IntPatch_ALine (const IntAna_Curve &C, const Standard_Boolean Tang, const IntSurf_TypeTrans Trans1, const IntSurf_TypeTrans Trans2) | |
Creates an analytic intersection line when the transitions are In or Out. | |
IntPatch_ALine (const IntAna_Curve &C, const Standard_Boolean Tang, const IntSurf_Situation Situ1, const IntSurf_Situation Situ2) | |
Creates an analytic intersection line when the transitions are Touch. | |
IntPatch_ALine (const IntAna_Curve &C, const Standard_Boolean Tang) | |
Creates an analytic intersection line when the transitions are Undecided. | |
void | AddVertex (const IntPatch_Point &Pnt) |
To add a vertex in the list. | |
void | Replace (const Standard_Integer Index, const IntPatch_Point &Pnt) |
Replaces the element of range Index in the list of points. | |
void | SetFirstPoint (const Standard_Integer IndFirst) |
void | SetLastPoint (const Standard_Integer IndLast) |
Standard_Real | FirstParameter (Standard_Boolean &IsIncluded) const |
Returns the first parameter on the intersection line. If IsIncluded returns True, Value and D1 methods can be call with a parameter equal to FirstParamater. Otherwise, the parameter must be greater than FirstParameter. | |
Standard_Real | LastParameter (Standard_Boolean &IsIncluded) const |
Returns the last parameter on the intersection line. If IsIncluded returns True, Value and D1 methods can be call with a parameter equal to LastParamater. Otherwise, the parameter must be less than LastParameter. | |
gp_Pnt | Value (const Standard_Real U) |
Returns the point of parameter U on the analytic intersection line. | |
Standard_Boolean | D1 (const Standard_Real U, gp_Pnt &P, gp_Vec &Du) |
Returns Standard_True when the derivative at parameter U is defined on the analytic intersection line. In that case, Du is the derivative. Returns Standard_False when it is not possible to evaluate the derivative. In both cases, P is the point at parameter U on the intersection. | |
Standard_Boolean | FindParameter (const gp_Pnt &P, Standard_Real &Para) const |
Tries to find the parameter of the point P on the curve. If the method returns False, the "projection" is impossible, and the value of Para is not significant. If the method returns True, Para is the parameter of the nearest intersection between the curve and the iso-theta containing P. | |
Standard_Boolean | HasFirstPoint () const |
Returns True if the line has a known First point. This point is given by the method FirstPoint(). | |
Standard_Boolean | HasLastPoint () const |
Returns True if the line has a known Last point. This point is given by the method LastPoint(). | |
const IntPatch_Point & | FirstPoint () const |
Returns the IntPoint corresponding to the FirstPoint. An exception is raised when HasFirstPoint returns False. | |
const IntPatch_Point & | LastPoint () const |
Returns the IntPoint corresponding to the LastPoint. An exception is raised when HasLastPoint returns False. | |
Standard_Integer | NbVertex () const |
const IntPatch_Point & | Vertex (const Standard_Integer Index) const |
Returns the vertex of range Index on the line. | |
void | ComputeVertexParameters (const Standard_Real Tol) |
Set the parameters of all the vertex on the line. if a vertex is already in the line, its parameter is modified else a new point in the line is inserted. | |
