12 PRINCIPLES OF ANIMATION.

The 12 Principles of Animation

The 12 principles of animation were created in the 30's by animators at Disney Studios. This is a series of basic rules of animation that is used as the basis for creativity and animation production at that time. These 12 principles helped the craft of animation move from being a novelty to be an art form. Were applied initially to the Disney animated classics as Snow White, in 1937, Pinocchio and Fantasia, 40, Dumbo, and Bambi in 41 in 1942.

These principles still work today, helping to create more believable characters and situations, provide a sense of reality. For 3D these principles have had to reinterpret and expand, even had to add some additional principles that support the new styles and techniques used in animation. This is poeque in the 30's, the dominant style was the cartoon narrative animation pose to pose. During this time, the techniques and styles of animation has changed dramatically.

The 12 principles have evolved to adapt to 3D animation:

-Shrunk and stretched (Squash and Stretch)

The hype, the deformation of flexible bodies. Makes for a more comic or more dramatic. Stretching is often related to the speed and inertia.

-ADVANCE (Anticipation)

Movements are anticipated, this guides the viewer's gaze. Announces surprise. Will be three steps: Anticipation (prepares us for action), the action itself and the reaction (recovery, end of the action).

-STAGING (Staging)

Representation of an idea. With this principle translate the intentions and mood of the scene at specific positions and actions of the characters. Putting on the key positions of the characters define the nature of the action. There are several staging techniques to tell a story visually, hide or reveal the point of interest, or chain actions, action - reaction are two examples.

DIRECT-ACTION POSE A POSE (straigh ahead action and pose-to-pose)

These are actually two different animation techniques. In direct action created a continuous action, step by step, to conclude an unpredictable action, and action pose to pose movements break down structured series of key poses.

Direct action is characterized by the fluidity of movement, provides a fresh look, loose and relaxed. Influences creativity.

In the action unfolds pose to pose an initial approach is a controlled animation is determined by the number of poses and intermediate poses.

You can mix these two techniques.

-Continuous action superimposed (Follow through and overlapping action)

These two techniques help to enrich and give detail to the action. In them the movement continues until the end of their course.

In the ongoing action, the character's reaction after the action tells us how the character feels.

In overlapping action, mix multiple motions, overlap and affect the position of the character.

The 3D animation is widely used continuous action, for example in dynamic simulations of clothing or hair.

-Brakes and Boot (Ease in and out on slow in and out)

Accelerate the center of the action while slow the beginning and end of it.

-Arcs (Arcs)

Using arcs to animate the character's movement we will be giving a natural appearance, as most living creatures move in curved paths, never in perfectly straight lines.

HIGH-ACTION (Secondary action)

Small movements that complement the dominant action. Are resulting from the main action. The secondary action should not be more marked than the main action.

TIME-SENSE (Timing)

It gives meaning to movement. The time it takes a character to perform an action. Interruptions in the movements. This defines also the weight of the model and the sense of scale and sizes.

5 Tips for beginners to use the Sketchup 3D visualization software

Sketch is a very intuitive 3D package that is surprisingly easy to pick up and requires no prior knowledge of 3D modeling to the teacher. Here are 5 tips for beginners.

1. When trying to rotate the geometry in a given axis can be difficult to choose the desired axis. To overcome this problem by simply drawing a rectangle on the ground plane and push / pull it in the direction of 'and' creating a simple box. This group box and move it to an appropriate area in the modeling space. The table can now be used as a way to quickly choose an axis of rotation by following these steps:

Select the geometry to rotate, select the rotate tool, move the gizmo on the box until it faces in the desired axis and then down the Shift key to maintain this orientation, the geometry resume gizmo to rotate, click once to select the axis of rotation and simply rotate the geometry and click again to end the operation.

2. By placing DWG files as a reference to a model, always make sure the front and side views, etc.. are exactly parallel and perpendicular. The best way to ensure that their rotations are accurate is writing that the values displayed in the box at the bottom right of the interface. The most common problem you'll encounter when reference images are not parallel and perpendicular is that online tools and cut a rectangle does not face properly. A common reason for this is that the face is exactly 90 degrees but the DWG is slightly off 90 degrees and the complex adjustment functions outline the points adjusted wrong, therefore 'create' faces instead of 'cut' them.

3. Use guides! Guides are an excellent feature in the modeling process outline, drawing tools, UPS shall conform to the guidelines useful ways of May. Exact dimensions can be achieved by creating a guide in the desired axis direction, and then type the exact distance you want the guide ... this process can be multiplied, then typing 'x' and a figure - for example - 'x 10', the result is that 10 guides are created with the same spacing as the only created - try it! Once you've finished - select 'Edit' - 'delete guides'.

4. Use shortcuts! When you begin to get the hang of making a sketch safe to set custom shortcuts for all tools and operations you use most often, these can dramatically speed up workflow by saving the time it takes to click between different tools in the toolbar. To change the shortcuts to choose - 'Window' - 'Preferences' - 'shortcuts'.

5. Hold SHIFT while drawing geometry restricts the tool of choice for the axis and holding down cursor keys locks the focus of their tools to a desired direction - up / down axis 'z', left for the y-axis and appropriate for the axis 'z'. This really helps speed up the modeling.
