Let us consider the intersection of y with x:
Let us eliminate three of the four parameters; for instance resolving for k, there can be obtained:
and the equation of the intersecting curve in the reference (O,ij, i2, i3):
If the reference system is changed (C, ij, i2, i3) and rotated in (C, s, v, i3):
