Animation
Showing a bunch of pictures quickly to make them seem moving.
[see page 3, Modern] approaches to animation involves changing an objects state (join, vector, color, coordinate) over time. This is most often done with something like parametric-curves.
[see page 5, Models]
Animation is divided into [see page 4, levels] depending on how many parameters and how much control we have over the animation.
| Model | Level | Meaning |
|---|---|---|
| Descriptive | low | Effect without knowledge of cause (depends on Degrees of Freedom). |
| Generative | medium | Describe cause that produces an effect. (have a few parameters which produce more parameters). |
| Behavioural | Simulate the actions of living things that respond to internal and external stimulation. |
The more we move from low-level animation models to higher-level ones the harder it is to specify the exact motions we want.
