2.11.3 Source and Target Space
The KayakDD Transform Engine 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. KayakDD Transform Engine 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.
Figure 27 Source and Target Space
In this example the source space for the channel is referenced to the picture itself
(tilted back at an angle) while the target space is referenced to the monitor screen
(straight). X axis translations will move this picture differently, depending on whether
source or target space is being used.
