3-D Digital Effects Concepts
The Kalypso Transform Engine option provides 3-D planar image transla-
tion and transformation from within the Kalypso system. Image translation
has special basic concepts and terminology you should understand in
order to get the most out of using the option.
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 (Picture Translation
on
page 109 ).
Figure 85. 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.
Rotate — Picture rotation about the reference axis in the X, Y, and Z dimen-
sions ( Figure 86 ). Rotate is limited to ± one half revolution, and will always
take the shortest path to the new position. Rotate uses Quaternian math to
calculate the move with increased accuracy. Multiple rotations are per-
formed with the Spin function.
