i have this image, i will pick in the green region
http://vtk.1045678.n5.nabble.com/file/n5715963/rabbit_firasr.jpg  
when i pick in it, i will retrieve all points that belongs to the same
region (the green one), i want to create a newpolydata from this region, and
my question is: is it possible to delete all points from this newpolydata,
and fill it with other points ( which belongs at the final mesh) in to have
this image, i mean, just the green region will be like the green one in the
second image:
