Scaling, Positioning, and Animating Cameras
Various controls allow you to scale, position, walk, and animate cameras. After you position
cameras in a project, you can select a single camera view using the Isolate command. For
more information on using the Isolate command, see Isolate.
Scaling a Camera
You can use the Scale parameter in the Properties pane of the Inspector to scale what a
camera sees. Changing the Scale value does not affect a camera’s Angle of View parameter.
Changing the Scale value only affects Framing cameras.
About Camera Scaling
To better understand camera scaling, imagine if you shrank down to only a few inches
tall. Although the world around you hasn’t changed size, it would appear to you to be
much larger. Similarly, if you grew to 50 feet tall, the world would seem smaller, even
though it hasn’t changed. Scaling a camera up or down has the same effect.
Positioning Cameras
Cameras share the same transform properties as any other object in Motion and can be
positioned in all the same ways: by using the onscreen controls and by editing parameters
in the HUD or Inspector. For more information on the onscreen controls, see 3D View
Tools. Additionally, cameras can be positioned using the Walk 3D View tool. For more
information, see Walk 3D View.
Note: As a convenience, you can move an orthogonal camera view to display the scene
from a position and orientation other than its default.
Walk 3D View
The Walk 3D View tool, located in the toolbar, allows you to position the camera in 3D
space as you would in a video game, using a keyboard-and-mouse navigation method.
If you’re using a scene camera, you can also record the movement you create using the
Walk 3D View tool, by creating keyframes. For more information on keyframing, see
Keyframing Methods.
Note: The Walk 3D View tool is available only when Active Camera, Camera, or Perspective
is selected from the Camera menu. For more information on the Camera menu, see
Camera Menu.
To use the Walk 3D View tool
1 Select the Walk 3D View tool in the toolbar.
