Figure 15.1 The HoRrORaMa!
composition in the 3D
Glasses.aep project.
There are two copies of the same clip in the HoRrORaMa! com-
position, simply offset in time. The LEFT layer will become what
viewers see out of their left eye, the RIGHT layer will be seen in
the right eye. First, select the LEFT layer and apply the 3D Glasses
effect to it. In the Effect Controls panel, change the Left View
value to the LEFT layer and the Right View value to the RIGHT
layer. The composition will now appear split with the LEFT layer
on the left half of the composition and the RIGHT layer on the
right. This is because the 3D View property in the 3D Glasses
effect is set to Stereo Pair. While this view is useful for comparing
the left view with the right view, this is primarily a working view
only. Change the 3D View property to Balanced Colored Red Blue
to complete the effect (Figs. 15.2 and 15.3 ).
Offsetting the Blue
and Red Views
You can use the
Convergence
Offset property
in the 3D Glasses effect
to control the offset of the
blue- and red-colored
views. Adjust this property
if the fi nal result has
too much depth (or not
enough) after viewing with
3D glasses. Also be aware
that the audience's distance
from the viewing surface
can also affect the 3D
depth effect.
The Bevel Alpha Effect
Before we get into the Bevel Alpha and Bevel Edges effects,
just remember again that both these pale in comparison to the
layer styles in After Effects. They should only be used when you're
going for a beveled look to 3D layers that you want to intersect
each other in 3D space.
The Bevel Alpha effect creates the illusion of 3D by adding
highlights and shadows around the edges of the layer it's applied
to. I've created a little project called Bevel Alpha.aep that you'll
