CameraRotated Event

To enable the Action, use the Leadtools.MedicalViewer.MedicalViewerBaseCell.AddAction(Leadtools.MedicalViewer.MedicalViewerActionType) method to add the action to the Medical3DControl. Then use the Leadtools.MedicalViewer.MedicalViewerBaseCell.SetAction(Leadtools.MedicalViewer.MedicalViewerActionType,Leadtools.MedicalViewer.MedicalViewerMouseButtons,Leadtools.MedicalViewer.MedicalViewerActionFlags) to associate the action with a mouse button.
