Describes functions to construct pipes. A pipe is built by
sweeping a curve (the section) along another curve (the path).
The Pipe class provides the following types of construction:

GeomFill_Pipe () | |
Constructs an empty algorithm for building pipes. Use the function Init to initialize it. | |

GeomFill_Pipe (const Handle< Geom_Curve > &Path, const Handle< Adaptor3d_HCurve > &Guide, const Handle< Geom_Curve > &FirstSect, const Standard_Boolean ByACR, const Standard_Boolean rotat) | |
Create a pipe with a constant section and with 1 guide-line. Use the function Perform to build the surface. All standard specific cases are detected in order to construct, according to the respective geometric nature of Path and the sections, a planar, cylindrical, conical, spherical or toroidal surface, a surface of linear extrusion or a surface of revolution. In the general case, the result is a BSpline surface (NURBS) built by approximation of a series of sections where: | |

void | Init (const Handle< Geom_Curve > &Path, const TColGeom_SequenceOfCurve &NSections) |
void | Init (const Handle< Adaptor3d_HCurve > &Path, const Handle< Adaptor3d_HCurve > &Curve1, const Handle< Adaptor3d_HCurve > &Curve2, const Standard_Real Radius) |
Create a pipe with a constant radius with 2 guide-line. | |
void | Init (const Handle< Geom_Curve > &Path, const Handle< Adaptor3d_HCurve > &Guide, const Handle< Geom_Curve > &FirstSect, const Standard_Boolean ByACR, const Standard_Boolean rotat) |
Initializes this pipe algorithm to build the following surface: | |
void | Perform (const Standard_Boolean WithParameters=Standard_False, const Standard_Boolean myPolynomial=Standard_False) |
Builds the pipe defined at the time of initialization of this algorithm. A description of the resulting surface is given under Constructors. If WithParameters (defaulted to false) is set to true, the approximation algorithm (used only in the general case of construction of a BSpline surface) builds the surface with a u parameter corresponding to the one of the path. Exceptions Standard_ConstructionError if a surface cannot be constructed from the data. Warning: It is the old Perform method, the next methode is recommended. | |
void | Perform (const Standard_Real Tol, const Standard_Boolean Polynomial, const GeomAbs_Shape Conti=GeomAbs_C1, const Standard_Integer MaxDegree=11, const Standard_Integer NbMaxSegment=30) |
detects the particular cases. And compute the surface. if none particular case is detected we make an approximation with respect of the Tolerance <Tol>, the continuty <Conti>, the maximum degree <MaxDegree>, the maximum number of span <NbMaxSegment> and the spine parametrization. //! If we can't create a surface with the data | |
const Handle_Geom_Surface & | Surface () const |
Returns the surface built by this algorithm. Warning Do not use this function before the surface is built (in this case the function will return a null handle). | |
Standard_Boolean | ExchangeUV () const |
The u parametric direction of the surface constructed by this algorithm usually corresponds to the evolution along the path and the v parametric direction corresponds to the evolution along the section(s). However, this rule is not respected when constructing certain specific Geom surfaces (typically cylindrical surfaces, surfaces of revolution, etc.) for which the parameterization is inversed. The ExchangeUV function checks for this, and returns true in all these specific cases. Warning Do not use this function before the surface is built. | |
void | GenerateParticularCase (const Standard_Boolean B) |
Sets a flag to try to create as many planes, cylinder,... as possible. Default value is <Standard_False>. | |
Standard_Boolean | GenerateParticularCase () const |
Returns the flag. | |
Standard_Real | ErrorOnSurf () const |
Returns the approximation's error. if the Surface is plane, cylinder ... this error can be 0. |
