Describes functions for building bisecting lines between two 2D lines.
A bisecting line between two lines is such that each of its
points is at the same distance from the two lines.
If the two lines are secant, there are two orthogonal
bisecting lines which share the angles made by the two
straight lines in two equal parts. If D1 and D2 are the
unit vectors of the two straight lines, those of the two
bisecting lines are collinear with the following vectors:

GccAna_Lin2dBisec (const gp_Lin2d &Lin1, const gp_Lin2d &Lin2) | |
Constructs bisecting lines between the two lines Lin1 and Lin2. | |
Standard_Boolean | IsDone () const |
Returns True when the algorithm succeded. | |
Standard_Integer | NbSolutions () const |
Returns the number of solutions and raise NotDone if the constructor wasn't called before. | |
gp_Lin2d | ThisSolution (const Standard_Integer Index) const |
Returns the solution number Index . The first solution is the inside one and the second is the outside one. For the first solution the direction is D1+D2 (D1 is the direction of the first argument and D2 the direction of the second argument). For the second solution the direction is D1-D2. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. | |
void | Intersection1 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns informations about the intersection point between the result number Index and the first argument. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. | |
void | Intersection2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns informations about the intersection point between the result number Index and the second argument. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. |
