Siluroid (n=1)
A siluroid is a curve made of three lobes: the main one extends along the x axis while the two secondaries lie respectively in the second and in the third quadrant of the Cartesian plane.
Generatrix circle
The curve can be generated from a normalized circle by using a building process described in Generation section.
Arc names
Sometimes it is useful to name specific arcs and major points of the curve.
