By default, newly created Motion projects are 2D, planar environments. When you add a scene camera and convert your project to a 3D environment, the following occurs:
A third dimension (depth) is activated in the Canvas, represented by the Z axis.
A camera object is added to the Layers list and to the Canvas (as a wireframe icon that you can drag like any other object in Motion). Like a real-world camera, a Motion scene camera lets you frame a custom point of view during your sequence. And like a real camera, a Motion scene camera can be static or set into motion to create elaborate tracking shots.
Controls become available in the Inspector for adjusting your camera’s angle of view and other properties. See Controls in the Camera Inspector.
3D overlays become available in the Canvas to help you view and arrange your 3D elements. See View 3D overlays.
Additional reference views (called reference cameras) become a available so that you can see your 3D project from various angles (from the front, back, sides, and so on). See About cameras and views.
A group of camera behaviors becomes available, allowing you to apply sophisticated animated camera moves. See Add Camera behaviors.
