GLOSSARY or the most used terms in 3D animation

Hi everybody,
People often asked me the meaning of this or that word…
The truth is that it's quite dificul to see clear with all that terminology and I've noticed that some animators get confused and mix some terms.
That's why I leave you here a lexicon of the most used words which I have separated into those categories for an easy searching:

14-Post-it-Glossary

PIPELINE : Structure through which passes a shot through the studio and production.
Animatic : Animatic or Leica, audiovisual piece which mix storyboard with the audio track synchronously.
Animation : Process used by one or more animators to give the feeling of movement to images or drawings or other inanimate objects.
Atrezzo : Any object place in the stage that is not used by a character or animated.
Feedback : Constructive criticism in order to improve the work.
Fixing : Post-animation process in which are fixed collisions, penetrations or other problems.
Hook up : Or raccord, refers to the relationship between the different shots of a film, so the illusion of sequence is never broken. Each shot must be related to the previous and serve as a basis for the next one.
Layout : Stage in which the position of the characters is decided, the staging and timing as well as the angle and position of the camera is planned, where the light comes from and how shadows are cast.
Leica : Synonymous of Animatica.

Gimbal Lock : Lock of the tridimensional rotation system by overlapping two rotation axes.
GUI : The Graphical User Interface, also known as GUI (its acronyme) is a computer program that acts as an user interface, using a set of images and graphic objects to represent the information and actions available on the interface. Its main use, is to provide a simple visual environment to allow communication with the operating system of the computer.

Arcs : Usual path of a structure with joints.
Balance : Balance is when the sum of forces and momentums of all the parts of the body are canceled.
Biomecanics : Interdisciplinary area of ​​knowledge that studies the kinematic and mechanical phenomena of the living beings as a complex systems composed by tissues, solids and mechanical bodies. That's why biomechanics is interested in movement, balance, physics, the resistance, injury mechanisms that may occur in the human body as a result of various physical actions.
Body Angles : Angles formed by the line of the pelvis with shoulders.
Body Dynamics : Part of physiology that studies the activity of biological phenomena.
Breaking joints : Bending a joint in the opposite direction to its normal rotation, which create the illusion that this position looks broken. It is used to create the illusion of flexibility and make it look like a piece of flexible rubber.

Favor / Favoring : Is the fact give more influence of a pose or another during the breakdown to define the spacing.
Hold : Still pose without any kind of movement.
