Introduction
vtkCameraManipulator is a superclass for actions inside an interactor style
and associated with a single button. An example might be rubber-band
bounding-box zoom. This abstraction allows a camera manipulator to be
assigned to any button. This super class might become a subclass of
vtkInteractorObserver in the future.
Settings
These settings determine which button and modifiers the manipulator responds
to. Button can be either 1 (left), 2 (middle), and 3 (right).
button
Set/Get button association, default is 1.
shift
Set/Get whether shift key is associated with manipulator, default is 0.
control
Set/Get whether control key is associated with manipulator, default is 0.
center
Set/Get center of rotation, default is [0, 0, 0].
rotationFactor
Set/Get the rotation factor, default is 1.
manipulatorName
Set/Get the manipulator name. Default is empty string.
Methods
The following methods are abstract and must be implemented by subclasses
startInteraction()
Event bindings controlling the effects of pressing mouse buttons or moving
the mouse.
endInteraction()
Event bindings controlling the effects of pressing mouse buttons or moving
the mouse.
onMouseMove(eventX, eventY, vtkRenderer, vtkRenderWindowInteractor)
Event bindings controlling the effects of pressing mouse buttons or moving
the mouse.
onButtonDown(eventX, eventY, vtkRenderer, vtkRenderWindowInteractor)
Event bindings controlling the effects of pressing mouse buttons or moving
the mouse.
onButtonUp(eventX, eventY, vtkRenderer, vtkRenderWindowInteractor)
Event bindings controlling the effects of pressing mouse buttons or moving
the mouse.
onKeyUp(vtkRenderWindowInteractor)
Called on all registered manipulators, not just the active one. Hence, this
should just be used to record state and not perform any interactions.
onKeyDown(vtkRenderWindowInteractor)
Called on all registered manipulators, not just the active one. Hence, this
should just be used to record state and not perform any interactions.
computeDisplayCenter(vtkInteractorObserver)
Save the center of rotation in screen coordinates
