Three-Dimensional Transformation Operations
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.
Transforming an image in three-dimensional coordinate space
For details of three-dimensional DME coordinate space, see “Three-
Dimensional Parameter Display” (page 423).

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.
2
With the function assignment buttons, select the three-dimensional
coordinate space in which to perform the transformation.
LOCAL button:
Selects local coordinate space.
