Time and Motion Flashcards
Time and Motion
Any kind of motion takes place over time.
Conceptually, time and motion are inseparable.
Can you detect motion in still and time based media?
Yes. It doesn’t take rapid frame sequence of film or animation to suggest motion. The way that we position an object can create implied motion.
Eadweard Muybridge
Known for his pioneering work on animal locomotion in 1877 and 1878, which used multiple cameras to capture motion in stop-motion photographs and his zoopraxiscope (device for projecting motion pics that pre-dated the flexible perforated film strip used in cinematography.)
Implied Motion: Static
A centered object sitting parallel to the edges of the frame appears stable and unmoving
Implied Motion: Diagonal
An object placed on a diagonal appears dynamic
Implied Motion: Cropped
An object that is partly cut off appears to be moving into or out of the frame
Implied motion: Arrows
Arrows are moving in a certain direction
Change over Time
The most obvious way to change something is to move it. But a change in position is just one way to create change. There are a lot of other ways to make things change over time.
Modes of Change
Position
Rotation
Scale
Shape
Color
Depth
Transparency
Change in Position
Every object on a two-dimensional surface has a pair of x/y coordinates. Changing the coordinates moves the object.
Note: 3-D animation also includes the z axis
Change in Rotation
Continuously altering the angle of an object creates the appearance of spinning, shaking, and other behaviors.
Change in Scale
Making an object larger or smaller creates the impression of it moving backward or forward in space
Change in Shape
Letting a line wander can produce all types of shapes: abstract, amorphous, representational
Change in Color
Color animation creates motion by sequentially illuminating or changing the color of predefined areas or objects
Change in Depth
By layering objects you can create a sense of depth.
