1、During initialization, the default value of vtkAnnotatedCubeActor is +z. It needs to be operated to display normally. How do I refresh the state?
2、In the volume image in the lower right corner, the +z plane is displayed by default after initialization. How to set other planes to be displayed by default?
I think that’s a bug with the orientation widget. Those views aren’t all looking down +Z; if you click in the scene, the orientation widget corrects itself.
For 2), you need to get the view3D active camera and set the camera position manually to reorient the default camera (e.g. view3D.renderer.getActiveCamera().setPosition(...) near line 360 of the example)
