Picture Manipulator effects can also employ both source and target space
directed transforms simultaneously, which can create complex and beau-
tiful effects.
The simplest example for source and target space concerns a channel that
has been rotated while the global channel remains unchanged.
Figure 37. 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 differ-
ently, depending on whether source or target space is being used.
Figure 38. Source and Target Space Translation
If the channel is controlled by a global channel, and the global channel itself
has been rotated, an X axis translation will depend on whether the channel
itself or the global channel is being manipulated, and whether source or
target space is being used (
Figure 40 and Figure 40 ). Note that the target
translate of the channel is the same as a source translate of the global
channel.
