3D widget for manipulating an infinite cylinder
This 3D widget defines an infinite cylinder that can be interactively placed in a scene. The widget is assumed to consist of four parts: 1) a cylinder contained in a 2) bounding box, with a 3) cylinder axis, which is rooted at a 4) center point in the bounding box. (The representation paired with this widget determines the actual geometry of the widget.)
To use this widget, you generally pair it with a vtkImplicitCylinderRepresentation (or a subclass). Various options are available for controlling how the representation appears, and how the widget functions.
- Event Bindings:
- By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
If the cylinder axis is selected:
LeftButtonPressEvent - select normal
LeftButtonReleaseEvent - release (end select) normal
MouseMoveEvent - orient the normal vector
If the center point (handle) is selected:
LeftButtonPressEvent - select handle (if on slider)
LeftButtonReleaseEvent - release handle (if selected)
MouseMoveEvent - move the center point (constrained to plane or on the
axis if CTRL key is pressed)
If the cylinder is selected:
LeftButtonPressEvent - select cylinder
LeftButtonReleaseEvent - release cylinder
MouseMoveEvent - increase/decrease cylinder radius
If the outline is selected:
LeftButtonPressEvent - select outline
LeftButtonReleaseEvent - release outline
MouseMoveEvent - move the outline
If the keypress characters are used
'Down/Left' Move cylinder away from viewer
'Up/Right' Move cylinder towards viewer
In all the cases, independent of what is picked, the widget responds to the
following VTK events:
MiddleButtonPressEvent - move the cylinder
MiddleButtonReleaseEvent - release the cylinder
RightButtonPressEvent - scale the widget's representation
RightButtonReleaseEvent - stop scaling the widget
MouseMoveEvent - scale (if right button) or move (if middle button) the widget
- Event Bindings:
- Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkImplicitCylinderWidget's widget events:
vtkWidgetEvent::Select -- some part of the widget has been selected
vtkWidgetEvent::EndSelect -- the selection process has completed
vtkWidgetEvent::Move -- a request for widget motion has been invoked
vtkWidgetEvent::Up and vtkWidgetEvent::Down -- MoveCylinderAction
- Event Bindings:
- In turn, when these widget events are processed, the vtkImplicitCylinderWidget invokes the following VTK events on itself (which observers can listen for):
vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)
