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 an imaginary point of view on the image,
and so on.
The standard values of parameters are as follows,
depending on the aspect ratio of your monitor (4:3 or
16:9).
Values for 4:3 mode
• Origin at center of image (source coordinate space)
or center of monitor (target coordinate space)
X = 0.00, Y = 0.00, Z = 0.00
• Upper right corner of image or monitor
When using SD format signals: X = 4.00, Y = 3.00, Z =
0.00
When using HD format signals: X = 12.00, Y = 9.00, Z
= 0.00
• Lower left corner of image or monitor
When using SD format signals: X = – 4.00, Y = –3.00, Z
= 0.00
When using HD format signals: X = –12.00, Y = –9.00,
Z = 0.00
Values for X-, Y-, and Z-axes (4:3 mode)
Values for 16:9 mode
• Origin at center of image (source coordinate space)
or center of monitor (target coordinate space)
X = 0.00, Y = 0.00, Z = 0.00
• Upper right corner of image or monitor
When using SD format signals: X = 4.00, Y = 2.25, Z =
0.00
When using HD format signals: X = 16.00, Y = 9.00, Z
= 0.00
• Lower left corner of image or monitor
When using SD format signals: X = 4.00, Y = 2.25, Z
= 0.00
When using HD format signals: X = 16.00, Y = 9.00,
Z = 0.00

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 numeric keypad
control block.
