Detailed Description

3D Widget for manipulating a vtkCamera

This 3D widget interacts with a vtkCamera3DRepresentation class (i.e., it handles the events that drive its corresponding representation). A nice feature of vtkCamera3DWidget, like any 3D widget, will work with the current interactor style. That is, if vtkCamera3DWidget does not handle an event, then all other registered observers (including the interactor style) have an opportunity to process the event. Otherwise, the vtkCamera3DWidget will terminate the processing of the event that it handles.

To use this widget, you pair it with a vtkCamera3DRepresentation (or a subclass). Various options are available in the representation for controlling how the widget appears, and how the widget functions.

Mouse Event Bindings:
By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
Select and move the camera box to change the camera position.
Select and move the camera cone to change the camera view angle.
Select and move the sphere handles to change the target and view up.
Key Event Bindings:
By default, the widget responds to the following key pressed event:
'x' or 'X': set the translation constrained to X axis, or None if
already set to X.
'y' or 'Y': set the translation constrained to Y axis, or None if
already set to Y.
'z' or 'Z': set the translation constrained to Z axis, or None if
already set to Z.
'o' or 'O': remove any translation constraint.
'a' or 'A': toggle translation of both position and target, or only
one at a time.
'c' or 'C': toggle frustum visibility.
Warning
This class, and vtkCamera3DRepresentation, are second generation VTK widgets.
