[vtkusers] How to delete set of points..?

[Rakesh Patil]

Hello Sir, If I use that logic, then i feel it will take lot of time. Two loops will come into picture.. First loop contains IDs of points which are to be deletedand second loop is the one which is in the code..So for each time, it will iterate n times for a single point ( where n is the total number of points)thus If i want to delete m points then the code has to run m*n times ..If n is in thousands (say more than 10000 or 30000) then i feel this is not an efficient one.Can it be done using vtkCutter or vtkClipPolyData or something..??ThanksRegardsRakesh Patil Original message From:"David Doria"< daviddoria+vtk at gmail.com >Date: 17 Aug 10 17:03:48Subject: Re: [vtkusers] How to delete set of points..?To: Rakesh Patil Cc: VTK Mailing List On Tue, Aug 17, 2010 at 4:37 AM, Rakesh Patilwrote:> Hello,>> I have a set of scattered XYZ points..
