I have a doubt about my visualizer, I hope anyone can help me.
The thing is, my pcl visualizer is implemented using MSVC C++ 2010, pcl 1.6.0, vtk 5.8 and Qt 4.8 (stating with the example http://pointclouds.org/documentation/tutorials/qt_visualizer.php). In my program I receive a signal from a thread in order to update the cloud and the visualizer, this signal is received every 140ms. In general the program works fine, but sometimes a vtk windows appears with the following message :
ERROR: In C:\Projets\PCL\SuperBuild_2010_x64_vtk_qvtk\CMakeExternal\Source\VTK\Filtering\vtkExecutive.cxx, line 776

I was looking for this error but at the moment I didn´t find the solution.
