Element 1027

Element

The antler is one element of the moose head.

An element is one of two or more individual

mesh objects (that is, groups of contiguous faces)

grouped together into one larger object. For

example, if you attach one box to another, you

create one mesh object from the two b oxes. Each

box is now an

element

of the object. Any function

you perform on that object affects all its elements.

However, you can manipulate the elements

independently at the Element sub-object level.

Emitter

An emitter is an objec t that emits part icles;

particlesareborn,orfirstenterthescene,atthe

emitter’s location. By default, Particle Flow uses

the

source icon (page 2–131)

as an emitter, but

alternatively any other object in the scene can em it

particles using the

P osition Object operator (page

2–144)

End Effector

history-dependent inverse k inematics (HD IK)

(page 2–442)

, the end effector is the pivot point of

the selected child object at the end of a kinematic

chain.

The kinematic chain is a sing le branch of a

hierarchy used for animation w ith

inverse

kinematics (IK) (page 3–1052)

. The chain starts

w ith the selected child object and travels up

through ancestors until it reaches the start of the

chain. When you move the end effector, the HD IK

solver then uses IK calculations to move and rotate

all other objects in the kinematic chain to react to

the object you moved.

The end effector has two transforms: one that

connects it to its parent, and another that connects

it to the End Effector Parent. By default, the End

Effector Parent is none (equivalent to World); you

can ass ign this in the Motion panel.

Note: You can move the end effector away from

the child object, which causes the IK chain to

straighten out. When you move t he end effector

back toward the child object, joints in the IK chain

will bend again.
