Description of whiskers by quadratic 3D Bezier curves.
Left: schematic of a 3D Bezier curve representing a whisker (blue line), defined by its three control points cp0,cp1 and cp2 (blue dots). Middle, right: projection of the 3D Bezier curve, and its control points, onto horizontal and vertical image planes.
