Re: [Paraview] Moving slice with particle

Try this:

input = self.GetInputDataObject(0, 0)
inp_copy = input.NewInstance()
inp_copy.ShallowCopy(input)
inp_copy.UnRegister(None)
cutter = vtk.vtkCutter()
plane = vtk.vtkPlane()
plane.SetOrigin(0,0,0)
plane.SetNormal(0,1,0)
cutter.SetCutFunction(plane)
cutter.SetInput(inp_copy)
cutter.Update()
self.GetOutputDataObject(0).ShallowCopy(cutter.GetOutputDataObject(0))

or even better:

input = self.GetInputDataObject(0, 0)
origin = self.GetInputDataObject(0, 1).GetPoints().GetPoint(0)
inp_copy = input.NewInstance()
inp_copy.ShallowCopy(input)
inp_copy.UnRegister(None)
cutter = vtk.vtkCutter()
plane = vtk.vtkPlane()
plane.SetOrigin(origin)
plane.SetNormal(0,1,0)
cutter.SetCutFunction(plane)
cutter.SetInput(inp_copy)
cutter.Update()
self.GetOutputDataObject(0).ShallowCopy(cutter.GetOutputDataObject(0))

Re: [Paraview] Moving slice with particle

2010-02-22 Thread Thorsten Hater


Here my probably faulty python code:

slice = vtk.vtkCutter()

plane = vtk.vtkPlane()

plane.SetOrigin(0,0,0)

plane.SetNormal(0,1,0)

slice.SetCutFunction(plane)

slice.SetInput(field)

slice.Update()

out.SetFieldData(slice.GetFieldData())


The result is an empty Output Window popping up along with an empty 
output field.

The python vtk module does not export ExtractVOI or ImageSlice filter,
the generic cutter does not work for me.
If I import paraview.simple a new connection pops up and PV itself
is messed up,
so I can't use simple's Slice. Can I work around this behaviour?

Re: [Paraview] Moving slice with particle

2010-02-19 Thread David E DeMarle

I just wrapped servers/filters (where vtkPVExtractVOI and
vtkPVImageSlice reside) the other day.

So, to use them you will need to use paraview cvs and import pvfilters
in your script.

Re: [Paraview] Moving slice with particle

2010-02-19 Thread Thorsten Hater

Thanks for this! But contrary to my earlier optimism it seems not so 
easy to
use a slice filter in a programmable filter (I played mostly with the 
pvpython

 up to this point)
The python vtk module does not export ExtractVOI or ImageSlice filter,
the generic cutter does not work for me.
If I import paraview.simple a new connection pops up and PV itself is 
messed up,

so I can't use simple's Slice. Can I work around this behaviour?

Re: [Paraview] Moving slice with particle

2010-02-18 Thread Berk Geveci

It is definitely doable with the programmable filter although not as trivial
as it would be with a tool like VisTrails. The programmable filter can
accept multiple inputs. You could use the point from on of its inputs to
setup the parameter of an internal slice filter - which requires importing
the vtk.graphics module. If you can't figure it out, let me know, I'll help.
