Hello, everyone! I am happy to present the Synfig weekly report #34.
Last week we’ve got first results of optimization work done by Ivan Mahonin. The software renderer was heavily reworked and now it delivers 150-300% speed boost for vector artwork rendering. See the infographics below for details.
And yes, surely there is still a lot of room to improve.
For example, in the process of discussing the results with Gerald Young, we have found that it’s possible to get even better speed by disabling tile rendering. In this case Synfig uses only one CPU, but (surprise!) the time results are better.
So, we are considering to drop tile rendering and think how to utilize the remaining CPU power. For example, we can render several neighbor frames in parallel to current. In addition to that it would be nice to cache already rendered frames for current view. Also, we can have a background rendering for idle time. We have 8-10 fps on non-tiled renderer with current test file (utilizing just one CPU). If we will use 4 CPUs to render several frames at once, then animation playback at 24 fps becomes reality. That way the Preview Dialog would become a history.
I was discussed this idea with Ivan and he said that’s certainly possible, but the current implementation of rendering system doesn’t provide isolation for rendering several frames in parallel (even an ordinary user can notice that: just try to launch a preview and edit something on the workarea while it’s rendering - you’ll get damaged image on the workarea or damaged rendering). So, implementing this would require a significant rework for internal timeline-layer model. Although this might require some time, Ivan still mentions that as possible.
Besides that, we still have a lot of other components pending for optimizations - such as raster filters (blur, distorts, etc).
This is a good place to mention that our fundraising campaign for next month have only 8 days to go and it’s only at 44% now.
You can help us to continue the full-time development in next month by contributing to campaign or spreading a word. Your help is much appreciated!
As part of this report I couldn’t avoid mention of a work done by Yu Chen - he have continued reworking UI for Tool Options panel. In the previous report he have demonstrated the improved layout for Circle Tool and now he have applied it to other tools - Rectangle, Gradient, Star, Polygon, Spline, Draw and Text. See some of them below.
Now Ivan continues the optimization work and we will try to bring you testing binary packages by the end of this week - so you will be able to test the results by yourself.
