Hey Pawel,
If you happen to be working from a binary version of ParaView, you
should also be able to try it out by loading the XML that Jean
provided with Tools->Manage Plugins/Extensions..., and then the issue
of vtkTensorGlyphs not naming the arrays can be temporarily solved by
adding a Python Programmable Filter after the Tensor Glyphs filter
with a script like:
pdi = self.GetInput()
pdata = pdi.GetPointData()
pdata.GetScalars().SetName('Scalars')
pdata.GetNormals().SetName('Normals')
pdata.GetTensors().SetName('Tensors')
pdo = self.GetOutput()
pdo.ShallowCopy(pdi)
I haven't tried any of this with vtkTensorGlyphs, but I used a similar
method yesterday to try vtkImplicitModeller and compensate for the
fact that this filter also does not name the output scalars.

What you describe seems to be exactly what the vtkTensorGlyph does.
See details here http://www.vtk.org/doc/nightly/html/classvtkTensorGlyph.html
Tensor Glyphing is not in ParaView yet. But a ctest exist (if Python
is enabled)
./VTK/Graphics/Testing/Python/TenEllip.py
You can add Tensor Glyph yourself with a pluggin. Here are the XML
necessary. The CMakelists.txt is this:
############
cmake_minimum_required(VERSION 2.6)
FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})
ADD_PARAVIEW_PLUGIN(ExtraSMPlugin "1.0"
SERVER_MANAGER_XML extras_Server.xml
)
ADD_PARAVIEW_PLUGIN(ExtraGUIPlugin "1.0"
GUI_RESOURCES extras.qrc )
#############
The file extras.qrc is this:
############
<RCC>
<qresource prefix="/ParaViewResources" >
<file>extras.xml</file>
</qresource>
</RCC>
############
There is a complication. The data fields created by vtkTensorGlyph
(and vtkPointLoad) are not named. ParaView will not color them. You
need to add two lines of code in vtkTensorGlyph.cxx and
vtkPointLoad.cxx immediately after the declaration of
newNormals = vtkFloatArray::New();
newScalars = vtkFloatArray::New();
newTensors = vtkFloatArray::New();
newScalars->SetName("Scalars");
newNormals->SetName("Normals");
newTensors->SetName("Tensors");
hope it fits the bill. Caveat Emptor.
