[vtkusers] slice a volume

[WangQ]

Hello,
Thanks for the prompt response.
However, the point is that the shown volume is not from single input. The spheres inside the cylinder are generated dynamically, and included in the vtkRender one by one, i.e. each sphere has its own mapper, actor, etc. Therefore, simply using cutter or plane is unable to fulfill the slicing. 
One thing I can imagine is that if I can get the data from the renderer, I can then apply cutter or plane to slice it. But I do not know how to get the data. 
Cheers,
Chiang

Did you try to use vtkCutter class? http://www.vtk.org/Wiki/VTK/Examples/Java/Miscellaneous/vtkCutterAtenciosamente,

Hello Aashish,
I have a 3-d image like below. What I want is to cross-sectionally slice the image. I have checked the reslice class, but it needs vtkImageData as input. 
Cheers,
Chiang

Have you looked into this mapper: http://www.vtk.org/doc/nightly/html/classvtkImageResliceMapper.html
Not sure about vtkSphereSource relation to volume. Can you elaborate more?
Thanks

Hello vtkusers,I have a volume, in which there are lots of spheres by vtkSphereSource at arbitrary position, and possible a few isosurfaces. I want to slice the volume at any position along one axis, and save the slices. I tried several ways to achieve it, but since every object has its own mapper and actor. I do not know how to do it.Really appreciate for any help!Cheers,Chiang
