/**
|
|
* @class vtkArrayInterpolate
|
|
*
|
|
* Computes the weighted sum of a collection of slices from a source
|
|
* array, and stores the results in a slice of a target array. Note that
|
|
* the number of source slices and weights must match, and the extents of
|
|
* each source slice must match the extents of the target slice.
|
|
*
|
|
* Note: The implementation assumes that operator*(T, double) is defined,
|
|
* and that there is an implicit conversion from its result back to T.
|
|
*
|
|
* If you need to interpolate arrays of T other than double, you will
|
|
* likely want to create your own specialization of this function.
|
|
*
|
|
* The implementation should produce correct results for dense and sparse
|
|
* arrays, but may perform poorly on sparse.
|
