[vtkusers] about building the model of a series of particular areas

[Chenzhuo]

Hi,all vtkusers
If I want to build a model of a series of particular
areas in a series of medical images in BMP or JPEG
format,how should I set the pixel scalar in the
images? If I only set the scalar of boundary pixels of
the particular area a exclusive value which is
different with any other pixel in the images, can I
only get a 3D model of the particular areas?
