<P class="MsoNormal" style="line-height:150%;"><SPAN lang="EN-US">Can anyone help me please? I have a problem with to cut (cropping) a 3D
object, which I produced by the segmentation-method “watershed and region growing”.
In the beginning I read the DICOM images with itkImageSeriesReader, then I run watershed
or region growing algorithm, in order to connect itk with vtk and a 3D object
produce and for the displaying of segmentation, I use vtkContourFilter. After
segmentation of cropping the images I use vtkBoxClipDataSet,
vtkDataSetSurfaceFilter and vtkPolyDataMapper, but the result is a black
screen. <SPAN> </SPAN>When I read the images with
vtkDICOMImageReader and then segmented with volume rendering or marching cubes,
then it works completely well. The problem arises only for watershed and region
growing Algorithm. Where is my mistake in the code, what am I doing wrong?<SPAN> </SPAN></SPAN></P>
