Hello Eric,<br><br>Thank's for the answer.<br><br>"So, are you seeing nothing when you render your scene?"<br>Actually no, nothing appends my Polydata is not "cuted" it's exactly the same size<br><br>Then I tried InsideOutOn() and now nothing is dislplayed.<br><br>I don't know where I can be wrong.. I will try again to set the bounds manually, but not sure that's the problem..<br><br><br>By the way I also tried to use vtkExtractPolyDataGeometry that worked quit the same but it's exactly what I need..<br><br> <br> vtkExtractPolyDataGeometry * clipper2 = vtkExtractPolyDataGeometry::New();<br><br> clipper2->SetInput(myPolyData);<br> clipper2->SetImplicitFunction(myCube);<br> clipper2->SetExtractInside(1);<br> clipper2->Update();<br><br><br>Nothing is displayed...<br><br>Regards,<br>Adeline<br><br><hr id="stopSpelling">Subject: Re: [vtkusers] vtkClipPolyData with vtkBox doesn't work<br>From: emonson@cs.duke.edu<br>Date: Thu, 14 Jan 2010 14:28:52 -0500<br>CC: vtkusers@vtk.org<br>To: adeline_joli@hotmail.com<br><br>
<base>Hello Adeline,<div><br></div><div>So, are you seeing nothing when you render your scene? One thing to be careful of when using a box for your clip function is which direction the default normals of the box faces point -- this defines whether the clip leaves the inside intact or cuts out the inside of the box. Maybe this isn't the problem you're having, but you could try setting </div><div><br></div><div>clipper->InsideOutOn();</div><div><br></div><div>and see if anything shows up.</div><div><br></div><div>Otherwise, there are examples of clipping with the vtkBoxWidget and it's GetPlanes method in {vtksource}/Widgets/Testing/Cxx/BoxWidget.cxx and {vtksource}/Examples/GUI/Python/BoxWidget.py in case those could help you track down the problem or approach it in another way. </div><div><br></div><div>Talk to you later,</div><div>-Eric</div><div><br></div><div><div>
