[vtkusers] using an RGB value to make an 3D view of a bitmap

[Dave Parrott]

Hi,

I am trying to think of a pipeline to use a bitmap source (bmpreader) and an 
RGB value to make a 3D view of the bitmap.  The height of the 3D view of the 
bitmap at different points will be based on how close the color at that point 
is to the given RGB value.  So it will basically be a height field based on 
two different RGB values (those from the bmp and the given RGB value).

If anyone has any ideas of a good pipeline, let me know.

thanks,

PS thanks for the help on the vtkAXES question, I wound up just using a 
linesource.
