Chapter 26 Transformations, Motion Blur, and AutoAlign 805
Parameters
This node displays the following controls in the Parameters tab:
left, right, bottom, top
As their names imply, these parameters let you set the outer boundaries of the DOD.
For more information, see “ The Domain of Definition (DOD) ” on page 82.
Shear
The Shear node skews the image left and right, or up and down. Motion blur can also
be applied.
Parameters
This node displays the following controls in the Parameters tab:
xShear, yShear
These parameters let you shear the image horizontally and vertically. The sliders let you
adjust the shearing of the image anywhere between 0 and 1 (1 creates 45 degrees of
shearing), but you can enter any value you want into the numeric field.
xCenter, yCenter
These parameters let you move the horizontal and vertical position of the center point
around which all transformations occur. For example, moving the center point to the
right changes the point about which the image rotates when you adjust the angle
parameter.
motionBlur
Motion Blur quality level. 0 is no blur, whereas 1 represents standard filtering. For more
speed, use less than 1. This value is multiplied by the global motionBlur parameter.
• shutterTiming: A subparameter of motionBlur used to specify shutter length. 0 is no
blur, whereas 1 represents a whole frame of blur. Note that standard camera blur is
180 degrees, or a value of .5. This value is multiplied by the global shutterTiming
parameter.
• shutterOffset: A subparameter of motionBlur representing the offset from the current
frame at which the blur is calculated. Default is 0; previous frames are less than 0.
