The Simulation effects are pound for pound the most powerful
effects in After Effects. They attempt to recreate real-world cir-
cumstances and behaviors, such as explosions, caustics, and
other particle effects. The Simulation effects, though needing a
learning curve (and render time) usually steeper than for most
effects in other categories, can take the art that you produce in
After Effects to a completely new level. Because of their over-
whelming complexity, we're not going to cover these effects in
extreme detail. Effects like Particle Playground could probably
have an entire book written about them alone. My attempt here
is to spark your creativity, give you a solid foundation, and give
you enough information to learn the minutiae on your own.
The Card Dance Effect
The Card Dance effect is the more powerful sibling to the Card
Wipe effect, discussed later in Chapter 20. For more information
on most of the properties here (the ones in common with Card
Wipe), consult Chapter 20. And while you're leaping ahead to
brush up for the Card Wipe effect, you might also want to jump to
Chapter 23 (the chapter on using maps) because the real power
and benefi t of the Card Dance effect is the way it uses maps to
control properties.
The Card Dance effect turns a layer in a bunch of cards. This
may seem simplistic or even pointless, but there are such pow-
erful parameters here, that this effect should not be ignored. We
can use maps (movies even!) to control how various properties
of the cards behave. We can control the width and height (and
therefore, the size) of the cards, making them more like tiny dots
if we desire.
Another of the extremely powerful aspects of this effect is that
it operates in 3D. As with the Shatter property covered later in
