[vtkusers] Plotting raster data with colormap

[Nicholas Kinar]

Hello--

I am wondering if it would be possible to plot raster data using VTK in 
a similar fashion to the Matlab imagesc(X) function.  Essentially what I 
have is a (m x n) matrix of doubles, and I would like to display this 
matrix as a 2D plot with a colormap.  The colormap intensity would 
correspond to the scaled double values.  Would it be possible to set 
this up in the form of an animation, i.e. code that continues to update 
and display the plot on the screen?

Does anyone have some sample code in C/C++?  Which functions would I use 
in VTK to create such a plot?
