to the plane of the monitor screen, and the z-axis is defined perpendicular to
the plane of the monitor screen. The coordinates do not move even if the
image moves.
Source coordinate space and target coordinate space
For example, as shown in the following figure, the image moves in a different
direction when you move it along the x-axis of the source coordinate space and
along the x-axis of the target coordinate space.
Movement along the x-axes of the source
coordinate space and target coordinate space
Local coordinate space and global coordinate space
The coordinates of an individual DME channel are called its local coordinate
space. The coordinates common to all channels are called the global coordinate
space.
By switching from local to global coordinate space, you can add new
movement to the movement of images in individual channels, and also apply
transformation effects to multiple channels that have been combined by Global
effects (page 711).
