the setting values in the source coordinate space (three-
dimensional parameter values) are converted to values in
the target coordinate space (source/target conversion).
Once a conversion has taken place, the original source
coordinate space parameters do not return to their original
values when you switch back to the source coordinate
space. They are reset to zeros.
Image rotation in the source coordinate space
Source/target conversion occurs in the following operation
modes:
•
Image movement (Location XYZ)
Rotation around
the X-axis
Rotation around
the Y-axis
Rotation around
the Z-axis
•
Image rotation (Rotation)
Image rotation in the target coordinate space
Transformation Operation Modes
The following operation modes are available for three-
dimensional DME transformations. These operations are
carried out in the device control block
Dimensional Transformation Operations” (p. 169))
Rotation around
the X-axis
Rotation around
the Y-axis
Rotation around
the Z-axis
Image movement (Location XYZ)
Moves the image on the X-axis, Y-axis, or Z-axis. The
direction of movement differs depending on whether you
are manipulating the image in the source coordinate space
or the target coordinate space.
Image movement in the source coordinate space
Image rotation (Spin)
When rotating the image in Rotation mode, it may not
always be possible to achieve the kind of rotation around
an axis that you want. Combining Rotation mode with Spin
mode creates an effect that rotates the image around a
specified axis. The type of rotation differs depending on
whether you are manipulating the image in the source
coordinate space or the target coordinate space. The way
the image rotates around an axis is the same as in Rotation
mode.
Movement on the
X-axis
Movement on the
Y-axis
Movement on the
Z-axis
Rotation axis movement (Axis Location)
Moves an axis of rotation in the source coordinate space.
Rotation axis movement
Image movement in the target coordinate space
Movement on the
X-axis
Movement on the
Y-axis
Movement on the
Z-axis
Movement on the
X-axis
Movement on the
Y-axis
Movement on the
Z-axis
Image rotation (Rotation)
Rotates the image on the X-axis, Y-axis, or Z-axis. The
type of rotation differs depending on whether you are
manipulating the image in the source coordinate space or
the target coordinate space.
Image shrinking/magnification (Location
Size)
Changes the size of the whole image.
•
Because shrinking and magnification of the image in the
source coordinate space is done in three-dimensional
space, magnifying the image emphasizes the sense of
perspective.
•
Because shrinking and magnification of the image in the
target coordinate space is a conversion of the two-
dimensional image displayed on the monitor, shrinking
