Animation Techniques
What does "squash and stretch" refer to in animation?
The technique of deforming an object to emphasize movement, making it look more elastic and expressive.
When did cell animation first become widely used in movies?
1930's
Which law of physics explains why objects in motion tend to keep moving unless acted on by an outside force?
Newton's First Law of Motion (Inertia)
What is the difference between "frames" and "keyframes" in animation?
Frames are individual images in a sequence, while keyframes are the specific starting and ending points for an animation.
What does the term "cell animation" refer to?
A traditional animation technique where each frame is drawn on a transparent celluloid sheet.
What is "linear interpolation" in animation?
A method used to create smooth transitions between keyframes by calculating intermediate frames.
How did animators in the 1910s become more efficient?
They began using techniques like “in-betweening,” which allowed them to reduce the number of frames that needed to be hand-drawn.
How is gravity often depicted in animation?
By showing objects falling or pulling toward the ground, typically with exaggerated speed or stretch to emphasize impact.
What is "Animatio"?
A bestowing of life
What is the purpose of a "frame" in animation?
A frame is one of the individual images in a sequence that, when played quickly, creates the illusion of movement.
What is a keyframe in animation?
A frame that marks the start or end point of a transition or action.
Who is considered the "father of animation" and contributed to developing the first animated feature?
Walt Disney.
What does the principle of "timing" help convey in animation?
It helps convey the speed of actions, making movements look realistic or stylized depending on the desired effect.
When are new images created in traditional animation?
New images are created for each frame, typically 24 frames per second.
What does "streamlined animation" aim to do?
It simplifies the animation process by reducing the amount of detail in each frame, making it more efficient.
What is streamlined animation?
A technique where animators reduce unnecessary details to create a faster, more efficient animation process.
What was the first animated feature film ever created?
Snow White and the Seven Dwarfs (1937).
In physics, what is the force that causes objects to stretch and compress in animation?
Elasticity
What is the main advantage of using computer-generated animation compared to traditional hand-drawn animation?
It allows for faster production and easier manipulation of scenes and characters.
Define "Bezier curves" in the context of animation.
Mathematical curves used to create smooth transitions and movement paths for animated objects.
In animation, what is the purpose of using Bezier curves?
Bezier curves are used to create smooth, controllable paths for animation movement and object shapes.
What was the significance of the invention of the multiplane camera?
It added depth to animated scenes by allowing different layers of backgrounds to move at different speeds.
How can the law of conservation of momentum be used in animation?
By showing that the motion of objects will continue unless acted upon by external forces, like a bouncing ball that slows down due to friction.
What is a motion capture (mo-cap) system, and how is it used in animation?
A system that tracks the movements of actors and translates those movements into digital animations.
What is "linear interpolation" used for in animation software?
To generate intermediate frames between two keyframes, ensuring smooth motion between the starting and ending points.
