Detailed Description

Efficient batch evaluator for Bezier curve grid points.

Uses BSplCLib to evaluate Bezier curves (treated as B-Splines).

Usage:

GeomGridEval_BezierCurve anEvaluator(myGeomBezier);
NCollection_Array1<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myParams);

Member Function Documentation

EvaluateGrid()

NCollection_Array1< gp_Pnt > GeomGridEval_BezierCurve::EvaluateGrid

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points.

Parameters

theParams

array of parameter values

Returns

array of evaluated points (1-based indexing), or empty array if geometry is null or no parameters

EvaluateGridD1()

NCollection_Array1< GeomGridEval::CurveD1 > GeomGridEval_BezierCurve::EvaluateGridD1

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first derivative.

Parameters

theParams

array of parameter values

Returns

array of CurveD1 (1-based indexing)

EvaluateGridD2()

NCollection_Array1< GeomGridEval::CurveD2 > GeomGridEval_BezierCurve::EvaluateGridD2

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first and second derivatives.

Parameters

theParams

array of parameter values

Returns

array of CurveD2 (1-based indexing)

EvaluateGridD3()

NCollection_Array1< GeomGridEval::CurveD3 > GeomGridEval_BezierCurve::EvaluateGridD3

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first, second, and third derivatives.

Parameters

theParams

array of parameter values

Returns

array of CurveD3 (1-based indexing)

EvaluateGridDN()

NCollection_Array1< gp_Vec > GeomGridEval_BezierCurve::EvaluateGridDN	(	const NCollection_Array1< double > &	theParams,
		int	theN ) const

Evaluate Nth derivative at all grid points. For orders 1-3, reuses EvaluateGridD1/D2/D3. For orders > 3, uses BSplCLib::DN.

Parameters

theParams	array of parameter values
theN	derivative order (N >= 1)

Returns

array of derivative vectors (1-based indexing)

Geometry()

const occ::handle< Geom_BezierCurve > & GeomGridEval_BezierCurve::Geometry ( ) const

inline

Returns the geometry handle.
