[vtkusers] vtkTensorGlyph input

[YaoHaofeng]

Hi, I have an array storing all the tensor values at each point in the image that I want to visualize, and i do:    vtkFloatArray *arr = vtkFloatArray::New();    arr->SetNumberOfTuples(dimension);    arr->SetNumberOfComponents(9);    //feed the tensor data into arr        vtkStructuredPoints *sp = vtkStructuredPoints::New();    sp->GetPointData()->SetTensors(arr);    sp->SetNumberOfScalarComponents(9);then feed the sp into vtkTensorGlyph, but it does not give me what i want, is it the correct way to do it? or i should feed the eigenvalues and eigenvectors into the structuredPoints?thankshank
