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><span class="ecxecxApple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><div>------------------------------------------------------</div><div>Eric E Monson</div><div>Duke Visualization Technology Group</div><div><br class="ecxecxwebkit-block-placeholder"></div></span></div><br><div><div>On Jan 14, 2010, at 12:29 PM, Adeline Joliet wrote:</div><br class="ecxecxApple-interchange-newline"><blockquote><span class="ecxecxApple-style-span" style="border-collapse: separate; font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><div class="ecxecxhmmessage" style="font-size: 10pt; font-family: Verdana;">Hello,<br><br>I'm trying to cut un polydata using vtkClipPolyData with a vtkBox as implicit function.<br><br>my Polydata is simply a rectangle (x = 100, y = 50, z= 20).
