The document provides an overview of the Particle Instancer, a tool in Maya Dynamics for creating instances of geometry controlled by particles. It explains the concepts of instancing and particle instancing, along with practical applications and steps to create a Particle Instancer. Additionally, it includes practical situations and an exercise involving flying lanterns.

1) OVERVIEW PARTICLE INSTANTER

4. 1.1) What is particle instanter?
THE PARTICLE INSTANTER
 Instancing?
o An instance is similar to a duplicated object but the difference is, it is not actual object.
Let's say you are in a room surrounded by 100 mirrors. If you lift one leg, many of you
in the mirror will lift one leg too. But it doesn't mean every you in 100 mirrors are
"actual" you.
o An instance contains no actual surface information, but is just a redrawn version of an
original object. The original object acts like a master to all of its instances like you in
the mirror room. Instances will be updated as the original is updated on all shading and
surface characteristics.
o Instances contain less information than duplicates so they can be handled and redrawn
faster.
 Particle Instancing
o Particle instancing is the process of using the position and behaviour of particles to
control the position and behaviour of instanced geometry. Although some complex
results can be obtained using particle instancing, it is important not to interpret it as a
full-featured behaviour animation system or flocking system. There are no behavioural
relationships between the individual instanced elements.

7. THE PARTICLE INSTANTER
o Particle Instancer Name: Optional name of the instancer node.
o Rotation Units: value is interpreted as degrees or radians.
o Rotation Order: precedence order of rotation, for instance, XYZ, XZY, or ZXY.
o Level of Detail: source geometry appears at the particle locations or whether a
bounding box or boxes appear instead.
o Geometry: The source geometry appears at the particle locations.
o Bounding Box: Displays a single box for all the objects in the instanced
hierarchy.
o Bounding Boxes: Displays individual boxes for each object in the instanced
hierarchy.
o Cycle: Select from the following options:
o None: Instance a single object.
o Sequential: Cycle through the objects in the Instanced Objects list.
o Cycle Step Unit: frames or seconds are used for the Cycle Step Size value.
o Cycle Step Size: age interval at which the next object in the sequence appears.
