[vtkusers] Creating a 3D cloud of points out of an Image

[Tomás Aguado Gómez]

I searched and they suggest the use of vtkDelaunay3D, it doesn't work  
for me as my images are too big for this class to create surfaces in  
reasonable time.

For now it is Ok if I can paint coloured 3D points in positions fixed  
in a array

Thanks!!
