[vtkusers] accessing surface(voxel) data

[LeeWoojin]

Hello vtk users.
 
 
I want to access the voxel data.
 
For example, when I use the vtkContourFilter like Marching cube algorithm,
 
how can I access the surface data?
 
I want to know voxel's position and normal information.
 
How can I access...?
 
I used Example/Medical/Cxx/Medical3.cxx 
 
 
Sincerely,
 
Lee Woo-jin
