Public Member Functions  
GeomAPI_IntCS ()  
Creates an empty object. Use the function Perform for further initialization of the algorithm by the curve and the surface. More...  
GeomAPI_IntCS (const Handle< Geom_Curve > &C, const Handle< Geom_Surface > &S)  
Computes the intersections between the curve C and the surface S. Warning Use function IsDone to verify that the intersections are computed successfully. More...  
void  Perform (const Handle< Geom_Curve > &C, const Handle< Geom_Surface > &S) 
This function Initializes an algorithm with the curve C and the surface S and computes the intersections between C and S. Warning Use function IsDone to verify that the intersections are computed successfully. More...  
Standard_Boolean  IsDone () const 
Returns true if the intersections are successfully computed. More...  
Standard_Integer  NbPoints () const 
Returns the number of Intersection Points if IsDone returns True. else NotDone is raised. More...  
const gp_Pnt &  Point (const Standard_Integer Index) const 
Returns the Intersection Point of range <Index>in case of cross intersection. Raises NotDone if the computation has failed or if the computation has not been done raises OutOfRange if Index is not in the range <1..NbPoints> More...  
void  Parameters (const Standard_Integer Index, Standard_Real &U, Standard_Real &V, Standard_Real &W) const 
Returns parameter W on the curve and (parameters U,V) on the surface of the computed intersection point of index Index in case of cross intersection.

Returns the number of computed intersection segments in case of tangential intersection. Exceptions StdFail_NotDone if the intersection algorithm fails or is not initialized. More...  
Handle< Geom_Curve >  Segment (const Standard_Integer Index) const 
Returns the computed intersection segment of index Index in case of tangential intersection. Intersection segment is a portion of the initial curve tangent to surface. Exceptions StdFail_NotDone if intersection algorithm fails or is not initialized. Standard_OutOfRange if Index is not in the range [ 1,NbSegments ], where NbSegments is the number of computed intersection segments. More...  
void  Parameters (const Standard_Integer Index, Standard_Real &U1, Standard_Real &V1, Standard_Real &U2, Standard_Real &V2) const 
Returns the parameters of the first (U1,V1) and the last (U2,V2) points of curve's segment on the surface in case of tangential intersection. Index is the number of computed intersection segments. Exceptions StdFail_NotDone if intersection algorithm fails or is not initialized.
