Moving in 3D Space
You do not need to use a lot of math to create most 3D effects, but you do need some basic understanding of degrees of motion and geometry, as described in this section.
 | |
Moving objects in 3D space requires an understanding of each of the 3D
effect parameters and their correct order in the effects parameters
hierarchy. For more information, see Working with 3D Effects Parameters.

In sections that discuss 3D effects, X, Y, and Z refer to the three axes or dimensions of the image that can be manipulated in the 3D effect's coordinate space.
 | |
X refers to the image's left/right direction.
|
| |
Y refers to the image's up/down direction.
|
| |
Z refers to the image's front/back dimension.

The Shape and Rotation parameters allow you to rotate the image around the X, Y, and Z axes. Note that you can rotate more than 360ádegrees (from –720 to 720 degrees) between keyframes.
The following illustration shows how angles of rotation are distributed around a circle.
The following illustration shows several rotation examples.
A positive number of degrees refers to a clockwise rotation; a negative number of degrees refers to a counterclockwise rotation. For example, a rotation of +45o will rotate the image clockwise by one-eighth of a full circle, while a rotation of –45o will rotate the image counterclockwise by one-eighth of a full circle.
