# StdPrs_Curve Class Reference

A framework to define display of lines, arcs of circles
and conic sections.
This is done with a fixed number of points, which can be modified.

static Standard_EXPORT void | Add (const Handle(Prs3d_Presentation)&aPresentation, const Adaptor3d_Curve &aCurve, const Handle(Prs3d_Drawer)&aDrawer, const Standard_Boolean drawCurve=Standard_True)
| Adds to the presentation aPresentation the drawing of the curve aCurve. The aspect is defined by LineAspect in aDrawer. If drawCurve equals Standard_False the curve will not be displayed, it is used if the curve is a part of some shape and PrimitiveArray visualization approach is activated (it is activated by default). .
static Standard_EXPORT void | Add (const Handle(Prs3d_Presentation)&aPresentation, const Adaptor3d_Curve &aCurve, const Standard_Real U1, const Standard_Real U2, const Handle(Prs3d_Drawer)&aDrawer, const Standard_Boolean drawCurve=Standard_True)
| Adds to the presentation aPresentation the drawing of the curve aCurve. The aspect is defined by LineAspect in aDrawer. The drawing will be limited between the points of parameter U1 and U2. If drawCurve equals Standard_False the curve will not be displayed, it is used if the curve is a part of some shape and PrimitiveArray visualization approach is activated (it is activated by default). .
static Standard_EXPORT void | Add (const Handle(Prs3d_Presentation)&aPresentation, const Adaptor3d_Curve &aCurve, const Quantity_Length aDeflection, const Handle(Prs3d_Drawer)&aDrawer, TColgp_SequenceOfPnt &Points, const Standard_Boolean drawCurve=Standard_True)
| adds to the presentation aPresentation the drawing of the curve aCurve. The aspect is the current aspect. aDeflection is used in the circle case. Points give a sequence of curve points. If drawCurve equals Standard_False the curve will not be displayed, it is used if the curve is a part of some shape and PrimitiveArray visualization approach is activated (it is activated by default).
static Standard_EXPORT void | Add (const Handle(Prs3d_Presentation)&aPresentation, const Adaptor3d_Curve &aCurve, const Standard_Real U1, const Standard_Real U2, const Quantity_Length aDeflection, TColgp_SequenceOfPnt &Points, const Standard_Integer aNbPoints=30, const Standard_Boolean drawCurve=Standard_True)

adds to the presentation aPresentation the drawing of the curve
aCurve.
The aspect is the current aspect.
The drawing will be limited between the points of parameter
U1 and U2.
aDeflection is used in the circle case.
Points give a sequence of curve points.
If drawCurve equals Standard_False the curve will not be displayed,
it is used if the curve is a part of some shape and PrimitiveArray
visualization approach is activated (it is activated by default).

static Standard_EXPORT Standard_Boolean | Match (const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Z, const Quantity_Length aDistance, const Adaptor3d_Curve &aCurve, const Handle(Prs3d_Drawer)&aDrawer)
| returns true if the distance between the point (X,Y,Z) and the drawing of the curve is less than aDistance.
static Standard_EXPORT Standard_Boolean | Match (const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Z, const Quantity_Length aDistance, const Adaptor3d_Curve &aCurve, const Quantity_Length aDeflection, const Standard_Real aLimit, const Standard_Integer aNbPoints)
| returns true if the distance between the point (X,Y,Z) and the drawing of the curve is less than aDistance.
