Detailed Description

Efficient batch evaluator for cylinder grid points.

Uses analytical formula: P(u,v) = Location + R * (cos(u) * XDir + sin(u) * YDir) + v * ZDir

Where U is angle (0 to 2*PI) and V is height.

Usage:

GeomGridEval_Cylinder anEvaluator(myGeomCylinder);
NCollection_Array2<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myUParams, myVParams);

EvaluateGrid()

NCollection_Array2< gp_Pnt > GeomGridEval_Cylinder::EvaluateGrid	(	const NCollection_Array1< double > &	theUParams,
		const NCollection_Array1< double > &	theVParams ) const

Evaluate grid points at Cartesian product of U and V parameters.

Parameters

theUParams	array of U parameter values (angle)
theVParams	array of V parameter values (height)

Returns

2D array of evaluated points (1-based indexing)

EvaluateGridD1()

NCollection_Array2< GeomGridEval::SurfD1 > GeomGridEval_Cylinder::EvaluateGridD1	(	const NCollection_Array1< double > &	theUParams,
		const NCollection_Array1< double > &	theVParams ) const

Evaluate grid points with first partial derivatives.

Parameters

theUParams	array of U parameter values (angle)
theVParams	array of V parameter values (height)

Returns

2D array of SurfD1 (1-based indexing)

EvaluateGridD2()

NCollection_Array2< GeomGridEval::SurfD2 > GeomGridEval_Cylinder::EvaluateGridD2	(	const NCollection_Array1< double > &	theUParams,
		const NCollection_Array1< double > &	theVParams ) const

Evaluate grid points with first and second partial derivatives.

Parameters

theUParams	array of U parameter values (angle)
theVParams	array of V parameter values (height)

Returns

2D array of SurfD2 (1-based indexing)

EvaluateGridD3()

NCollection_Array2< GeomGridEval::SurfD3 > GeomGridEval_Cylinder::EvaluateGridD3	(	const NCollection_Array1< double > &	theUParams,
		const NCollection_Array1< double > &	theVParams ) const

Evaluate grid points with derivatives up to third order.

Parameters

theUParams	array of U parameter values (angle)
theVParams	array of V parameter values (height)

Returns

2D array of SurfD3 (1-based indexing)

EvaluateGridDN()

NCollection_Array2< gp_Vec > GeomGridEval_Cylinder::EvaluateGridDN	(	const NCollection_Array1< double > &	theUParams,
		const NCollection_Array1< double > &	theVParams,
		int	theNU,
		int	theNV ) const

Evaluate partial derivative d^(NU+NV)S/(dU^NU dV^NV) at all grid points. For a cylinder:

• U derivatives are cyclic (period 4): D_nU = R * (cyclic trig)
• V derivatives: D1V = ZDir, higher = 0
• Mixed: D_{nu,nv} = 0 for nv > 1

  Parameters

  theUParams	array of U parameter values (angle)
  theVParams	array of V parameter values (height)
  theNU	derivative order in U direction
  theNV	derivative order in V direction

  Returns

  2D array of derivative vectors (1-based indexing)

Geometry()

const occ::handle< Geom_CylindricalSurface > & GeomGridEval_Cylinder::Geometry ( ) const

inline

Returns the geometry handle.
