Axis Location
The axis location of the channel determines the center point of translations,
spins, and rotations for that channel. You can move the axis to a new loca-
tion to change the behavior of that channel. The axis location can be within
or outside the screen area.

Source and Target Space
The Kayenne XL Package Digital Picture Manipulator uses source and
target space frames of reference.
•
Source space for a control channel uses that channel’s coordinate
system for reference.
•
Target space for a channel uses the next higher level’s coordinate
system for reference.
Being able to use both source and target space can help make effects editing
easier. One frame of reference may offer a simple and easy to understand
context for a picture transform, while in another frame of reference the
same transform may be difficult to understand and control. Kayenne XL
Package Digital Picture Manipulator effects can also employ both source
and target space directed transforms simultaneously, which can create
complex and beautiful effects.
The simplest example for source and target space concerns a channel that
has been rotated while the global channel remains unchanged.
