[Insight-users] [vtkusers] Cutting a volume

[Jafari, Kourosh]

Hi Xiapeng,

It depends on what kind of curved plane you would like to make and how interactively you would like to change it. Here is an example:

1. Use splineWidget to create a curved line.
2. Use the above splineWidget to create a parametric function by vtkParametricFunctionSource.
3. Translate the above curved line by vtkTransform in the Z direction.
4. Combine #2 and #3 by vtkAppendPolyData.
5. Use #4 as input of a vtkRuledSurfaceFilter.
6. The output of vtkRuledSurfaceFilter is a curved surface generated by connecting the vertices of the two lines that you generated in steps 2 and 3.

You also need to apply a transformation on the lines to make sure they are located in the right place in the world coordinate system.

I hope this helps.

Best,
Kourosh

Subject: [vtkusers] Cutting a volume

Dear VTK users,

I have applied vtkClipPolyData to cut a volume with a flat plane generated by vtkPlane. Now I would like to cut the volume with a customized curved plane, which means that I can change the shape and location of the plane interactively. Could you please tell me how to make a customized curved cutting plane?

Thank you very much!

Best regards,
Xiaopeng
