<br>
I'd like to visualize grayscale images with python, VTK and PyQt5. So, I've<br>
made this script with Qt Application and embedded<br>
QVTKRenderWindowInteractor. Please have a look into my gist<br>
<a href="https://gist.github.com/take5v/1df1e4f4222f49cf05cbf59b1f89a9ea" rel="noreferrer" target="_blank">https://gist.github.com/take5v/1df1e4f4222f49cf05cbf59b1f89a9ea</a>.<br>
<br>
The issue is that the vtkPropPicker gives wrong world coordinates while<br>
event coordinates are correct. This bug I could reproduce only on Mac Os,<br>
not on Windows and Ubuntu.<br>
<br>
I found probably a workaround that was made for c++ QVTKOpenGLWindow class<br>
which wasn't been wrapped for python:<br>

<br>
My setup:<br>
macOS Mojave 10.14<br>
python 3.6.4<br>
vtk-python 8.1.1<br>
PyQt 5.11.3<br>
