[vtkusers] How to create a Image mapper to display seismic wiggles

[rodrigo]

Dear List,

I want to create a new image mapper to display seismic data as wiggles (here
is an example of how wiggles look like
http://www.sub-surfrocks.co.uk/images/pat.png). And I was hoping that
someone could give me some guidelines on how to do that in a efficient way.

Basically, what I need to know is how to do a mapper that draws 2d lines and
filled 2d polygons based on a vtkImageData with z = 0 and a scalar as
amplitude (2d data)


Thanks in advance,

Rodrigo
