However, now I needed to get to the values themselves, which I hope results in a 3 (Gx, Gy and Gz) sober components, each with 3 coordinates (x, y, z). This comes from my analogy that Sobel 2D produces Gx and Gy, both 2D "images".</div><div><br></div><div>I found out an example with Sobel3D in here: <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Images/ImageSobel3D">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/Images/ImageSobel3D</a></div><div><br></div><div>However, I only obtain a planar image from the x and y components (no z component in the example, since it is only a 2D image as source).</div><div><br></div><div>My question is, since I have 3D Gx, Gy and Gz components, how can I access them?</div><div><br></div><div>Any help would be much appreciated.</div><div><br></div><div>Best regards,</div><div>
