Figure 8.3. Displays
A display is the equivalent of projectors or screens in 3D mode. It is an output that can
be connected to a player. In 2D mode, the concept of display is more abstract than in
3D mode; it doesn't matter if the physical output is a projector or a screen. A display is
defined by its resolution, along with its position in the scene and rotation.
Because all units in 2D mode are pixels, the resolution of a display can be defined both
in canvas pixels and native pixels. This is necessary to emulate different sizes of displays
with the same resolution. For instance, two HD screens of different physical sizes can
be connected to your scene's displays, but if you want to have media transitioning
between the screens that keep the same physical size, one display will need to be bigger
in your scene, even if they have the same native resolution. The size in pixels in the
scene is defined as the Resolution in Canvas. By default, the native and canvas resolutions
are the same. To have different values, uncheck the "Use Native Resolution" check box.
A display's properties can be modified in the Properties pane. The position, rotation,
and size (if Use Native Resolution is unchecked) can also be modified by using an adorner
in the Viewport, the same way as 2D media.
8.1.3

Controls

When in 2D mode, the controls in the Viewport are slightly different than in 3D mode.
The Viewport can only be panned or zoomed. The mouse controls for those actions are
the same, however the middle-mouse-button click-and-drag pans the Viewport, and
the middle-mouse-wheel zooms in the Viewport. Use the left-mouse click to make se-
lections. A right-mouse click opens a contextual menu based on the selected elements.
