Abstract interface for sets of functions.
defines cell interface
iterator used to traverse cells
defines dataset interface
Interface for obtaining interpolated velocity values.
virtual void AddDataSet(vtkGenericDataSet *dataset)
Add a dataset used for the implicit function evaluation.
int FunctionValues(double *x, double *f) override
Evaluate the velocity field, f, at (x, y, z, t).
void ClearLastCell()
Set the last cell id to -1 so that the next search does not start from the previous cell.
static vtkGenericInterpolatedVelocityField * New()
Construct a vtkGenericInterpolatedVelocityField with no initial data set.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkGenericAdaptorCell * GetLastCell()
Return the cell cached from last evaluation.
virtual void CopyParameters(vtkGenericInterpolatedVelocityField *from)
Copy the user set parameters from source.
int GetLastLocalCoordinates(double pcoords[3])
Returns the interpolation weights cached from last evaluation if the cached cell is valid (returns 1)...
a simple class to control print indentation
Definition: vtkIndent.h:40
vtkSetMacro(IgnoreDriverBugs, bool)
Updates the extensions string.
vtkBooleanMacro(IgnoreDriverBugs, bool)
Updates the extensions string.
vtkGetStringMacro(ExtensionsString)
Returns a string listing all available extensions.
