[vtkusers] Rotate vtkCubeAxesActor

[Michka Popoff]

Hi

thank you for you answer. I found the following test : Rendering/Annotation/Testing/Cxx/TestCubeAxesOrientedBoundingBox.cxx.
Is this the test you ment ? From the code I see that I will have to use the SetAxisBaseFor methods and define the vectors by myself, which should be easy to do. (SetAxisBaseFor is not aviable in vtk5 so I suppose it was added since then).

Now I have to reinstall the latest vtk from source, but I am not sure how to do it, I downloaded the latest master from git, I know how to install vtk 5.10.1 with Python / PyQT wrapping, but the latest master has no VTK_WRAP_PYTHON_SIP nor VTK_USE_QT options in ccmake, so for the moment I am stuck.

Here is a minimal example (in python with PyQT) to show you what I want to achieve. Adding or removing the RotateZ(45) gives twice the same result …
