Standard_Integer | NbPoints () const |
Returns the number of computed orthogonal projection points. Note: if this algorithm fails, NbPoints returns 0. | |
operator Standard_Integer () const | |
gp_Pnt | Point (const Standard_Integer Index) const |
Returns the orthogonal projection on the curve. Index is a number of a computed point. Exceptions Standard_OutOfRange if Index is not in the range [ 1,NbPoints ], where NbPoints is the number of solution points. | |
Quantity_Parameter | Parameter (const Standard_Integer Index) const |
Returns the parameter on the curve of the point, which is the orthogonal projection. Index is a number of a computed point. Exceptions Standard_OutOfRange if Index is not in the range [ 1,NbPoints ], where NbPoints is the number of solution points. | |
void | Parameter (const Standard_Integer Index, Quantity_Parameter &U) const |
Returns the parameter on the curve of the point, which is the orthogonal projection. Index is a number of a computed point. Exceptions Standard_OutOfRange if Index is not in the range [ 1,NbPoints ], where NbPoints is the number of solution points.- | |
Quantity_Length | Distance (const Standard_Integer Index) const |
Computes the distance between the point and its orthogonal projection on the curve. Index is a number of a computed point. Exceptions Standard_OutOfRange if Index is not in the range [ 1,NbPoints ], where NbPoints is the number of solution points. | |
gp_Pnt | NearestPoint () const |
Returns the nearest orthogonal projection of the point on the curve. Exceptions: StdFail_NotDone if this algorithm fails. | |
