<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>Hi,</div><div><br></div><div>vtkPolyDataConnectivityFilter doesn't seem to support extracting connected poly components by region size, other than restricting extraction to the largest region. With our 3D scanner data, it's useful to reject connected components smaller than a certain size, as these are indicative of scan noise. Is there an existing best practice with this filter to achieve that result? The ivar RegionSizes contains the information required to perform this sort of extraction, but it is not exposed to the outside world.</div><div><br></div><div>If there is not an existing best practice, I've written a patch against 5.6.0 that adds a new extraction mode "SizeThreshold" that I'm happy to contribute.</div><div><br></div><div>Thanks,<br>Damion</div><div> </div></span></body></html>
