<font size="2"><font face="verdana,sans-serif">You cannot save 3D image from QVTKWidget, because QVTKWidget is a 2D widget. To save 3D image you have to access vtkVolume which you added to the scene earlier. If however you have a polygonal scene which you want to voxelize, take a look here: <a href="http://www.vtk.org/Wiki/VTK/Examples/Broken/VoxelModeller">http://www.vtk.org/Wiki/VTK/Examples/Broken/VoxelModeller</a><br>

<font size="2"><font face="verdana,sans-serif">Are you trying to save 2D or 3D image? I believe your code is attempting to save rendered framebufferm which is a 2D image. MetaImage is usually used for 3D data, although it can save 2D data too. This 2D/3D discrepancy might be your problem.</font></font><div>
