Example:
Image moved in X-axis direction
The direction of movement differs as follows in source
spac
e and target 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
ch
annel
Global space: Coordinates that are common to all
ch
annels
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
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
paramet
ers 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
Three-dimensional parameter setting values
The parameter value setting ranges and defaults are as
fo
llows.
