2 min read•july 25, 2024
brings life to animation, making characters and objects move naturally. It's all about different parts moving at their own pace, creating fluid motion that feels real. This technique adds depth and complexity to animations, making them more engaging and believable.
Primary actions drive the main movement, while support and enhance. Think of a character jumping (primary) with arms swinging (secondary). This hierarchy of movement creates rich, layered animations that capture the nuances of real-world motion.

- Parts of character or object move at different rates creating more natural fluid motion
- Adds realism and enhancing illusion of life avoiding stiff robotic movements
- Often occurs alongside and drag contributing to overall flow and continuity
- Examples: Flowing cape on superhero, bouncing ponytail during run
Primary vs secondary actions
- Primary actions drive overall animation main movement or intent (character jumping)
- Secondary actions support primary adding depth and complexity (arms swinging during jump)
- Identify key elements in complex animation determine main action recognize supporting elements
- Establish hierarchy of movements ensure secondary actions don't overshadow primary
- Examples: Primary (walking), Secondary (swinging arms, blinking)
Overlapping action for secondary elements
- Clothing animation consider fabric weight and stiffness animate loose parts with slight delay
- Hair animation account for length texture and style animate from root to tip with progressive delay
- Other elements include jewelry accessories props tails wings or appendages
- Use and for natural movement vary speeds for different parts of object
- Examples: Billowing cloak, swaying grass in wind
Character-environment interactions through overlapping
- Character-to-character interactions consider weight transfer and balance shifts animate reactive movements
- Simulate appropriate physics for different surfaces (ice, mud)
- Animate environmental elements affected by character movement (rustling leaves, splashing water)
- Build up to contact with anticipatory movements continue motion past point of interaction
- Adjust and based on object size and density use for impact
- Examples: Character slipping on ice, heavy footsteps in sand
Key Terms to Review (20)
Anticipation: Anticipation is a fundamental animation principle that involves preparing the audience for an action about to take place. It enhances the storytelling by creating a sense of expectation, making the subsequent movement more believable and engaging. By incorporating anticipation, animators can effectively set up actions, allowing viewers to follow along more intuitively and emotionally.
Cartoon animation: Cartoon animation is a form of visual storytelling that involves creating animated images, often using exaggerated features and vibrant colors, to convey humor, emotion, and narrative. It combines artistic creativity with the principles of animation, such as timing, movement, and character design, to produce entertaining sequences. This style allows animators to depict fantastical scenarios that might not be feasible in live-action formats while engaging audiences through memorable characters and dynamic storytelling techniques.
Ease-in: Ease-in is an animation technique that gradually accelerates an object from a stationary state to its maximum speed, creating a smoother transition and more natural movement. This method is crucial for achieving fluidity in animations, helping to convey weight and realism while enhancing the viewer's emotional connection to the animated elements.
Ease-out: Ease-out is an animation principle where the motion of an object gradually slows down as it approaches its final position. This technique creates a more natural and fluid movement, as it mimics the way objects in the real world come to a stop, allowing for smoother transitions and a polished look in animations.
Follow-through: Follow-through refers to the continuation of motion that occurs after the primary action has taken place, helping to create a more realistic and fluid animation. This principle is essential for conveying the weight and momentum of characters and objects, making their movements feel believable and engaging.
Gesture: In animation, gesture refers to the dynamic pose or movement of a character that captures their action and emotional state. It serves as a quick representation of the character's intention, attitude, and mood, allowing animators to convey a lot of information through simple movements. Gesture is essential in bringing life to characters, and it plays a crucial role in overlapping actions, solid drawing principles, and creating distinct silhouettes and shapes.
Inertia: Inertia is the tendency of an object to resist changes in its state of motion. In animation, this principle helps convey realistic movement and physicality, as characters and objects don’t just start or stop instantly but rather have a natural flow based on their mass and the forces acting upon them. Understanding inertia allows animators to create more believable weight, impact, and timing in their work.
Momentum: Momentum in animation refers to the quantity of motion an object possesses, determined by its mass and velocity. It plays a crucial role in creating believable actions, as it affects how characters and objects move through space, making their movements feel more dynamic and realistic.
Onion Skinning: Onion skinning is a technique used in animation that allows animators to see multiple frames at once, helping them to create smooth transitions between movements. By displaying the previous and next frames as semi-transparent overlays, animators can ensure that actions flow seamlessly and maintain consistency in character motion and timing. This technique plays a crucial role in developing overlapping actions and is essential for mastering both traditional and digital animation practices.
Overlapping action: Overlapping action refers to the animation technique where different parts of a character or object move at different rates, creating a more realistic and fluid motion. This principle enhances the believability of movement by ensuring that not all elements of a character or object follow the same timing, which helps to convey weight, flexibility, and natural behavior.
Pixar: Pixar is a renowned animation studio known for its groundbreaking work in computer-generated imagery (CGI) and storytelling. The studio revolutionized animation by creating emotionally resonant characters and compelling narratives, which have had a significant influence on various aspects of animation, including the implementation of overlapping action, timing and spacing for comedic or dramatic effect, and character personality development.
Secondary actions: Secondary actions are the movements or behaviors that accompany and enhance the main action of a character, helping to add depth and realism to animations. These actions support the primary movement, making it more believable and engaging by showcasing the natural flow and consequences of the main action. By introducing secondary actions, animators can create a more dynamic visual experience that captures the audience's attention and conveys personality.
Secondary Motion: Secondary motion refers to the additional movements that occur in response to the primary motion of an object, adding realism and depth to animation. This kind of motion emphasizes the natural behavior of objects, making animations more believable by mimicking how elements like hair, clothing, and other parts react when a character or object moves. By incorporating secondary motion, animators enhance the overall fluidity and connection of actions within an animated scene.
Spacing: Spacing refers to the distance between frames or key poses in animation that affects the timing and flow of movement. It plays a crucial role in conveying the speed, weight, and overall feel of an animated action, helping to create a more engaging and believable animation.
Squash and Stretch: Squash and stretch is a fundamental animation technique that creates the illusion of weight, volume, and flexibility in animated objects or characters. This principle allows animators to give life to their creations by exaggerating their movements, making them appear more dynamic and believable while enhancing their personality.
Stop Motion: Stop motion is an animation technique where objects are physically manipulated in small increments between individually photographed frames, creating the illusion of movement when the series of frames is played as a continuous sequence. This technique allows for unique storytelling and creativity, often employing various materials and styles to bring characters and scenes to life.
Timing: Timing in animation refers to the placement and duration of frames that define the motion and emotional impact of animated sequences. It affects how viewers perceive speed, weight, and realism in animation, connecting directly with principles that enhance storytelling and character expression.
Tweens: Tweens, short for 'in-betweens,' are the frames or images generated between two keyframes in animation to create smooth transitions and motion. They help fill in the gaps and make animations fluid by interpolating the movement of objects or characters from one point to another. By adjusting the timing and spacing of tweens, animators can achieve various effects, such as overlapping action or enhancing comedic timing.
Walt Disney: Walt Disney was an American film producer, director, screenwriter, voice actor, and entrepreneur, renowned for pioneering the animation industry and co-founding The Walt Disney Company. His vision transformed the landscape of 2D animation in both film and television, setting the foundation for modern animated storytelling.
Weight: In animation, weight refers to the perceived heaviness or lightness of an object or character, affecting how they move and interact with their environment. It plays a crucial role in creating believable movement by influencing the speed, timing, and physicality of animations. Understanding weight helps animators convey emotions and intentions through movement, making the animation feel more alive and relatable.
