| Extrema_ExtPElC (const gp_Pnt &P, const gp_Circ &C, const Standard_Real Tol, const Standard_Real Uinf, const Standard_Real Usup) | |
| Calculates the 2 extremum distances between the point P and the segment [Uinf,Usup] of the circle C. Tol is used to determine if P is on the axis of the circle or if an extremum is on an endpoint of the segment. If P is on the axis of the circle, there are infinite solution then IsDone(me)=False. The conditions on the Uinf and Usup are: 0. <= Uinf <= 2.*PI and Usup > Uinf. If Usup > Uinf + 2.*PI, then only the solutions in the range [Uinf,Uinf+2.*PI[ are computed. More... | |

| Calculates the 4 extremum distances between the point P and the segment [Uinf,Usup] of the elipse C. Tol is used to determine if the point is on the axis of the elipse and if the major radius is equal to the minor radius or if an extremum is on an endpoint of the segment. If P is on the axis of the elipse, there are infinite solution then IsDone(me)=False. The conditions on the Uinf and Usup are: 0. <= Uinf <= 2.*PI and Usup > Uinf.
