SetTensorRotationMatrix()

virtual void vtkDiffusionTensorMathematics::SetTensorRotationMatrix ( vtkMatrix4x4 *  )

virtual

Description This matrix is only used for ColorByOrientation. We transform the tensor orientation by this matrix before setting the output RGB values. This is useful to put the output colors into a standard coordinate system (i.e. RAS) regardless of the data scan order. Example usage is as follows: 1) If tensors are to be displayed in a coordinate system that is not IJK (array-based), and the whole volume is being rotated, each tensor needs also to be rotated. First find the matrix that positions your volume. (This is how the entire volume is positioned, not the matrix that positions an arbitrary reformatted slice.) 2) Remove scaling and translation from this matrix; we just need to rotate each tensor. 3) Set TensorRotationMatrix to this rotation matrix.
