[vtkusers] Geometric and ImageData in 2D

[Dário Oliveira]

Hi Shekhar and all,

The example you gave me mix geometric and image data (as far as I understood
it actually creates some geometric data from the imageData given, and then
merge this two geometric data), but it just works in 3D viewing. I am trying
to visualize vtkImageData, mixed with vtkPolyData ( or an other geometric
data ) together, slice by slice. I don't think it is impossible, once the
position, origin, and other important stuff for the positioning of the
geometric data, are present on the imageData structure, but until now I
havent succeeded.

Any ideas?

Thanks!

Dário.
