Paralle
The cameras are shifted parallel to each other. Since this is a purely parallel shift, there is no
Convergence Distance control that limits your control over placing objects in front of or behind
the screen. However, Parallel introduces no vertical parallax, thus creating less strain
on the eyes.
Rig Attached To
This pop-up menu allows you to control which camera is used to transform the stereoscopic
setup. Based on this menu, transform controls appear in the viewer either on the right camera,
left camera, or between the two cameras. The ability to switch the transform controls through
rigging can assist in matching the animation path to a camera crane or other live-action camera
motion. The Center option places the transform controls between the two cameras and moves
each evenly as the separation and convergence are adjusted. Left puts the transform controls
on the left camera, and the right camera movesas the separation and convergence are
adjusted. Right puts the transform controls on the right camera, and the left camera moves as
adjustments are made to separation and convergence.
Eye Separation
Eye Separation defines the distance between both stereo cameras. Setting Eye Separation to a
value larger than 0 shows controls for each camera in the viewer when this node is selected.
Note that there is no Convergence Distance control in Parallel mode.
Convergence Distance
This control sets the stereoscopic convergence distance, defined as a point located along the
Z-axis of the camera that determines where both left- and right-eye cameras converge. The
Convergence Distance controls are only available when setting the Mode menu to Toe-In
or Off Axis.
Film Back
Film Gate
The size of the film gate represents the dimensions of the aperture. Instead of setting the
aperture’s width and height, you can choose it using the list of preset camera types in the Film
Gate menu. Selecting one of the options automatically sets the aperture width and aperture
height to match.
Aperture Width/Height
The Aperture Width and Height sliders control the dimensions of the camera’s aperture or the
portion of the camera that lets light in on a real-world camera. In video and film cameras, the
aperture is the mask opening that defines the area of each frame exposed. The Aperture
control uses inches as its unit of measurement.
