Introduction
to the Traditional Principles
Disney, Chouinard
Art Institute (Old Hyperion Studio School), and Don Graham
Memo
from Walt to Don (web page link)
Don is credited
with teaching the Disney animators cause-and-effect with physical
action, thinking, emotions, etc.
Don Graham’s
classes developed the principles used to create the "illusion
of life"...
Walt required
his animators to attend the classes every week
Notes from
Don Graham lecture on animation.
Animating
Force vs. Form
If you look
at the body as a form, comprised of smaller forms (and you animate
it that way), you’ll get a lifeless form
Think of the body as a force and lead with that motion
Going
from force to force, you get life like action!
Remember, intent of the force of motion comes from the mind!
"The
mind is the pilot!" --Disney
 Animating
Balance and Thrust
Balance
and Thrust must be understood to
make the poses hold up for the audience
The Balance of the character is necessary
to making the force of the motion believable
The center line of Balance tips forward
in a forward movement and the hips stay centered to keep the Balance
The Thrust is equally important to
making the action lifelike and believable
If Balance
and Thrust are wrong, the move will
look awkward to the viewer
What
is Line of Action?
The
Line of Action is the basis for rhythm, simplicity, and direction
of animation
Visual explanation of what happens to form that has been acted
upon by force
This is the driving angle of the force that carries the motion
This direction of action exists even in characters that are standing
still
Understanding the line of action will strengthen your poses
Essential for animating scenes with more than one character, the
line of action in these scenes should compliment each other and
change as needed
What
is Path of Action?
The resulting motion or illusion
of motion created by form that has been acted upon by force
If the path of action does
not fit the character’s motion, then there will be jerks and stutters
All natural motion moves in
arcs and figure eights
The larger the arcs, the more
exaggerated the motion will be
Understanding the paths of
action, will help you define the lead of your action
What
are Internally and Externally Initiated Forces?
Externally
Initiated Force
Action, movement,
motion
This kind of
force is usually created from an external agent--say a bat hitting
the back of a character
Still, the
character initiating the bat's force has internals driving that
action
Internally
Initiated Force
Acting, thinking,
emotion
For an animator,
force is most often initiated INTERNALLY
It is "thought"
that is the creator of the force
We must know
what the thought behind the force is, before animating a character
