[Insight-users] 3d mesh reconstruction based on 2d images

[Mark Foskey]

There are two possibilities that I can think of off hand.  The first, 
which is probably the best-tested, is to use itk::ImageToVtkImageFilter 
from

   InsightApplications\Auxiliary\vtk\itkImageToVtkImageFilter.h

to convert the binary mask to a VTK image.  Then VTK has several 
options for generating meshes, such as vtkMarchingCubes.  You may want 
to use a filter such as itk::DiscreteGaussianImageFilter to smooth the 
image slightly first.

Another option is to use the itk::BinaryMask3DMeshSource filter to 
generate a mesh, which you can then export.  That is also an 
implementation of the Marching Cubes algorithm, I believe.
