// .NAME vtkInteractorStyleImage - interactive manipulation of the camera specialized for images
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkInteractorStyleImage allows the user to interactively manipulate
|
||
|
|
// (rotate, pan, zoomm etc.) the camera. vtkInteractorStyleImage is specially
|
||
|
|
// designed to work with images that are being rendered with
|
||
|
|
// vtkImageActor. Several events are overloaded from its superclass
|
||
|
|
// vtkInteractorStyle, hence the mouse bindings are different. (The bindings
|
||
|
|
// keep the camera's view plane normal perpendicular to the x-y plane.) In
|
||
|
|
// summary the mouse events are as follows:
|
||
|
|
// + Left Mouse button triggers window level events
|
||
|
|
// + CTRL Left Mouse spins the camera around its view plane normal
|
||
|
|
// + SHIFT Left Mouse pans the camera
|
||
|
|
// + CTRL SHIFT Left Mouse dollys (a positional zoom) the camera
|
||
|
|
// + Middle mouse button pans the camera
|
||
|
|
// + Right mouse button dollys the camera.
|
||
|
|
// + SHIFT Right Mouse triggers pick events
|
||
|
|
//
|
||
|
|
// Note that the renderer's actors are not moved; instead the camera is moved.
