19Three-Dimensional Transformation Operations
Chapter 11 DME Operations
2
Enter a parameter value with the numeric keypad.
The number of significant digits after a decimal point is 4.
3
Press the [ENTER] button.
The parameter value is changed, and the image changes.
To enter difference values
You can enter difference values by pressing the [+/−] button, entering the
difference from the current value, and pressing the [TRIM] button to confirm.
The [+/−] button toggles between “+” (plus) and “−” (minus) each time it is
pressed.
Resetting three-dimensional parameter values
Pressing the [CTR] button in the device control block sets the current three-
dimensional parameter values to the closest detent points.
To reset three-dimensional parameter values to the defaults for the current
transformation operation mode, press the [CTR] button twice in rapid
succession. (For details of detents and default values, see “Three-Dimensional
Transformations” in Chapter 1 (Volume 1).)
Clearing the working buffer
The working buffer is memory that holds the instantaneous state of an effect.
To clear (initialize) only the three-dimensional transform parameters in the
working buffer, press the [CLR WORK BUFR] button in the device control
block.
To clear all of the parameters in the working buffer and initialize the DME
system, press the [CLR WORK BUFR] button twice in rapid succession. It is
necessary to do this for both the local coordinate space and global coordinate
space.
As the initial DME state, you can specify whether to use the factory default
settings or user settings in the Setup menu. (See “Selecting the State After
Powering On (Start Up Menu)” (page 199).)
Graphics Display
You can display graphics such as a wire frame, coordinate axis, and a grid over
the current DME image. This makes it easier to set up transformations, because
you can operate while viewing the coordinate axes and the position of the
image in three-dimensional coordinate space. (For the types of graphics
displayed, see “Graphics Display” in Chapter 1 (Volume 1).)
