| Defines display of BSpline and Bezier curves. 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.

Detailed Description
A framework to provide display of Bezier or BSpline curves (by drawing a broken line linking the poles of the curve).
Member Function Documentation
◆ Add()
|
static |
Defines display of BSpline and Bezier curves. 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.
◆ Match()
|
static |
returns true if the distance between the point (X,Y,Z) and the broken line made of the poles is less then aDistance.
◆ Pick()
|
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.
