THE PERSPECTIVE EFFECTS
The Perspective effects attempt to create the illusion of 3D,
mostly with things like beveled edges and shadows. These effects
are somewhat obsolete, especially with the introduction of
Photoshop's layer styles in After Effects CS3. Layer styles allow
you to add the Bevel and Emboss effect, which is much more
powerful (and looks much better) than the bevel effects in this
However, the big problem with these layer styles is that they
prohibit layers that they are applied to from intersecting in 3D
space. So if you're looking for 3D effects to apply to 3D layers, the
Perspective effects can come in handy. Also, as we go through
this brief chapter, I'll be giving you some pointers for bevels and
shadows that will work with either the effect or the layer style.
The 3D Glasses and Radial Shadow effects are also quite unique
effects that cannot be duplicated with layer styles.
The 3D Glasses Effect
The 3D Glasses effect is a unique effect in this category, and
it typically caters to a very specifi c audience. The purpose of the
effect is to create anaglyphic video. Anaglyphic video displays off-
set red and blue colors while the viewer wears 3D glasses, which
usually have a blue overlay over one eye and a red overlay over
the other. This forces one eye to see one image and the other eye
to see another, and this creates the illusion of 3D depth.
So, in this section, I'll show you how to create an anaglyphic
video. Chances are you won't be creating a 3D horrorama mon-
ster fl ick any time in the near future, but this look is so retro and
recognizable, you may fi nd it useful. To follow along with me,
open up the After Effects project 3D Glasses.aep from the Chapter
15 folder of the exercise fi les. This project contains a clip from the
public domain horror classic, Night of the Living Dead. Who bet-
ter than zombies to teach us about creating anaglyphic video?
