Hi all,<br>I downloaded the VTK git nightly build today and build it and linked it with my program without problems.<br><br>I am using my own interactor style derived from vtkInteractorStyleTrackballCamera.<br>The creation of vtkInteractorStyle fails because vtkPolyDataMapper::New(); returns null.<br>
<br>Does anyone have any suggestions about how to fix this?<br><br>Thank you very much,<br>Dan<br><br>What follows is the call stack when the segmentation fault occured.<br><br>0x00007ffff2323b99 in vtkInteractorStyle::vtkInteractorStyle (this=0x246ff10) at /home/dlipsa/external/VTK/Rendering/Core/vtkInteractorStyle.cxx:64<br>
