IGESConvGeom


IGESConvGeom Class Reference

This package is intended to gather geometric conversion which
are not immediate but can be used for several purposes :
mainly, standard conversion to and from CasCade geometric and
topologic data, and adaptations of IGES files as required
(as replacing Spline entities to BSpline equivalents).

static Standard_EXPORT Standard_Integer SplineCurveFromIGES (const Handle(IGESGeom_SplineCurve)&igesent, const Standard_Real epscoef, const Standard_Real epsgeom, Handle(Geom_BSplineCurve)&result)
 Converts a SplineCurve from IGES to a BSplineCurve from CasCade
<epscoef> gives tolerance to consider coefficient to be nul
<epsgeom> gives tolerance to consider poles to be equal
The returned value is a status with these possible values :
- 0 OK, done
- 1 the result is not guaranteed to be C0 (with <epsgeom>)
- 2 SplineType not processed (allowed : max 3)
(no result produced)
- 3 error during creation of control points
(no result produced)
- 4 polynomial equation is not correct (no result produced)
- 5 less than one segment (no result produced)
.
static Standard_EXPORT Standard_Integer IncreaseCurveContinuity (const Handle(Geom_BSplineCurve)&curve, const Standard_Real epsgeom, const Standard_Integer continuity=2)
 Tries to increase curve continuity with tolerance <epsgeom>
<continuity> is the new desired continuity, can be 1 or 2
(more than 2 is considered as 2).
Returns the new maximum continuity obtained on all knots.
Remark that, for instance with <continuity> = 2, even if not
all the knots can be passed to C2, all knots which can be are.
.
static Standard_EXPORT Standard_Integer IncreaseCurveContinuity (const Handle(Geom2d_BSplineCurve)&curve, const Standard_Real epsgeom, const Standard_Integer continuity=2)
static Standard_EXPORT Standard_Integer SplineSurfaceFromIGES (const Handle(IGESGeom_SplineSurface)&igesent, const Standard_Real epscoef, const Standard_Real epsgeom, Handle(Geom_BSplineSurface)&result)
 Converts a SplineSurface from IGES to a BSplineSurface from CasCade
<epscoef> gives tolerance to consider coefficient to be nul
<epsgeom> gives tolerance to consider poles to be equal
The returned value is a status with these possible values :
- 0 OK, done
- 1 the result is not guaranteed to be C0 (with <epsgeom>)
- 2 degree is not compatible with code boundary type
(warning) but C0 is OK
- 3 idem but C0 is not guaranteed (warning)
- 4 degree has been determined to be nul, either in U or V
(no result produced)
- 5 less than one segment in U or V (no result produced)
.
static Standard_EXPORT Standard_Integer IncreaseSurfaceContinuity (const Handle(Geom_BSplineSurface)&surface, const Standard_Real epsgeom, const Standard_Integer continuity=2)
 Tries to increase Surface continuity with tolerance <epsgeom>
<continuity> is the new desired continuity, can be 1 or 2
(more than 2 is considered as 2).
Returns the new maximum continuity obtained on all knots.
Remark that, for instance with <continuity> = 2, even if not
all the knots can be passed to C2, all knots which can be are.
