Summary	0002787: Slice is partially hidden in the 3D view when visualizing a transformed volume
Description	How to reproduce: Load a volume Show the slice in the 3D viewer Apply a translation of (1000,0,0) Rotate and move the scene in the 3D view => ERROR: The slice in the 3D view partially disappears (the part that is close to the camera disappears) in certain camera positions and angles It seems to be a camera clipping range issue, because it's fixed by calling cam=slicer.util.getNode("Default Scene Camera") cam.ResetClippingRange() Also, the problem does not occur if there a model is displayed in the 3D view that encloses the slice, which also indicates that the camera clipping range is not updated for the slice viewer. Note that this is not exactly the same issue as the complete slice disappearing problem described in 0002785. The differences that cam.ResetClippingRange() (or displaying a 3D model) does not resolve the complete slice disappearing issue and in 0002785 the slice completely appears/disappears (no partial visibility). Nevertheless, the root cause may be the same: some visibility related parameters of the slice viewers are not updated properly when a transform is applied on the background volume.
