Valid values of three-dimensional parameters
The following table shows the valid range of three-
dimensional parameters for transforms. The three-
dimensional parameters of an image change when you use
the trackball or Z-ring to execute a transform. You can also
execute a transform by changing parameter values entered
on the numeric keypad control block.

Detents
The system defines points called detents at regular
intervals in three-dimensional space. You can change the
current three-dimensional parameter values to the nearest
detent point values by pressing the [CTR] button in the
device control block.
The following table shows the interval between detents
defined for each transform operation mode (see page 212).

Three-dimensional parameter default
values
Each of the transform operation modes has default values
for three-dimensional parameters. If required, you can
return the current value to the defaults by pressing the
[CTR] button in the device control block twice in rapid
succession.
The following table shows the default parameter values for
each transform operation mode.

Resetting of parameter values set in
source space
In some transform operation modes, if you switch to target
space after setting up a three-dimensional transform in
source space, the setting values in source space (three-
dimensional parameter values) are converted to values in
target space (source/target conversion).
Once a conversion has taken place, the original source
space parameters do not return to their original values
when you switch back to source space. They are reset.
Source/target conversion occurs in the following operation
modes:
• Move image (Location XYZ)
• Rotate image (Rotation)
