Function assignment buttons
Region selection buttons (DME1 to 8)
Operating buttons
Device control block (MKS-8031TB)
Buttons used when the three-dimensional
transform operation mode is enabled
LOCAL: Enable operations in the DME local coordinate
space.
GLB (global): Enable operations in the DME global
coordinate space.
The [LOCAL] and [GLB] buttons can be selected at
the same time.
SRC (source): Enable operations in the DME source
coordinate space.
TRGT (target): Enable operations in the DME target
coordinate space.
The [SRC] and [TRGT] buttons cannot be selected at
the same time. When these buttons are held down,
trackball and Z-ring operation is switched to a finer
control. (fine mode)
AXIS LOC (location): When this button is lit, the
trackball moves the rotational axis of the image in the
x-axis and y-axis directions, and the Z-ring moves the
axis in the z-axis direction.
ASP PERS (aspect/perspective): When the [SRC] button
is lit, pressing this button enables the trackball to
control the x-axis and y-axis directions independently,
and the Z-ring controls the x-axis and y-axis directions
together, to vary the aspect ratio. 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, pressing this button
enables the trackball to control the perspective of the
image in the x-axis and y-axis directions.
The Z-ring controls the distance to the viewpoint.
LOC (location) SIZE: When this button is lit, the Z-ring
controls the image size.
The trackball moves the image in the x-axis and y-axis
directions.
LOC (location) XYZ: When this button is lit, the trackball
SHIFT: While holding down this button, pressing the
Trackball
CLR WORK BUFR (clear work buffer): Press this
ROT (rotation): When this button is lit, the trackball
Z-ring
X, Y, Z: These restrict which axes the trackball and Z-ring
CTR (center): Pressing this button changes the values of

transform parameters of the information held in the
work buffer. Pressing twice in rapid succession, or

defaults.
rotates the image about the x- and y-axes, and the Z-
ring rotates the image about the z-axis.
Pressing this while holding down the [SHIFT] button

trackball and Z-ring operate in the same manner.
can control. You can select more than one.
When one of these buttons is selected, you can enter
the parameter value for the corresponding axis using
the numeric keypad control block.
the three-dimensional parameters currently controlled
by the trackball and Z-ring to the closest detent values.
Pressing twice in rapid succession or holding down
[SHIFT] and pressing [CLR WORK BUFR] button
returns the parameter values to their defaults.
With the region selection buttons, select the target
channel of the operation.
You can press several of the buttons simultaneously to
select several channels. In this case, the button that you
pressed first lights in green, while buttons pressed
subsequently light in amber.
With the function assignment buttons, select the three-
dimensional coordinate space in which to perform the
transformation.
LOCAL button: Selects local coordinate space.
GLB button: Selects global coordinate space. You
can select this button and the [LOCAL] button
simultaneously.
SRC button: Selects the source coordinate space.
TRGT button: Selects the target coordinate space.
([SRC] and [TRGT] cannot be selected at the same
time.)
