Detailed Description

Efficient batch evaluator for 2D line grid points.

Uses direct analytical formula: P(t) = Location + t * Direction

Usage:

Geom2dGridEval_Line anEvaluator(myGeom2dLine);
NCollection_Array1<gp_Pnt2d> aGrid = anEvaluator.EvaluateGrid(myParams);

Member Function Documentation

EvaluateGrid()

NCollection_Array1< gp_Pnt2d > Geom2dGridEval_Line::EvaluateGrid ( const NCollection_Array1< double > & theParams ) const

inline

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< Geom2dGridEval::CurveD1 > Geom2dGridEval_Line::EvaluateGridD1 ( const NCollection_Array1< double > & theParams ) const

inline

Evaluate all grid points with first derivative. For a line, D1 is constant (the direction vector).

Parameters

theParams

array of parameter values

Returns

array of CurveD1 (1-based indexing), or empty array if geometry is null or no parameters

EvaluateGridD2()

NCollection_Array1< Geom2dGridEval::CurveD2 > Geom2dGridEval_Line::EvaluateGridD2 ( const NCollection_Array1< double > & theParams ) const

inline

Evaluate all grid points with first and second derivatives. For a line, D1 is constant and D2 is zero.

Parameters

theParams

array of parameter values

Returns

array of CurveD2 (1-based indexing), or empty array if geometry is null or no parameters

EvaluateGridD3()

NCollection_Array1< Geom2dGridEval::CurveD3 > Geom2dGridEval_Line::EvaluateGridD3 ( const NCollection_Array1< double > & theParams ) const

inline

Evaluate all grid points with first, second, and third derivatives. For a line, D1 is constant, D2 and D3 are zero.

Parameters

theParams

array of parameter values

Returns

array of CurveD3 (1-based indexing), or empty array if geometry is null or no parameters

EvaluateGridDN()

NCollection_Array1< gp_Vec2d > Geom2dGridEval_Line::EvaluateGridDN ( const NCollection_Array1< double > & theParams, int theN ) const

inline

Evaluate Nth derivative at all grid points. For a line: D1 = Direction, DN = 0 for N > 1.

Parameters

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

Returns

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

Geometry()

const occ::handle< Geom2d_Line > & Geom2dGridEval_Line::Geometry ( ) const

inline

Returns the geometry handle.
