Chapter 18 Compositing With the MultiPlane Node 523
angleOfView
A subparameter of focalLength. This value is provided for convenience, and represents
the horizontal field of view of the frustum (as opposed to the vertical field of view that
the Move3D node uses), based on the current focalLength. The value of the
angleOfView has an inverse relationship to that of the focalLength parameter—raising
one lowers the other, and vice versa.
translate (x, y, z)
Transform data for the camera’s position. By default, the translate parameters are set to
expressions that automatically set their values.
rotate
Transform data for the camera’s rotation. If you keyframe rotation, the data is stored
here.
rotateOrder
The order in which rotations are executed, by dimension. Defaults to XZY.
interestDistance
This parameter defines the distance of the camera target to the camera. By default, this
parameter is set to an expression that automatically sets its value.
filmGate
The filmGate pop-up menu provides presets for setting the filmBack width and height
parameters. There are options corresponding to most standard film formats.
filmBack (width, height)
Represents the width and height of the image that strikes the virtual film, in inches.
Note: If you’re not importing camera data and you want to avoid squeezing the image
improperly, make sure the aspect ratio of the filmBack width and height parameters
matches that of the input image.
scale
Represents the size of the camera compared to the scene. Lowering this value reduces
the visible area taken in by the virtual lens, increasing the size of the scene relative to
the viewer. Increasing this value increases the visible area seen by the lens, reducing
the size of the scene relative to the viewer.
Changing the scale parameter also changes the effective focal length of the camera. For
example, if the focalLength parameter is set to 50, setting the scale to 2 changes the
effective focal length to 25. Setting the scale to 0.5 changes the effective focal length
to 100.
