3D and 2D view not consistent

[DanicaSTFC]

It could happen here, so maybe viewer issue

CILViewer/Wrappers/Python/ccpi/viewer/CILViewer2D.py

Lines 1328 to 1331 in 894fc7b

	self.camera.SetViewUp(0, -1, 0)
	if not self.axes_initialised:
	self.camera.Azimuth(180)

Change camera view

self.resetCameraToDefault()

Issue opened in iDVC, but needs to be resolved in the viewer. See TomographicImaging/iDVC#240 (comment)

This would change the camera elevation but, it doesn't work very well as the orientation marker doesn't get updated. See the VTK Text book

# do a full Elevation + 180 degrees
camera = vtk.vtkCamera()

camera.DeepCopy(self.getCamera())
camera.Elevation(180)

self.getRenderer().SetActiveCamera(camera)
om = self.orientation_marker.GetOrientationMarker()
om.Modified()
self.renWin.Render()

in the toolbar3d branch I change the position of the camera (as here) and create an animation with an orbit around the object.

Possibly what's missing is adjustCamera
