monitor screen. The coordinate axes do not change
even if an image moves.
Source space
Example:
Image moved in X-axis direction
The direction of movement differs as follows in source
space and target space.
Source space
Local space and global space
There are two types of DME coordinate space: local space
and global space.
Local space: Coordinates that are local to each DME
channel
Global space: Coordinates that are common to all channels
By switching from local space to global space, you can add
additional movement to the movement of images in
individual channels, and also add transform effects to
multiple channels that have been combined using global
effects.
Example:
Rotation around Y-axis
Rotation around Y-axis in local space
Rotation around Y-axis in global space

Three-dimensional parameters
Three-dimensional parameters have X, Y, and Z values
which define the position of an image, its axis of rotation,
the position of the virtual viewpoint of the image, and so
on.
On a 16:9 monitor screen, the reference values of
parameters for the image (source space) and screen (target
space) are as follows.
Center of image or screen:
X = 0.00, Y = 0.00, Z = 0.00
Upper right corner of image or screen:
X = 16.00, Y = 9.00, Z = 0.00
Lower left corner of image or screen:
X = –16.00, Y = –9.00, Z = 0.00
X-axis
–16.00
–9.00
Z-axis –
The Z-axis direction is + behind the image or screen,
and – in front of the image or screen.
Three-dimensional parameter setting values
The parameter value setting ranges and defaults are as
follows.
