The Particle instanter1) OVERVIEW PARTICLE INSTANTER

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 youin 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 anoriginal object. The original object acts like a master to all of its instances like you inthe mirror room. Instances will be updated as the original is updated on all shading andsurface characteristics.

o Instances contain less information than duplicates so they can be handled and redrawnfaster.

Particle Instancing

o Particle instancing is the process of using the position and behaviour of particles tocontrol the position and behaviour of instanced geometry. Although some complexresults can be obtained using particle instancing, it is important not to interpret it as afull-featured behaviour animation system or flocking system. There are no behaviouralrelationships between the individual instanced elements.

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.
