vtkAreaPicker
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The vtkAreaPicker does not seem to work properly for actors that have transformations applied. The bug was reported in and a patch published in 2008 but it does not seem to have made its way into the code base and the bug seems to have disappeared. Its a simple fix and would be a great improvement to an excellent framework. Here is a link to the patch I found.
