Hi all,
last week I've been working on asynchronous implementation of
rendering. I've managed to apply it within map canvas, so the user
experience has improved greatly: the user can freely browse the map
even if the rendering is active, the map is continuously updated in
time intervals from the intermediate results of rendering. So now huge
datasets can be navigated in QGIS seamlessly.
But there are still many unsolved problems with the threaded
implementation of rendering which I've been intentionally ignoring -
these are related to synchronization of threads and some will be
probably tough. I'm going to address the issues in the upcoming weeks.
I'm not blocked on any particular thing.
For those interested, a more verbose report is available on the
project wiki page:

Regards
Martin
