Three-Dimensional
Transform Operations
Use the device control block (trackball) to execute three-
dimensional DME transforms.
Three-Dimensional Transform Basic
Operations
Channel selection buttons
Operation buttons
Device control block (trackball)
Buttons used in three-dimensional
transform operation mode
LOCAL: Enables operations in local space (selectable
simultaneously with [GLB] button).
GLB (global): Enables operations in global space
(selectable simultaneously with [LOCAL] button).
SRC (source): Enables operations in DME source space
(not selectable simultaneously with [TRGT] button).
TRGT (target): Enables operations in DME target space
(not selectable simultaneously with [SRC] button).
AXIS LOC (axis location): Moves the rotational axis of
the image in the X-axis and Y-axis directions using the
trackball, and in the Z-axis direction using the Z-ring.
ASP PERS (aspect/perspective): When the [SRC] button
is lit, this changes the aspect ratio of the image in the
X-axis and Y-axis directions independently using the
trackball, or in the X-axis and Y-axis directions
simultaneously using the Z-ring. When the [SHIFT]
button is held down and this button is pressed, the
trackball controls the skew of the image in the X-axis

and Y-axis directions.
When the [TRGT] button is lit, this changes the
perspective of the image in the X-axis and Y-axis
directions using the trackball and the distance of the
viewpoint position using the Z-ring.
LOC SIZE (location size): Changes the image size using
the Z-ring, and moves the image in the X-axis and Y-
axis directions using the trackball.
LOC (location) XYZ: Moves the image in the X-axis and
Y-axis directions using the trackball, and in the Z-axis
direction using the Z-ring.
SHIFT: Enables the [ASP PERS] button and [ROT]
button shifted-state functions.
CLR WORK BUFR (clear work buffer): Press this
button once to clear only the three-dimensional
transform parameters of the information held in the
work buffer. Press twice in rapid succession to clear all
of the parameters, and return to the default state.
ROT (rotation): Rotates the image about the X- and Y-
axes using the trackball, and about the Z-axis using the
Z-ring. Press the [ROT] while holding down the
[SHIFT] button enables rotation of the image in Spin
mode.
X, Y, Z: Restricts the axes (X, Y, Z) that the trackball and
Z-ring controls. Multiple selections are supported.
You can enter the parameter value for the
corresponding axis using the numeric keypad control
block.
CTR (center): Press this button once to changes the
values of the three-dimensional parameters currently
controlled by the trackball and Z-ring to the closest
detent values. Press twice in rapid succession to return
the parameter values to their defaults.
FINE: Enables fine control using the trackball and Z-ring
(fine mode).
Transforming an image in three-
dimensional space
1
Press the [DME] button on the device control block.
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) of the operation.
You can select more than one channel. The first
selected button becomes the reference channel, and is
lit green. Subsequent selected buttons are lit amber.
3
Using the operation buttons, select the three-
dimensional space in which to perform the transform.
[LOCAL] button: Selects local space.
[GLB] button: Selects global space.
