|
|
* @brief Create an image filled with noise.
|
|
*
|
|
* 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.
