Local coordinate space and global coordinate 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 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
