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 (
Figure 88 ).

Source and Target Space
The Kalypso Transform Engine uses source and target space frames of ref-
erence.
• 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. Kalypso Trans-
form Engine effects can also employ both source and target space directed
transforms simultaneously, which can create complex and beautiful effects.
