Hello, everyone.
Section '2. Web Animations model overview' define the model
consisting of two parts: Timing model and Animation model.
Timing model is hierarchy of timing nodes:
* The global clock
* Timelines
* Players
* Animation nodes
For each timing node the specification gives definition and its role in
the hierarchy:
The global clock is a source of monotonically increasing time values
unaffected by adjustments to the system clock.
https://w3c.github.io/web-animations/#the-global-clock
A timeline provides a source of time values for the purpose of
synchronization.
https://w3c.github.io/web-animations/#timelines
The children of a timeline are called players. A player takes an
animation nodewhich is a static description of some timed behavior and
binds it to a timeline so that it runs. A player also allows run-time
control of the connection between the animation node andits timeline by
providing pausing, seeking, and speed control.
https://w3c.github.io/web-animations/#players
An animation node is an abstract term referring to an item in the timing
hierarchy.
https://w3c.github.io/web-animations/#animation-nodes
As you can see, the definition of animation node does not define any
additional
properties, that can be used to distinguish animation nodes from other
timing nodes.
Furthermore, the role (or function) of animation node is also not defined.
Could you provide some useful definition for animation nodes?
Something like: animation node is a placeholder
for animation model items.
Thanks,
Aleksei.
