Because the 3-D modeler is in charge of creating the integral system of a character, it is important that the specific animation variables, or "avars," are accurately made for each model. In simpler terms, these variables correspond to the character's skeletal system. In the case of a human or animal character, this refers to the actual bones in the body.
The avars become the basis for a character's movements, which should impart integrity to the required realism, surrealism or fantastic look of the animation. The movements can only become logical and accurate if these basic components of the 3-D model are created properly.
The relation between the weight and size of the 3-D model is essential in animating a character. They should always be accurate to add believability to the appearance and movement of the character. By shaping the model accurately, it is easier to maintain the right weight, size and other physical properties for it. It will also be easier to perceive the model the way it should appear in its surroundings.
As a basic guide, altering the time a model takes to move from one place to another affects how light or heavy it appears, which is important to provide the viewer the right impression about what he sees.
The speed and pacing of the model's movements provide significant details about the logical events happening on screen. A 3-D modeler should mount the model in a way that can provide smooth movement and the right speed and pacing for it.
An animation timed too far ahead of the viewer's anticipation results in faulty storytelling. On the other hand, if the animation is timed too slow, the story becomes dull and boring.
An animated character works in the same way as an actor in a live-action movie. This means that even at the earliest stage of the animation, the character's 3-D model should already be properly set up to provide movements that can invoke the best emotions for the character.
Acting out what the story requires of the character is very crucial to any animated project. Even the slightest movements are always critical to evoke the right emotions and the personality of the character.
