<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Have a look at how the scissors tool is implemented in 3D Slicer’s segment editor module. It’s all in VTK, quite fast (creates a polydata mask and applies that to the volume),
and works for both parallel and perspective projection.<o:p></o:p></span></p>

from the volume.<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-family:"Calibri",sans-serif;color:black">I tryed vtkClipVolume and vtkCutter, they are interenting classe because you use two input functions, one for vtkImageData and another for the polydata but
these classes<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-family:"Calibri",sans-serif;color:black">are too slow, specially when we compare with other applications that make the job in a blink of eyes.<o:p></o:p></span></p>
