Chapter 3 Compositing With the MultiPlane Node 111
cameraName
A text field that lets you rename the camera or angle to more accurately describe
your setup.
sceneScale
Scales the depth of the virtual space used to distribute the locator points that are
displayed in the Viewer (which represent 3D tracking data clouds imported from .ma
files). This parameter allows you to expand or compress the relative distance from the
camera to the tracked background plate. Adjusting this parameter lets you more easily
position layers in space when camera tracking data comes from a subject that’s either
very far away, or very close. This parameter is for reference only, and has no effect on
the data itself. The default multiPlaneLocatorScale value is 50.
Camera Transform Data
The following parameters contain transform data for the camera, as well as parameters
that determine how the image is resolved based on mathematically simulated camera
attributes such as focal length and film gate resolution. These parameters are adjusted
whether you simply reposition the camera within the 3D workspace, keyframe the
camera manually, or import a camera path or 3D tracking data from a .ma file.
Note: Many of the parameters found within the Camera tab are identical to parameters
exported by Maya. For more information, see the Maya documentation.
Lock, Unlock, Reset
Three buttons let you lock all camera parameters, unlock all camera parameters, or
reset all camera parameters.
focalLength
Sets the focal length of the camera’s virtual lens. Shake measures the focal length in
millimeters. The default focalLength is 35mm.
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.
