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 moves the image in the
x-axis and y-axis directions, and the Z-
ring moves the image in the z-axis
direction.
SHIFT: While holding down this button,
pressing the [ASP PERS] button or
[ROT] button switches to the shifted
version of the corresponding function.
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): When this button is lit, the
trackball 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 enables rotation of the
image in the "Spin" mode. The
trackball and Z-ring operate in the
same manner.
X, Y, Z: These restrict which axes the
trackball and Z-ring 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.
CTR (center): Pressing this button
changes the values of the three-
dimensional parameters currently
controlled by the trackball and Z-ring
to the closest detent values.
Pressing twice in rapid succession
returns the parameter values to their
defaults.
When the VTR/disk recorder/frame
memory operation mode is enabled
LOCAL (DELAY): Press this button,
turning it on, to enter a delay value
from the numeric keypad control block.
GLB (STB OFF: standby off): Press this
button to switch to standby off mode.
