[vtkusers] Cut volume with freehand curve

[Justin Weber]

Here is how I do something similar with vtk in python. I have a
vtkUnstructuredGrid=uGrid

        box=vtk.vtkBox()
        box.SetBounds((X1,X2,Y1,Y2,Z1,Z2)

        clipper=vtk.vtkClipDataSet()
        clipper.SetInsideOut(0) #where 0 gives all the cells outside of the
box, and 1 gives all the cells inside the box.
        clipper.SetClipFunction(box)
        clipper.SetInput( uGrid )

        clipper.Update()

        clippedUGrid=clipper.GetOutput()

So the problem becomes, can we get the shape you want into an implicit
function?
