Detailed Description

A framework to provide display of Bezier or BSpline curves.

Member Function Documentation

static void StdPrs_PoleCurve::Add ( const Handle< Prs3d_Presentation > &  aPresentation, const Adaptor3d_Curve &  aCurve, const Handle< Prs3d_Drawer > &  aDrawer  )

static

 Defines display of BSpline and Bezier curves. <br>

Adds the 3D curve aCurve to the
StdPrs_PoleCurve algorithm. This shape is found in
the presentation object aPresentation, and its display
attributes are set in the attribute manager aDrawer.
The curve object from Adaptor3d provides data from
a Geom curve. This makes it possible to use the
surface in a geometric algorithm.

static Standard_Boolean StdPrs_PoleCurve::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  )

static

returns true if the distance between the point (X,Y,Z) and the
broken line made of the poles is less then aDistance.

static Standard_Integer StdPrs_PoleCurve::Pick ( 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  )

static

returns the pole the most near of the point (X,Y,Z) and
returns its range. The distance between the pole and
(X,Y,Z) must be less then aDistance. If no pole corresponds, 0 is returned.
