Background Render

[Ichthyostega]

As Lumiera Product Owner,
I want the ability to utilise available excess system capacity,
to satisfy low priority computation demands without compromising reactivity of the GUI.

practical and technical necessities

To provide an favourable user experience, several secondary and technical necessities must be satisfied without interference with ongoing user interaction. Notably indices must be (re)organised, proxy media should be precomputed, preview images for the GUI visualisation of media need to be prepared; it is even conceivable to perform some computations in advance, on a speculative base. Since the Render Engine is based on time-bound scheduling and asynchronous messaging, providing these secondary services requires to determine the available excess processing and IO capabilities, which in turn requires some degree of monitoring and self-observation of render processing.
