Show HN: forma: An efficient vector-graphics renderer

Mozilla peeps, is it conceivable that this could eventually get into firefox, or is it not the right fit in some way.

There was a recent discussion about map rendering and I commented to "just convert to SVG and let the browser render it" to which someone said that's too slow, to which I said "so improve the browsers vector rendering" rather than do a high performance renderer just for map software.

Was this conversation about OsmAnd+ by chance? Because that could use something like this.

Edit: glossed over the "browser" part. My bad.

I wonder why their renderer is so slow. Organic Maps is super fast and smooth on my phone, though.

Is it rendering or the database access?

I see no slowness in OSM+ rendering on Android once the data for an area is loaded, as you pan, zoom, etc. But the pause between opening a new location and having it rendered is quite noticeable.

It was the rendering. I had read up on the related issue tickets, and the answer was that the vector rendering was both not optimized, and not cached in any way.

Just five days ago OsmAnd 4.3 for Android with new faster rendering engine that uses OpenGL was released.

No way! It is waaaay faster now. It was unbelievably unperformant before, but I just dealt with it because it was otherwise a pretty good map app, especially using OSM and no Google spyware.

I don't understand why this isn't mentioned in the README. I wonder how they compare!

In GIS, vector things are better, but the community used to use rasters
