Segmentation of Timeline
|
||
|
|
========================
|
||
|
|
|
||
|
|
.A junction between the models
|
||
|
|
The term ``Segmentation of the Timeline'' describes both a data structure and a step in the
|
||
|
|
build process, which translates the structures of the *high-level-Model* into a corresponding
|
||
|
|
graph of Render Nodes. The latter is also known as the *low-level-Model* and can be seen
|
||
|
|
as a set of preconfigured render pipelines. When such a pipeline is ``pulled''. the render
|
||
|
|
computations are invoked. The _access points_ to all these pipelines are hooked into a
|
||
|
|
_backbone_ data structure, designated as the *Fixture* -- which breaks down each top-level
|
||
|
|
Timeline into a sequence of temporal segments: what differentiates these segments is the
|
||
|
|
topology of the Render Nodes in the pipeline; whenever a change in this topology is
|
||
|
|
necessary, a new segment is started. Such a change might e.g. be caused by a transition
|
||
|
|
between two clips, which has to cover a range of some frames.
|
||
|
|
|
||
|
|
As of 2025, this part of the model is only roughly drafted, mostly using placeholder code
|
||
|
|
to achieve some level of functional integration.
