Interface for obtaining interpolated velocity values.
<p>
<a class="el" href="a00599.html" title="Interface for obtaining interpolated velocity values.">vtkGenericInterpolatedVelocityField</a> acts as a continuous velocity field by performing cell interpolation on the underlying <a class="el" href="a00374.html" title="abstract class to specify dataset behavior">vtkDataSet</a>. This is a concrete sub-class of <a class="el" href="a00570.html" title="Abstract interface for sets of functions.">vtkFunctionSet</a> with NumberOfIndependentVariables = 4 (x,y,z,t) and NumberOfFunctions = 3 (u,v,w). Normally, every time an evaluation is performed, the cell which contains the point (x,y,z) has to be found by calling FindCell. This is a computationally expansive operation. In certain cases, the cell search can be avoided or shortened by providing a guess for the cell iterator. For example, in streamline integration, the next evaluation is usually in the same or a neighbour cell. For this reason, <a class="el" href="a00599.html" title="Interface for obtaining interpolated velocity values.">vtkGenericInterpolatedVelocityField</a> stores the last cell iterator. If caching is turned on, it uses this iterator as the starting point.<p>
