Users can control the visual quality of the skeleton, choosing between highly optimized geometry (A and C) for global far views or high-quality reconstructions (B and D) for close up views. Morphology polylines are rendered using bevel objects with 4 and 16 sides in A and B, respectively. The piecewise segments of the polylines (C) might limit the visual quality in case of close ups; therefore, we added another parameter to use spline interpolation to smooth their curvature (D)
