Fig. 1: Rendered and clipped view of the reconstructed results of the scattering tensor tomography.

Only half of the cylindrical sample is shown to better visualise the inner structures surrounding the core. For a better visual interpretation, streamlines calculated based on the Runge-Kutta method are used (tool provided by the Paraview Guide⁵⁰). Note, that those streamlines do not represent single fibres but a dominant material orientation. The three-dimensional fibre orientations p_i in (a) are colour-coded according to the colour sphere, which maps the absolute values of the orientation vector coordinates ∣x, y, z∣ to the RGB colour components. The colours in (b) and (c) represent the Mean Scattering MS ∈ [0, 1] and the Fractional Anisotropy FA ∈ [0, 1] signals, respectively.
