Foxtrot Technologies Inc. is involved in the development of many open source projects. These contributions are mostly a result of the willingness from some of our customers to contribute to the open source community.
In a recent project designing and building a custom application to design automobile parts, we used Matthias Koenig's vtkQt as a way to 3D models in vtk with Qt. However, in the process we discovered a problem that causes reference of deallocated memory. Our patched version fixes that bug and is posted here at Matthias Koenig's request.
