Extrema_ExtElC (const gp_Lin &C1, const gp_Lin &C2, const Standard_Real AngTol) | |
Calculates the distance between two lines. AngTol is used to test if the lines are parallel: Angle(C1,C2) < AngTol. | |
Extrema_ExtElC (const gp_Lin &C1, const gp_Circ &C2, const Standard_Real Tol) | |
Calculates the distance between a line and a circle. | |
Extrema_ExtElC (const gp_Lin &C1, const gp_Elips &C2) | |
Calculates the distance between a line and an ellipse. | |
Extrema_ExtElC (const gp_Lin &C1, const gp_Hypr &C2) | |
Calculates the distance between a line and a hyperbola. | |
Extrema_ExtElC (const gp_Lin &C1, const gp_Parab &C2) | |
Calculates the distance between a line and a parabola. | |
Extrema_ExtElC (const gp_Circ &C1, const gp_Circ &C2) | |
Calculates the distance between two circles. The circles can be parallel or identical. | |
Standard_Boolean | IsDone () const |
Returns True if the distances are found. | |
Standard_Boolean | IsParallel () const |
Returns True if the two curves are parallel. | |
Standard_Integer | NbExt () const |
Returns the number of extremum distances. | |
