// .SECTION Description
|
|
// vtkImageCacheFilter keep a number of vtkImageDataObjects from previous
|
|
// updates to satisfy future updates without needing to update the input. It
|
|
// does not change the data at all. It just makes the pipeline more
|
|
// efficient at the expense of using extra memory.
