- stretch central polygon a bit to avoid crash when clipping
https://www.openstreetmap.org/way/511767781
- rename polygons ("center" to "huge", and removing the "leeds_" prefix
from the others)
- generate a region overview from the huge map
- only import/match collision data on the huge map
a hard error when they become out-of-date going forward.
Better heuristics make some of these unnecessary. And now the the JSON
files are in this repo, updating files manually when pulling down new
OSM data becomes less tedious.
- Simple -- one OpenGL call and feeding to the awesome image crate
- Faster -- seemingly don't need the sleep() for whatever vsync problems
- Portable -- doesn't use the Linux scrot tool
- I can switch windows and wiggle the cursor with impunity while this runs
One disadvantage: screencaps in S3 are now slightly larger PNGs, because
for some reason, the image/gif feature is super slow, even in release
mode.
For now, this makes the process of screenshot diffing map changes
easier. But it also might help with producing raster tiles for Leaflet. #440
Also, had to regenerate lakeslice because of the previous change --
it had an old adaptive signal baked in.
widgetry, geom, and abstutil may wind up on crates.io in some form to
let other projects use widgetry. abstio has A/B Street-specific tricks
for reading data on native/web. Note widgetry still depends on abstio,
will figure out how to clean that up next.
I broke this in acadad8bd
We could fix this by making main async and fetching CensusAreas and
passing them into the generate function... but it doesn't seem like
we're using this any longer anyway.
result is usually a Ring. This gets lanes to render in the GeoJSON
export. #440
Ideally all Polygons would be expressed as an outer Ring and some
optional inner Rings. There are a few cases where this is hard, and we
instead just rely on the triangulation for rendering and point
containment and give up on GeoJSON export.
Not regenerating all maps yet -- zero screenshot diff, the map file does
change, but not sure how.
Originally it was split out to organize a separate volunteer mapping
effort, but that never took off, and it's unlikely to happen. When we
have to occasionally update the prebaked signal data for some
intersections, it's unnecessary friction to update the other repo.
later overriding a .osm file with tags for these roads. This is a way to
test the effects of making simple OSM changes locally before
upstreaming.
Also handle repeated merging collapsing one of the roads. Not 100% what
happens here, but skipping the collapsed road works fine. The scary
Montlake intersections now look great with all the merging done, so
upstreaming the change! #114
If an intersection is short, and bike is spawned, another bike coming along will attempt to fit if force_entry is true. This results in a panic. To address this, if the reserved_length is >= the geom_len, false will be returned, even if forced_entry is true.
everything along Aurora looks fine, but maybe I wrote the other way when
testing in Montlake earlier. Guess I'll find out soon. #114
Not regenerating all maps yet, since more churn is on the way.
Previously, dual carriageways (pairs of one-way roads in opposite
directions) mostly didn't get any signal templates successfully applied.
This change ignores outbound-only roads when applying the templates. In
one fell swoop, lots of previously broken signals along places like
Aurora Ave suddenly work reasonably.
generated incorrectly, but regardless, calling them TurnType::Left is
just confusing.
For the moment, always filter out U-turns from merged intersections.
When connections across merged one-ways are handled properly, we won't
need this, but in the meantime, it moves forward. #114
Not regenerating just yet, but will bundle it with the next commit.
in the interior of a big intersection. #255, #114
- No sidewalks or parking on it
- Automatically try to merge it
Bring in fresh Seattle OSM with a few places on Aurora tagged, for
further experimentation.
Also, there's some bug in the importer; Seattle maps didn't get
regenerated last change. Picking up the diffs now.
