Is there any noticable lagging at all?<BR>

The structures include quite complex anatomy such as the skeletons with many vertices.<BR>> In my implementation (and that is nothing more than I wrote in the morning) this works 'very' interactively. For me that is real-time enough ;)<BR>> <BR>> regards,<BR>> <BR>> lars<BR>> <BR>> <BR>> -------- Original-Nachricht --------<BR>> > Datum: Tue, 4 May 2010 09:37:22 -0400<BR>> > Von: Xiaofeng Z <xf10036@hotmail.com><BR>> > An: lars-friedrich@gmx.net<BR>> > Betreff: RE: [vtkusers] Create an approximate cross-section of a RT ROI<BR>> <BR>> > <BR>> > lars,<BR>> > <BR>> > <BR>> > <BR>> > I consider the method you described a more accurate way to do it. <BR>> > Unfortunately, vtkCutter is too slow to be used in real time.<BR>> > <BR>> > <BR>> > <BR>> > Thanks for your reply though!<BR>> > <BR>> > Xiaofeng<BR>> > <BR>> > <BR>> > <BR>> > > Date: Tue, 4 May 2010 07:55:33 +0200<BR>> > > From: lars-friedrich@gmx.net<BR>> > > Subject: Re: [vtkusers] Create an approximate cross-section of a RT ROI<BR>> > > To: xf10036@hotmail.com; vtkusers@vtk.org<BR>> > > <BR>> > > Hi Xiaofeng,<BR>> > > <BR>> > > just an idea:<BR>> > > - produce a surface from the axial contours by using<BR>> > vtkVoxelContoursToSurfaceFilter (which works quite well provided your source contours are<BR>> > evenly distributed)<BR>> > > - take vtkCutter(s) with plane implicit functions that define your new<BR>> > contouring orientation(s) and cut the volume to produce new contours from<BR>> > that directions<BR>> > > <BR>> > > HTH,<BR>> > > lars<BR>> > > <BR>> > > <BR>> > > -------- Original-Nachricht --------<BR>> > > > Datum: Mon, 3 May 2010 20:12:22 -0400<BR>> > > > Von: Xiaofeng Z <xf10036@hotmail.com><BR>> > > > An: VTK <vtkusers@vtk.org><BR>> > > > Betreff: [vtkusers] Create an approximate cross-section of a RT ROI<BR>> > > <BR>> > > > <BR>> > > > Hi vtkUsers,<BR>> > > > <BR>> > > > I have a set of contours in axial orientation representing a ROI.
