Detents
The system defines points called detents at regular
intervals on the three-dimensional space. Pressing the
[CTR] button (see page 284) in the device control block
sets the current three-dimensional parameter values to the
closest detent points.
The following table shows the interval between successive
detents for each transformation operation mode (see page
271).

a) When a value is smaller than 1, 1/Aspect or 1/Perspective (Z) is adjusted
to an integral value.
Three-dimensional parameter default
values
Each of the transformation operation modes has default
values for three-dimensional parameters. If required, you
can return the current value to the defaults by pressing the
[CTR] (see page 284) button in the device control block
twice in rapid succession.
The following table shows the default parameter values for
each transformation operation mode.

Resetting of parameter values set in the
source coordinate space
In some transformation operation modes, if you switch to
the target coordinate space after setting up a three-
dimensional transformation in the source coordinate space,
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.
Source/target conversion occurs in the following operation
modes:
• Location XYZ
• Rotation

Transformation Operation Modes

The following operation modes are available for three-
dimensional DME transformations. These operations are
carried out in the device control block (trackball or
joystick). For details, see "Three-Dimensional
Transformation Operations" (page 283).
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.
