Detailed Description

Interactive manipulation of the camera.

This class is based on vtkInteractorStyleTrackballCamera, but includes extra features and event invocations to support extra features of slicer.

vtkInteractorStyleTrackballCamera allows the user to interactively manipulate (rotate, pan, etc.) the camera, the viewpoint of the scene. In trackball interaction, the magnitude of the mouse motion is proportional to the camera motion associated with a particular mouse binding. For example, small left-button motions cause small changes in the rotation of the camera around its focal point. For a 3-button mouse, the left button is for rotation, the right button for zooming, the middle button for panning, and ctrl + left button for spinning. (With fewer mouse buttons, ctrl + shift + left button is for zooming, and shift + left button is for panning.)

NumberOfPlaces

Keep track of the number of picks so for resetting mouse modes when transient pick or place mode has been selected.

Definition at line 121 of file vtkThreeDViewInteractorStyle.h.

NumberOfTransientPlaces

int vtkThreeDViewInteractorStyle::NumberOfTransientPlaces

protected

The number of "clicks" the transient mouse-modes come loaded with. Currently makes sense to set this to 1 – but we can change it if appropriate.

ShiftKeyUsedForPreviousAction

bool vtkThreeDViewInteractorStyle::ShiftKeyUsedForPreviousAction

protected

Indicates whether the shift key was used during the previous action. This is used to require shift-up before returning to default mode.
