Translation and Transformation
Translation is a subset of transformation, and involves picture movement
along the X, Y, and Z axis. The picture is simply relocated to a different
place and does not change in actual size or shape.
Figure 22. Picture Translation
Transformation includes translation, and also includes these other func-
tions:
Size
Enlargement and reduction of the picture area while it remains in the same
plane in 3-D space. This is different from picture translation in the Z axis,
where the picture retains its original size, but appears smaller when moved
away, and larger when moved closer.
