Particles
that do not pass any test in an event commonly are deleted or recycled through the event
until they do pass a test. Events are wired together in a flowchart style to clearly display the
path, from event to event, that the particles follow.
546 ?– chapter 12: Particles and Dynamics
Particle Flow is the event-driven particle system in 3ds Max, and it is a very comprehensive
solution to most particle system requirements. The upper-left pane in the Particle
View window in Figure 12.1 shows a partial layout of the events in a Particle Flow setup.
Events are the named boxes, operators are the gray boxes, and tests appear as yellow
diamonds. To the right of the Particle View window is a common example of one of the
several emitter types that a Particle Flow can utilize. Using Particle Flow, you can create
almost any particle-based effect, including rain, snow, mist, a flurry of arrows and spears,
and objects assembling and disassembling in a blast of particles. Unfortunately, an in-depth
examination of Particle Flow is beyond the scope of this book. However, we will familiarize
you with the fundamentals of particles in the hopes you will be inspired to learn more
in the course of your own work??”which, when you think about it, is the best way to learn
any program.
