◆ CopyParameters()

void vtkAMRInterpolatedVelocityField::CopyParameters ( vtkAbstractInterpolatedVelocityField * from )

overridevirtual

This generally is used to copy from instance prototype to another, or to copy interpolators between thread instances. Sub-classes can contribute to the parameter copying process via chaining.

Reimplemented from vtkAbstractInterpolatedVelocityField.

◆ SetLastCellId() [1/2]

void vtkAMRInterpolatedVelocityField::SetLastCellId ( vtkIdType c )

◆ FunctionValues() [1/6]

int vtkAMRInterpolatedVelocityField::FunctionValues	(	double *	x,
		double *	f
	)

overridevirtual

Evaluate the velocity field f at point p.

If it succeeds, then both the last data set (this->LastDataSet) and the last data set location (this->LastLevel, this->LastId) will be set according to where p is found. If it fails, either p is out of bound, in which case both the last data set and the last location will be invalid or, in a multi-process setting, p is inbound but not on the processor. In the last case, the last data set location is still valid

Implements vtkAbstractInterpolatedVelocityField.

◆ FunctionValues() [2/6]

int vtkAMRInterpolatedVelocityField::FunctionValues	(	vtkDataSet *	ds,

		double *	f
	)

inlineoverrideprotectedvirtual

Evaluate the velocity field f at point (x, y, z) in a specified dataset by invoking vtkDataSet::FindCell() to locate the next cell if the given point is outside the current cell.

To address vtkPointSet, vtkPointLocator is involved via vtkPointSet::FindCell() using CLOSEST_POINT strategy for cell location. In vtkCompositeInterpolatedVelocityField with a CELL_LOCATOR strategy, this function is invoked just to handle vtkImageData and vtkRectilinearGrid that are not assigned with any vtkAbstractCellLocator-type cell locator. If activated, returned vector will be tangential to the first three point of the cell

Definition at line 96 of file vtkAMRInterpolatedVelocityField.h.

◆ SelfInitialize()

int vtkAMRInterpolatedVelocityField::SelfInitialize ( )

overrideprotectedvirtual

Method to initialize the velocity field.

Generally this must be called when performing threaded operations; however if not called apriori it will be called in the first call to FunctionValues(), which implicitly assumes that this is being used in serial operation.

Reimplemented from vtkAbstractInterpolatedVelocityField.

◆ FunctionValues() [5/6]

virtual int vtkFunctionSet::FunctionValues	(	double *	x,
		double *	f
	)

inlinevirtual

Evaluate functions at x_j.

x and f have to point to valid double arrays of appropriate sizes obtained with GetNumberOfFunctions() and GetNumberOfIndependentVariables. If you inherit this class, make sure to reimplement at least one of the two FunctionValues signatures.
