Detailed Description

An abstract class for obtaining the interpolated velocity values at a point.

vtkCompositeInterpolatedVelocityField acts as a continuous velocity field by performing cell interpolation on one or more underlying vtkDataSets.

Warning: vtkCompositeInterpolatedVelocityField is not thread safe. A new instance should be created by each thread.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

◆ PrintSelf()

void vtkCompositeInterpolatedVelocityField::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkAbstractInterpolatedVelocityField.

Reimplemented in vtkInterpolatedVelocityField.

◆ AddDataSet()

virtual void vtkCompositeInterpolatedVelocityField::AddDataSet ( vtkDataSet * dataset )

pure virtual

Add a dataset for implicit velocity function evaluation.

If more than one dataset is added, the evaluation point is searched in all until a match is found. THIS FUNCTION DOES NOT CHANGE THE REFERENCE COUNT OF dataset FOR THREAD SAFETY REASONS.

Implemented in vtkCellLocatorInterpolatedVelocityField, and vtkInterpolatedVelocityField.

◆ GetLastDataSetIndex()

virtual int vtkCompositeInterpolatedVelocityField::GetLastDataSetIndex ( )

virtual

Get the most recently visited dataset and its id.

The dataset is used for a guess regarding where the next point will be, without searching through all datasets. When setting the last dataset, care is needed as no reference counting or checks are performed. This feature is intended for custom interpolators only that cache datasets independently.
