// .NAME vtkImageNoiseSource - Create an image filled with noise.
|
|
// .SECTION Description
|
|
// vtkImageNoiseSource just produces images filled with noise. The only
|
|
// option now is uniform noise specified by a min and a max. There is one
|
|
// major problem with this source. Every time it executes, it will output
|
|
// different pixel values. This has important implications when a stream
|
|
// requests overlapping regions. The same pixels will have different values
|
|
// on different updates.
