Detents 
The system defines points called detents at regular
 
intervals on the three-dimensional space. Pressing the
 
[CTR] button in the device control block sets the current
 
three-dimensional parameter values to the closest detent
 
points. 
The following shows the interval between successive
 
detents for each transformation operation mode 
(

Z-axis – 
The + direction on the
 
Z-axis is depth into the
 
image or monitor
 
screen.

Limits of three-dimensional parameters 
The following table shows the limits of three-dimensional
 
transformation parameters. The three-dimensional
 
parameters of an image change when you use the trackball
 
or Z-ring to execute a transformation. You can also
 
execute a transformation by entering parameter values
 
from the Flexi Pad.

When a value is smaller than 1, 1/Aspect or 1/Perspective (Z) is adjusted
 
to an integral value. 
 
 
Three-dimensional parameter default 
values 
Each of the transformation operation modes has default
 
values for three-dimensional parameters. If required, you
 
can return the current value to the defaults by pressing the
 
[CTR] button in the device control block twice in rapid
 
succession. 
The following shows the default parameter values for each
 
transformation operation mode.

Resetting of parameter values set in the 
source coordinate space 
In some transformation operation modes, if you switch to
 
the target coordinate space after setting up a three-
 
dimensional transformation in the source coordinate space,
