Chapter 21 3D compositing 918
Note: If two groups are coplanar (occupy the same plane), they are composited in layer order,
regardless of whether the objects’ parent is a 2D group or 3D group. In a 2D composite, all
objects are coplanar.
3D workspace and views
3D workspace and views overview
In a 3D workspace, everything is seen from the viewpoint of a camera. The default views
presented in the 3D workspace are reference cameras that can be used and manipulated to help
place and animate objects but are not used for rendering output. To render from one of the
camera views, you must create a scene camera. For more information on cameras, see
Cameras
overview on page 928.
There are several view layouts, with each layout consisting of an arrangement of viewports. Each
viewport displays the scene from the point of view of a camera. Reference camera views have a
specific default position and orientation.
There are two types of reference cameras:
•
Orthographic
•
Perspective
An orthographic camera views the scene by looking straight down one of the world axes: X, Y,
or Z. The default orthographic cameras do not appear in the Layers list, Timeline, or Canvas. The
Front and Back cameras look straight down the Z axis. The Top and Bottom cameras look straight
down the Y axis. The Left and Right cameras look straight down the X axis.
Orthogonal camera view with no rotation
Orthographic cameras do not show perspective. Perspective cameras—and scene cameras that
you add to a project—distort the view the way a real-world camera would.
