Cameras
When setting up and animating a 3D scene, the metaphor of a camera is one of the most
comprehensible ways of framing how you want that scene to be rendered out, as well as
animating your way through the scene. Additionally, compositing artists are frequently tasked
with matching cameras from live-action clips, or matching cameras from 3D applications.
To accommodate all these tasks, Fusion provides a flexible Camera3D node with common
camera controls such as Angle of View, Focal Length, Aperture, and Clipping planes, to either
set up your own camera or to import camera data from other applications. The Camera3D node
is a virtual camera through which the 3D environment can be viewed.
A camera displayed with onscreen Transform controls in the viewer;
the Focal Plane indicator is enabled in green.
Cameras are typically connected and viewed via a Merge3D node; however, you can also
connect cameras upstream of other 3D objects if you want that camera to transform along with
that object when it moves.
Quickly Viewing a Scene Through a Camera
When you’ve added a camera to a scene, you can quickly view the scene “through the camera”
by setting up the following.
To view the scene through the camera:
1 Select the Merge3D node that the camera is connected to, or any node downstream of
that Merge3D.
2 Load the selected Merge3D or downstream node into a viewer.
3 Right-click on the axis label in the bottom corner of the viewer and choose the
camera name.
The viewer’s frame may be different from the camera frame, so it may not match the true
boundaries of the image that will be rendered by the Renderer3D node. If there is no
Renderer3D node added to your scene yet, you can use Guides that represent the camera’s
framing. For more information about Guides, see Chapter 8, “Using Viewers.”
