Horizon
Horizon in the distance of a scene
The horizon of a scene is the edge of vision at the height of the camera, parallel
with the world coordinate plane. You can view the horizon in camera
viewports.
A camera is level when it and its target are the same height from the world
coordinate plane. In other words, the camera's local Z axis is parallel to the
world plane. When the camera is level, the horizon line is centered in the
viewport. As the camera tilts up, the horizon line lowers; as it tilts down, the
horizon line raises.
The horizon line can help you match the perspective of your scene to the
perspective of a still image. In general, matching perspective involves the
following steps:
■ Display the horizon line. Use it to help you adjust the camera and target
so they are level.
■ Display the image in the camera viewport. Use Views menu > Background
Image.
