Rotation around Y-axis in local space
Rotation around Y-axis in global space
Three-dimensional parameters
Three-dimensional parameters are X, Y, and Z values
which define the position of an image, its axis of rotation,
the position of the virtual viewpoint of the image, and so
on.
The standard values of parameters are as follows,
depending on the aspect ratio of the monitor (4:3 or 16:9).
Values for 4:3 mode
• Origin at center of image (source space) or center of
monitor (target space)
X = 0.00, Y = 0.00, Z = 0.00
• Upper right corner of image or monitor
X = 12.00, Y = 9.00, Z = 0.00
• Lower left corner of image or monitor
X = –12.00, Y = –9.00, Z = 0.00
X-axis
–12
–9
Z-axis –
The plus direction on the
Z-axis is into the image
or monitor screen.
Values for 16:9 mode
• Origin at center of image (source space) or center of
monitor (target space)
X = 0.00, Y = 0.00, Z = 0.00

Valid values of three-dimensional parameters
The following table shows the valid range of three-
dimensional parameters for transforms. The three-
dimensional parameters of an image change when you use
the trackball or Z-ring to execute a transform. You can also
execute a transform by changing parameter values entered
on the numeric keypad control block.
