IGESConvGeom_GeomBuilder Class Reference

This class provides some useful basic tools to build IGESGeom
curves, especially :
define a curve in a plane in 3D space (ex. Circular or Conic
arc, or Copious Data defined in 2D)
make a CopiousData from a list of points/vectors
.

Standard_EXPORT IGESConvGeom_GeomBuilder ()
 Creates a GeomBuilder at initial state.
.
Standard_EXPORT void Clear ()
 Clears list of Points/Vectors and data about Transformation
.
Standard_EXPORT void AddXY (const gp_XY &val)
 Adds a XY (Z=0) to the list of points
.
Standard_EXPORT void AddXYZ (const gp_XYZ &val)
 Adds a XYZ to the list of points
.
Standard_EXPORT void AddVec (const gp_XYZ &val)
 Adds a Vector part to the list of points. It will be used
for CopiousData, datatype=3, only.
AddXY and AddXYZ consider a null vector part (0,0,0)
AddVec adds to the last added XY or XYZ
.
Standard_EXPORT Standard_Integer NbPoints () const
 Returns the count of already recorded points
.
Standard_EXPORT gp_XYZ Point (const Standard_Integer num) const
 Returns a point given its rank (if added as XY, Z will be 0)
.
Standard_EXPORT Handle_IGESGeom_CopiousData MakeCopiousData (const Standard_Integer datatype, const Standard_Boolean polyline=Standard_False) const
 Makes a CopiousData with the list of recorded Points/Vectors
according to <datatype>, which must be 1,2 or 3
If <polyline> is given True, the CopiousData is coded as a
Polyline, but <datatype> must not be 3
<datatype> = 1 : Common Z is computed as average of all Z
<datatype> = 1 or 2 : Vectors are ignored
.
Standard_EXPORT Handle_TColgp_HArray1OfXY MakeXY () const
 Returns the list of points as a HArray1OfXY. Z are ignored.
.
Standard_EXPORT Handle_TColgp_HArray1OfXYZ MakeXYZ () const
 Returns the list of points as a HArray1OfXYZ
.
Standard_EXPORT gp_Trsf Position () const
 Returns the Position in which the method EvalXYZ will
evaluate a XYZ. It can be regarded as defining a local system.
It is initially set to Identity
.
Standard_EXPORT void SetPosition (const gp_Trsf &pos)
 Sets final position from an already defined Trsf
.
Standard_EXPORT void SetPosition (const gp_Ax3 &pos)
 Sets final position from an Ax3
.
Standard_EXPORT void SetPosition (const gp_Ax2 &pos)
 Sets final position from an Ax2
.
Standard_EXPORT void SetPosition (const gp_Ax1 &pos)
 Sets final position from an Ax1
(this means that origin point and Z-axis are defined, the
other axes are defined arbitrarily)
.
Standard_EXPORT Standard_Boolean IsIdentity () const
 Returns True if the Position is Identity
.
Standard_EXPORT Standard_Boolean IsTranslation () const
 Returns True if the Position is a Translation only
Remark : Identity and ZOnly will answer True
.
Standard_EXPORT Standard_Boolean IsZOnly () const
 Returns True if the Position corresponds to a Z-Displacement,
i.e. is a Translation only, and only on Z
Remark : Identity will answer True
.
Standard_EXPORT void EvalXYZ (const gp_XYZ &val, Standard_Real &X, Standard_Real &Y, Standard_Real &Z) const
 Evaluates a XYZ value in the Position already defined.
Returns the transformed coordinates.
For a 2D definition, X,Y will then be used to define a XY and
Z will be regarded as a Z Displacement (can be ignored)
.
Standard_EXPORT Handle_IGESGeom_TransformationMatrix MakeTransformation (const Standard_Real unit=1) const
 Returns the IGES Transformation which corresponds to the
Position. Even if it is an Identity : IsIdentity should be
tested first.
<unit> is the unit value in which the model is created :
it is used to convert translation part
.
