interpolate temporal datasets
<p>
<a class="el" href="a01673.html" title="interpolate temporal datasets">vtkTemporalInterpolator</a> interpolates between two time steps to produce new data for an arbitrary T. <a class="el" href="a01673.html" title="interpolate temporal datasets">vtkTemporalInterpolator</a> has two modes of operation. The default mode is to produce a continuous range of time values as output which enables a filter downstream to request Any value of T within the range. The interpolator will produce the requested T. The second mode of operation is enabled by setting DiscreteTimeStepInterval to a non zero value. When this mode is activated, the filter will report a finite number of Time steps separated by deltaT between the original range of values. This mode is useful when a dataset of N time steps has one (or more) missing datasets for certain T values and you simply wish to smooth over the missing steps but otherwise use the original data.<p>
