A concrete class for obtaining the interpolated velocity values at a point.
vtkInterpolatedVelocityField acts as a continuous velocity field via cell interpolation on a vtkDataSet, NumberOfIndependentVariables = 4 (x,y,z,t) and NumberOfFunctions = 3 (u,v,w). As a concrete sub-class of vtkCompositeInterpolatedVelocityField, this class adopts two levels of cell caching for faster though less robust cell location than its sibling class vtkCellLocatorInterpolatedVelocityField. Level #0 begins with intra-cell caching. Specifically, if the previous cell is valid and the next point is still within it, ( vtkCell::EvaluatePosition() returns 1, coupled with the new parametric coordinates and weights ), the function values are interpolated and vtkCell::EvaluatePosition() is invoked only. If it fails, level #1 follows by inter-cell location of the target cell (that contains the next point). By inter-cell, the previous cell gives an important clue / guess or serves as an immediate neighbor to aid in the location of the target cell (as is typically the case with integrating a streamline across cells) by means of vtkDataSet:: FindCell(). If this still fails, a global cell search is invoked via vtkDataSet::FindCell().
Regardless of inter-cell or global search, a point locator is employed as a crucial tool underlying the interpolation process. The use of a point locator, while faster than a cell locator, is not optimal and may cause vtkInterpolatedVelocityField to return incorrect results (i.e., premature streamline termination) for datasets defined on complex grids (especially those this discontinuous/incompatible cells). In these cases, try vtkCellLocatorInterpolatedVelocityField which produces the best results at the cost of speed.

- vtkInterpolatedVelocityField is not thread safe. A new instance should be created by each thread.
