Public Member Functions | |
Standard_EXPORT | Geom_Line (const gp_Ax1 &A1) |
Creates a line located in 3D space with the axis placement A1. The Location of A1 is the origin of the line. . | |
Standard_EXPORT | Geom_Line (const gp_Lin &L) |
Creates a line from a non transient line from package gp. . | |
Standard_EXPORT | Geom_Line (const gp_Pnt &P, const gp_Dir &V) |
Constructs a line passing through point P and parallel to vector V (P and V are, respectively, the origin and the unit vector of the positioning axis of the line). . | |
Standard_EXPORT void | SetLin (const gp_Lin &L) |
Set <me> so that <me> has the same geometric properties as L. . | |
Standard_EXPORT void | SetDirection (const gp_Dir &V) |
changes the direction of the line. | |
Standard_EXPORT void | SetLocation (const gp_Pnt &P) |
changes the "Location" point (origin) of the line. | |
Standard_EXPORT void | SetPosition (const gp_Ax1 &A1) |
changes the "Location" and a the "Direction" of <me>. | |
Standard_EXPORT gp_Lin | Lin () const |
Returns non transient line from gp with the same geometric properties as <me> . | |
Standard_EXPORT const gp_Ax1 & | Position () const |
Returns the positioning axis of this line; this is also its local coordinate system. . | |
Standard_EXPORT void | Reverse () |
Changes the orientation of this line. As a result, the unit vector of the positioning axis of this line is reversed. . | |
Standard_EXPORT Standard_Real | ReversedParameter (const Standard_Real U) const |
Computes the parameter on the reversed line for the point of parameter U on this line. For a line, the returned value is -U. . | |
Standard_EXPORT Standard_Real | FirstParameter () const |
Returns the value of the first parameter of this line. This is Standard_Real::RealFirst(). . | |
Standard_EXPORT Standard_Real | LastParameter () const |
Returns the value of the last parameter of this line. This is Standard_Real::RealLast(). . | |
Standard_EXPORT Standard_Boolean | IsClosed () const |
returns False | |
Standard_EXPORT Standard_Boolean | IsPeriodic () const |
returns False | |
Standard_EXPORT GeomAbs_Shape | Continuity () const |
Returns GeomAbs_CN, which is the global continuity of any line. . | |
Standard_EXPORT Standard_Boolean | IsCN (const Standard_Integer N) const |
returns True. //! Raised if N < 0. | |
Standard_EXPORT void | D0 (const Standard_Real U, gp_Pnt &P) const |
Returns in P the point of parameter U. P (U) = O + U * Dir where O is the "Location" point of the line and Dir the direction of the line. . | |
Standard_EXPORT void | D1 (const Standard_Real U, gp_Pnt &P, gp_Vec &V1) const |
Returns the point P of parameter u and the first derivative V1. . | |
Standard_EXPORT void | D2 (const Standard_Real U, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2) const |
Returns the point P of parameter U, the first and second derivatives V1 and V2. V2 is a vector with null magnitude for a line. . | |
Standard_EXPORT void | D3 (const Standard_Real U, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2, gp_Vec &V3) const |
V2 and V3 are vectors with null magnitude for a line. . | |
Standard_EXPORT gp_Vec | DN (const Standard_Real U, const Standard_Integer N) const |
The returned vector gives the value of the derivative for the order of derivation N. //! Raised if N < 1. . | |
Standard_EXPORT void | Transform (const gp_Trsf &T) |
Applies the transformation T to this line. . | |
virtual Standard_EXPORT Standard_Real | TransformedParameter (const Standard_Real U, const gp_Trsf &T) const |
Returns the parameter on the transformed curve for the transform of the point of parameter U on <me>. me->Transformed(T)->Value(me->TransformedParameter(U,T)) is the same point as me->Value(U).Transformed(T) This methods returns <u> * T.ScaleFactor() . | |
virtual Standard_EXPORT Standard_Real | ParametricTransformation (const gp_Trsf &T) const |
Returns a coefficient to compute the parameter on the transformed curve for the transform of the point on <me>. Transformed(T)->Value(U * ParametricTransformation(T)) is the same point as Value(U).Transformed(T) This methods returns T.ScaleFactor() . | |
Standard_EXPORT Handle_Geom_Geometry | Copy () const |
Creates a new object which is a copy of this line. . | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
