Dear, all:<br><br>I extract a surface of one object from 3D ultrasound image, but there are many points on extracted surface (more than 300,000). So I want to sampling half or 25% representative points from the whole point set. Then I tried vtkShrinkPolyData method and set shrink factor as 0.25, but the number of points from shrinked result is not changed compared with the whole point set. Does anyone have any ideas about my purpose ?<br>
<br>Thank you for your help!<br clear="all"><br>-- <br><br> ---------------------<br>Best Regards!<br><br>===============================================<br>Rong Xu, Ph.D Student<br>Ohya Lab<br>Graduate School of Global Information
