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.

Set the cell id cached by the last evaluation.

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.

void vtkAMRInterpolatedVelocityField::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
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.

static bool vtkAMRInterpolatedVelocityField::FindGrid ( double  q[3],
vtkOverlappingAMR amrds,
unsigned int level,
unsigned int gridId 
)
static
int vtkAMRInterpolatedVelocityField::FunctionValues ( vtkDataSet ds,
double x,
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() in vtkInterpolatedVelocityField for cell location. In vtkCellLocatorInterpolatedVelocityField, this function is invoked just to handle vtkImageData and vtkRectilinearGrid that are not assigned with any vtkAbstractCellLocatot-type cell locator. If activated, returned vector will be tangential to the first three point of the cell
