Chapter 3 Three-Dimensional Transformation
The figure below illustrates the x-, y- and z-coordinate values for
each of the coordinate frames.
• In the source coordinate frame, the origin is at the center of the
image, and the x- and y-coordinates range from –4 to +4 and –3
to +3 respectively over the area of the image.
• In the target coordinate frame, the origin is at the center of the
output video space, and the x- and y-coordinates range from –4 to
+4 and –3 to +3 respectively over the area of the output video
space. When using a 16:9 aspect ratio screen, however, the
ranges are x from –4 to +4 and y from –2.25 to +2.25.
The limits for the x-, y- and z- coordinates are from –999 to +999.
