Hello,

I hope this is the right forum for my question. This is my first time
with VTK.

I need some hints for the following problem:

I implemented a viewer for the presentation of spectral data. Therefore
I used the vtkImageViewer together with the vtkImageData. I get the
spectral data in form of a double valued matrix (1000,4096). The content
of the matrix and also of the vtkImageData is time dependend. This means
the content of  e.g. the 100th line is in the next time step the content
of the 99th line and so on. The first line of the array is dropped and a
new line is pushed back.

Is there a possibility for a fast implemtation? In my opinion I need the
direct access to the data array of a vtkImageData?

Thanks in advance,

Dirk
