The transit layer knew five modes, so a trolleybus drew as a bus, a
funicular as a train and a coach as a city bus. The GTFS basic route types
are now modes of their own (trolleybus, cable_tram, monorail, funicular,
aerial_lift), each with an icon, colour, detection tier, card word, voice
name, speed ceiling and fleet model.
A vehicle record may carry its route's GTFS route_type as routeType. It
settles the mode after the feed's fleet hint and before its route hint, and
picks the finer model (a coach for 200, a high-speed set for 101) when the
type is a kind of the vehicle's mode. Retained history classifies epochs
through transitModeFor too, so trails join the live vehicle.
Route hints from each operator's routes.txt: Prague's trolleybus lines
(51-59, 232, 275) and Petrin funicular, and the trams, trolleybuses and
metro lines of Bucharest, Cluj-Napoca and Turin. A feed may also name
route corrections that outrank the route type: Le Havre's routes.txt types
its funicular (8-FUNI) as a bus, so it is corrected to a funicular.
A virtual aid (AIS message 21's VirtualAtoN flag) is a mark broadcast
where nothing physical stands, so drawing it as a buoy showed a mark
that is not there. The vessel source record now carries `virtual`
(false unless a source says true; any source may set it), AISStream
sets it from VirtualAtoN, and the vessel layer keeps such an aid's
disc: vesselModelSpec returns null for it and the layer gathers no
model item for it. Its card, selected card and readout add VIRTUAL
after its kind.
A buoy's card, selected card and HUD readout showed "0.0KT · 135°" from
whatever its source reported. A fixed mark has neither, so they now show
its kind alone, whole ("CARDINAL MARK N", which the 14-character type cut
read as "CARDINAL MARK "), in the bone white of its disc.
isAidToNavigation now knows every kind an aid report names ("Light, with
sectors", "Fixed structure off shore" had no aid word), leaves out a
"Buoy Layer" as it does a tender, and matches each type text once: the
vessel layer asks per vessel on its rotation pass, which now skips the
aid discs it never turns.
Aid rows no longer cost ships their place: aisStreamRows lists every
vessel ahead of every aid, so the layer's 12,000-row request never drops
a ship for a buoy, and vessels_in_area (and the brief built on it)
counts ships only. An aid's name runs on into its NameExtension.
A buoy, beacon, RACON, light or IALA mark in the vessel feed was drawn
as a ship. A vessel record whose type names one, or whose MMSI is an
aid-to-navigation station's (99MIDxxxx), is now isAidToNavigation and
vesselModelSpec draws it as the fleet set's buoy of its mark (cardinal
N/E/S/W, port or starboard hand, safe water, isolated danger, special
mark; a red can when the type names no mark), at its built size and
flagged fixed so its model does not turn to a heading. Its icon is a
disc instead of a chevron.
AISStream now subscribes to AidsToNavigationReport by default, and the
server names each report's aid type code (0 to 31) as its kind instead
of reading it as a ship type.
readsb rows (adsb.lol and a local dump1090 receiver) often send no track for
an aircraft on the ground, only its true heading. The track then read as
missing and the aircraft was drawn facing north, so one taxiing south looked
like it was moving backwards. Each normalizer now falls back to true_heading,
never the magnetic heading.
Every aircraft model (Flights, Military Flights, Local ADS-B) mixed 94% of a
flat class colour over its mesh, so airliners drew as white silhouettes and
military ones as amber. Models now use HIGHLIGHT: white leaves the mesh's own
colours as built, and the tracked and emergency colours tint the mesh without
hiding its paint. The IR boost still draws them flat white.
The car, van, fire truck and pushback tug were stacked boxes. The car is now an
operations SUV (rounded body, glass house with a sloped windscreen, roof light
bar, grille and lamps), the van a high-roof panel van, the fire truck an airport
crash tender with roof and bumper turrets on three axles, and the pushback a low
chamfered tug with a glazed cab. All stand on the ground at their built size.
Their trail anchors are measured again.
Feeds carry many airport ground vehicles (type ZVEH) and ground stations
(GRND) that were drawn as the generic plane, some at the 10 km airborne
default.
- types.json gains aircraft_callsign rules: a ZVEH callsign starting FIRE is
a fire truck, PUSH/TUG a pushback tug, DEICER/SQUID/SQB a van, else a car.
GRND draws a new 11.8 m radio mast (other/radio_mast.glb).
- resolveAircraft and aircraftModelSpec take the callsign; a matched rule
names the model outright, ahead of the type's class model.
- The layer spec cache keys such types by the rule matched, so it holds at
most one entry per rule.
- These models (catalog category `other`) draw at their built size, as such
models already do, and a
contact with no altitude whose model is one now stands on the ground; the
feed's own type is kept for such contacts, as no airframe lookup knows it.
- Local ADS-B passes the callsign too.
The session snapshot recorded a user's switch only after the CCTV panel had
already rendered the layer off, so a first switch-off by the user inside
Contacts, or after a partly failed restore, still kept the panel open.
Context controls now hold the layers _clearLayersOutsideContextMode is
switching off while its transitions run; suspendsLayer reads that set, and
the snapshot is no longer consulted.
- A frame with no speedMps gets an exact anchor: an inertial one ran on at
zero speed and closed at 0.75 m/s, so the camera fell kilometres behind a
moving train. The docs example now passes speedMps and anchor: 'exact',
a name for its HUD, and isEntryAllowed for a train bound to its line.
- Transit's snapshot height is the floor where playback draws the vehicle,
not the newest report's floor uphill, and null while that floor is cold,
so a view waits for the surface instead of standing on the ellipsoid.
- Rail's direction follows playback once it has placed the train: a report
that runs back (a reversal, or GPS jitter) no longer turns the view
while the drawn train still runs forward.
- A frame's id is trimmed as the candidate's is.
- A double-click on the selected vessel no longer enters an application's
subject that took entry after it.
- The docs import from gods-eye-view/..., the package's name.
An inline panel that lost its WebGL context showed the panel runtime's own
notice and, over it, an alert dialog with no buttons that it could not act
on. With allowReload false a lost context now clears the notice and shows
none, as the docs already said. keepPanelRendering no longer logs render
errors itself: the render failure notice logs each one. Name the Cesium
private fields finishRaise and reportThrown rely on, and the version they
were checked against.
Turning a layer on does not leave Contacts, so a user could turn CCTV back
on inside the mode and off again; the layer was still in the session
snapshot and the panel stayed open on an empty frame. The snapshot now
records every layer the user switched during the session, and
suspendsLayer is true only for a layer isolation switched off that the
user has not touched since.
Contacts and Space Missions switch CCTV off to isolate themselves and restore
it on the way out: the panel and its share preference now stay as they are for
that round trip, as they do for Clear selected data layers. The controls no
longer read the collapsed class before asking: the panel chrome tells a panel
the accordion folded from one whose saved state is closed.
The camera controls gate asserts the collapse, reopens CCTV from the right
rail before switching it back on, and runs a Contacts entry and exit with the
panel open.
The panel opened itself when a camera became active, but nothing closed it
when the layer went off: it stayed expanded, empty, and its meta line still
described the last camera. The collapse runs only on the on-to-off change, so a
panel opened by hand while the layer is off stays open, and a context-mode
layer clear keeps the panel as Radio does.
Four test files built the same widget on CesiumWidget.prototype, viewer
proxy, store and notice; renderLoopFixture.mjs now does it once. The notice
test drives Cesium.Event instead of a hand-made double. frameEvents() drops
tileset.tileLoad, which Cesium raises inside its own error handling, and the
notice no longer guards a viewer without a canvas or requestRender.
The fleet models (#1714) draw nearby trains and vehicles under the 3D toggle. A
held one now leaves out its model as it does its icon, as the Vessels layer does
for its bridge subject: its model item is hidden, and handing the visual back
to its icon keeps the icon hidden while held. Tests drive each layer with the
real fleet-model layer and a stubbed glTF loader; both fail without the fix.
Most live vessel feeds send no length, and the resolver then fell through
every length rule to the range's last model drawn as built, so a cruise
ship or a container ship showed as the smallest model of its range.
types.json gives each passenger, cargo, tanker, fishing and service range
a typical_len (cargo 300 m, tanker 250 m, passenger 140 m, fishing 40 m,
...); a vessel with no usable length is chosen and drawn at it.
Comments keep only the why: the loop-running flag, the mid-raise events and
the one-time canvas focus. The CURRENT-STATE section lists behaviour and
pitfalls instead of retelling the code, and no longer says every tileset
event is raised outside Scene's error handling.
- a vehicle drawn as a model keeps its selected card and stays in the detection overlay
- transit and rail models drop the 1.5 m floor lift their icons carry
- vessel models are clipped below the waterline
- models switch to an unlit white look under NVG/FLIR and back
- unknown transit modes keep their icon
- aircraft model specs are cached per set; no key-array copies per frame
