DME Ope

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 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.
