vtkTemporalInterpolator Class Reference
#include <vtkTemporalInterpolator.h>
Detailed Description
interpolate temporal datasetsvtkTemporalInterpolator interpolates between two time steps to produce new data for an arbitrary T. vtkTemporalInterpolator 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.

Member Function Documentation
| static vtkTemporalInterpolator* vtkTemporalInterpolator::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkTemporalDataSetAlgorithm.
| virtual const char* vtkTemporalInterpolator::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkTemporalDataSetAlgorithm.
| static int vtkTemporalInterpolator::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

| void vtkTemporalInterpolator::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
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 vtkTemporalDataSetAlgorithm.
| virtual void vtkTemporalInterpolator::SetDiscreteTimeStepInterval | ( | double | ) | [virtual] |
If you require a discrete number of outputs steps, to be generated from an input source - for example, you required N steps separated by T, then set DiscreteTimeStepInterval to T and you will get TIME_RANGE/DiscreteTimeStepInterval steps This is a useful option to use if you have a dataset with one missing time step and wish to 'fill-in' the missing data with an interpolated value from the steps either side
| virtual double vtkTemporalInterpolator::GetDiscreteTimeStepInterval | ( | ) | [virtual] |
If you require a discrete number of outputs steps, to be generated from an input source - for example, you required N steps separated by T, then set DiscreteTimeStepInterval to T and you will get TIME_RANGE/DiscreteTimeStepInterval steps This is a useful option to use if you have a dataset with one missing time step and wish to 'fill-in' the missing data with an interpolated value from the steps either side
