The [DME] button is lit amber, and the device control
block switches to three-dimensional transform
operation mode.
2
Using the channel selection buttons, select the target
channel (CH1 to CH4) for operation.
You can select multiple channels. The first selected
button becomes the reference channel, and is lit green.
Subsequent selected buttons are lit amber.
3
Select a three-dimensional space.
[LOCAL] button: Local space
[GLB] button: Global space
Both local space and global space can be selected.
[SRC] button: Source space
[TRGT] button: Target space
Either source space or target space can be selected.
4
Select a three-dimensional transform operation and
transform the image.
For details about three-dimensional transform
operations, see "Three-dimensional transform
operation mode" (page 147).
To finely adjust the setting values of parameters
Press the [FINE] button, turning it on.
The adjustment mode switches to fine mode, enabling
fine adjustment of setting values using the trackball/Z-
ring.
To restrict the parameters targeted by the
operation
Press the [X] button, [Y] button, or [Z] button, turning
it on.
This enables operation only for the selected axis using
the trackball/Z-ring.
To change parameters to the closest detent
position
Press the [CTR] button once.
For details about detents, see "Detents" (page 144).
To return the parameters to the default values
Press the [CTR] button twice. Or press and hold the
[SHIFT] button and press the [CTR] button.
For details about default values, see "Three-dimensional
parameter setting values" (page 143).
To return parameters to the initial settings
The parameters return to the initial status saved data
setting values.
The operation must be performed separately for global
space and local space.
