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.

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.
