I think you just have to change the image dimensions in the example.

Examples/Segmentation/WatershedSegmentation1.cxx

Basically all the 2s become 3s. 

  typedef itk::RGBPixel<unsigned char>   RGBPixelType;
  typedef itk::Image<RGBPixelType, 2>    RGBImageType;
  typedef itk::Vector<float, 3>          VectorPixelType;
  typedef itk::Image<VectorPixelType, 2> VectorImageType;
  typedef itk::Image<unsigned long, 2>   LabeledImageType;
  typedef itk::Image<float, 2>           ScalarImageType;

becomes :

  typedef itk::RGBPixel<unsigned char>   RGBPixelType;
  typedef itk::Image<RGBPixelType, 3>    RGBImageType;
  typedef itk::Vector<float, 3>          VectorPixelType;
  typedef itk::Image<VectorPixelType, 3> VectorImageType;
  typedef itk::Image<unsigned long, 3>   LabeledImageType;
  typedef itk::Image<float, 3>           ScalarImageType;
