigenvalue). This allows additional capability over the vtkGlyph3D object. That is, the glyph can be oriented in three directions instead of one.
