<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Hi,</div><div><br></div><div>I am new to VTK. I am trying to fill small holes in a mesh I created using Kinect data. I used the <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/FillHoles">example</a> code to do that. While it works fine for small meshes, it crashes for large meshes (over 150MB in size when saved in .vtk ASCII format, roughly 15,000,000 points). I am using vtk-5.6 in Ubuntu 11.10. </div><div><br></div><div>Are there any tips/suggestions to make this work for large meshes? Or is there a way I can divide the mesh into small parts, apply the filter on all the parts and combine them? <br></div><div><br></div><div>The crash message is as follows:</div><div><br></div><div>ERROR: In /build/buildd/vtk-5.6.1/Filtering/vtkPolygon.cxx, line 766<br>vtkPolygon (0xc0f9d90): ERROR: start >= end<br><br>***
