Remaining review follow-ups for the sonar pulses.
No self-echo: pulses are born 5 km out (startFraction of the radius),
but contacts nearer than that, the subject included, still lit on every
pulse birth. They now never echo. Just past the birth ring, an echo is
scaled with the front's own fade-in, so a bracket no longer flashes
before a visible front reaches it. The ring flash at the full radius is
unchanged.
Older Safari: the reduced-motion listener falls back to the media
query's addListener / removeListener when addEventListener is missing,
as other modules here already do.
Echo wiring test: a detectionHost test now paints through the real
detection lane with an echo field set, and checks the echo stroke takes
the echo colour on the default style and each style's line colour under
CRT, NVG and FLIR. CURRENT-STATE notes the 5 km no-echo zone.
Review follow-up for the sonar pulses (the non-blocking items).
Unpickable pulses: the three pulse lines were polyline entities, which
Cesium always picks, so near-miss and touch picks around them became
unowned hits. They are now drawn by the pulse disc's shader, which
already drew the gradient and is built with allowPicking false. Each
line keeps the polyline outline material's look: 3 CSS px wide with a
1 px dark outline in the ring's colours, measured from the screen-space
gradient of the disc's radius times czm_pixelRatio, as Cesium's contour
material does. Without derivatives only the gradient band is drawn.
Disc follow: with the lines on the disc, it is rebuilt after the subject
moves 500 m instead of 2 km, so the pulses stay concentric with the
ring. A resting disc is hidden and not rebuilt; it catches up when the
pulses wake.
Camera below the disc: the disc sits 2.5 km above the ellipsoid with
faceForward, so from a lower camera it swept across the sky. It is now
hidden while the camera is below that height.
Echo palette: echo brackets keep the pulse blue on the default
detection style and take the style's line colour under NVG, FLIR and
CRT.
Echo test: the detection renderer's echo maths moves into
awarenessEchoBracket and awarenessEchoColor in src/awarenessEcho.js,
tested directly instead of running a regex slice of detection.js
through vm, and the one-sided spread assert is now two-sided.
The positions reuse parameter of awarenessRangeRingPositions and the
pulse segment count had no callers left and are removed.
Review follow-up for the sonar pulses.
Bounded repaint: the pulses used to ask for a frame every 80 ms from a
setInterval for as long as a subject was shown, so a parked view
repainted at 12.5 fps indefinitely. They now run for 9 s (three ring
flashes) after a selection or a camera move, fading in and out over
1.2 s, then rest: the ring stands on screen at full strength, the pulse
lines and gradient disc are hidden, echoes stop, and nothing asks for
frames. A moving subject does not wake them, since a flying subject
moves on every refresh. The lifecycle's existing camera pose signature
wakes them.
No beat with the Cyber sonar: the setInterval is replaced by a
postRender-armed setTimeout on CYBER_SONAR_RENDER_INTERVAL_MS, as in
cyberSonarScene. Every drawn frame, whoever asked for it, re-arms the
request 80 ms later, so requests never land inside the detection
lane's 80 ms gate.
Reduced motion mid-session: a change listener on the media query
rebuilds the visual, and the same-subject refresh path rebuilds when
the preference no longer matches. The listener is removed in
clearVisual.
Readable edge: restOpacity goes from 0 to 0.4, so the 250 km ring stays
visible between flashes, in screenshots and for low-vision viewers.
The echo field takes an optional level so echoes rest with the pulses.
CURRENT-STATE and the changelog fragment describe the bounded run and
the dimmed ring.
Tests: render requests stop after the bound and stay stopped for a
minute; a camera move seen by the lifecycle wakes them for another
bounded run; a foreign frame postpones the next request to 80 ms after
it; reduced motion flipped by event and by a later refresh; the ring
never drops below restOpacity; echoes scale with the level; the level
fades in, holds, fades out and keeps its value when woken.
Pulses: three dim rings grow from the Global Context subject to the
250 km range ring at constant speed, one every 3 s, each taking 9 s.
Each fades in over its first 8% of travel, then fades as
(1 - travel)^1.5 to about a third of its 60% peak, so it arrives at the
ring dim but visible. They are 3 px in the ring's colours, as polylines
with CallbackProperty positions and colours that share the ring's
centre object, so they follow a moving subject.
Ring: while pulses run, the 250 km ring rests unseen and flashes to full
strength as each pulse reaches it, fading over 1.8 s. Without pulses
(reduced motion, or a scene with no primitives or preRender hook) it
stays on screen as before.
Gradient: behind each pulse a radial band in the same blue fades inward
over 35% of the radius. One flat, translucent, unpickable 250 km disc
draws it with a small Fabric material. A preRender listener writes the
pulse radii and opacities into two vec4 uniforms each frame. The disc
(0.25 degree granularity, ~3.5 ms to build) is rebuilt only after the
subject moves 2 km.
Echoes: as a pulse front crosses a flight, military aircraft or AIS
vessel, the detection overlay draws a second bracket in the pulse blue
around that contact's own bracket, spreading outward as it fades over
1.4 s. Awareness publishes the field (centre, radius, pulse timing,
echo styling) through the new src/awarenessEcho.js. The overlay reads
it, so no layer's icon or colour is touched. Mapped installations have
no detection bracket, so they do not echo.
Rendering cost: pulses never hold continuous rendering. They ask for a
frame every 80 ms, the Cyber sonar's parked cadence, so a parked
Contacts view repaints at ~12.5 fps while a subject is shown. This
changes the "parked Contacts stays quiet" behaviour on purpose.
clearVisual stops the timer and removes the disc, the listener and the
echo field.
awarenessRangeRingPositions can now reuse a result array, and passes the
WGS84 ellipsoid explicitly so a reused Cartesian never lands in the
ellipsoid argument. Tuning lives in AWARENESS_RANGE_PULSE,
AWARENESS_RANGE_ECHO and AWARENESS_RANGE_RING_STYLE. src/awarenessEcho.js
is registered in the awareness-layer, application-components and
application-layer-construction packages.
Tests cover:
- the pulse curve and calm rate;
- the ring flash once per arrival, and the static ring without pulses;
- the 80 ms frame cadence and its stop;
- the partial-scene fallback;
- the gradient disc: unpickable, uniform values, rebuild and cleanup;
- per-frame evaluation, and the echo field following the subject;
- awarenessEcho strength, rim wrap, layer filter and altitude handling;
- the detection renderer's echo-bracket band and outward spread.
The Global Context range ring was a Cesium ellipse outline at 1 px in
rgba(98,181,255,0.72). WebGL ignores larger ellipse outline widths, so it
could not be thickened, and it vanished over desert and snow and under the
FLIR, NVG and CRT styles.
Draw it as a polyline instead: a 4 px line with a 2 px Context-blue core
inside a 1 px dark halo on each side (PolylineOutlineMaterialProperty).
The halo gives luminance contrast on light and dark ground, which the
monochrome styles keep. The ring sits at the same 2.5 km height and
follows the subject on the same 250 m threshold. Positions come from a
new awarenessRangeRingPositions helper that stays within 50 m of 250 km.
Style values live in AWARENESS_RANGE_RING_STYLE (awareness/policy.js).
Adds rangeRing.test.mjs (geometry at equator, Sahara, Greenland and the
antimeridian; contrast; entity shape; follow threshold) and a
CURRENT-STATE note.
A building word ending the ask ('… Chapel', '… Library', '… Hall') now
passes the last-word rule only when the result is one a building ask
would accept, so a campus, zoo or district whose name merely starts the
ask (Duke University, Old Town) no longer answers it.
- A building word ("Burj Khalifa Tower", "Sagrada Familia Church") passes
the last-word rule on a building-like result; enclosures stay out.
- The anchor chooses only among the best-named outlines, so a worse name
never wins by containment alone.
- An ask without a quadrant takes only the quadrant of the matching street
nearest the point; a leading quadrant ("SE Main St") may go unsaid too.
- On an unbuffered tile edge a fragment shows as an edge along the
boundary, so a whole building touching it at a corner is not cut.
- Drop two orphaned comments and correct the place-name key wording.
Opening Utilities while Data Layers is open no longer forgets that Contact
was folded for the first, and closing one of them leaves Contact folded
while the other is still open. Enter and Esc in a drawn shape's name keep
focus in the field instead of dropping it to the page. The draw tool's
destroy test now checks it stops following the board, and the Draw gate's
amber-count comment sits on its function again.
- One place-name key for server and tiles, so "St. Paul" and "Saint Paul"
agree in Nominatim name checks.
- Tile street names: a lone letter is a direction only beside another name
word ("E Street" is not "East Street"), and a trailing quadrant ("E St NW")
may go unsaid in the ask.
- A building cut at the tile edge that is nearer the point than any whole
one leaves the point instead of a farther neighbour standing in; an edge
without a tile buffer counts as a cut, so a cut area never answers grounds.
- A batch building install re-judges only results that installed; a late
timeout during caption conversion keeps the pending point drawn; a failed
plain recaption keeps the old mark addressable.
- An interrupted Nominatim dispatch is reclaimed by the next lock owner ten
minutes after the start its marker names; node:sqlite loads on first use
without its experimental warning.
- PHOTON_URL accepts only https, which the page's connect-src allows.
- Shared OpenFreeMap tiles decode each layer when a consumer first selects
it; outline selection reuses the shared ring area and simplification, and
ground probes the shared ring centroid; the grounds word list lives once.
main moved the panels to Vue views and a one-open-panel rail, and removed
the two templates this branch edited. This merge carries the branch onto
that architecture; it adds no behaviour of its own beyond the port.
- The Utilities panel is a RailPanel in LayerPanelsView with its own rail
item (handyman). LayerPanel renders the Directions rows into its list with
LayerRows, and falls back to Data Layers without it.
- Draw leaves DisplayPanel for DrawControls, DrawMarkList and DrawSwatches,
which render what the draw tool publishes to the display store and call
its actions, as GeoImport does. drawMarks.js words the rows; the DOM-built
drawMarkList.js is gone. A row's fly-to is an immediate navigation like
Import's ('drawing' gets its Cockpit refusal), the name field keeps a
draft through v-field-value, and the colours are one radio group with a
single tab stop.
- UiSegmented draws an option's icon, named by its label, for the shape
buttons.
- The catalogs take main's languages with this branch's strings, Arabic
included, and the tests follow the views to their new homes.
A street ribbon that holds neither its ring mean nor the anchor is centred
on the street's nearest point when the street runs within 100 m.
Nominatim outline selection ranks an exact name, then one holding every
asked word, then an overlap, and refuses an overlap whose name lacks the
ask's last word unless that word is in the result's address or type, so
"Central Park Zoo" is no longer Central Park. The server caches every
accepted outline and answers each ask with the one holding its resolved
anchor (sent as alat/alon), read across the antimeridian.
A duplicate mark that fails to clean up no longer tears down the new
outline it duplicates.
Directions, the Contacts marker and panel, placed annotation labels, the
drawn-line measure, the Cockpit and formatRouteDistance each chose the unit
and precision on their own, and most chose before rounding: #1450, #1433 and
formatDistanceText or kilometreDigits from src/data/distanceFormat.js, which
cut after rounding. Each keeps its own metre step and rendering.
That also fixes the 10 km cut the Contacts marker and panel, the drawn-line
measure and the Cockpit still had (9,960 m read 10.0 km). The helper returns
kilometres already rounded, so the plain marker and the localized panel no
longer disagree on half-tenths such as 1,450 m.
A negative annotation distance now leaves the label without a distance, and
a drawn line with a coordinate that is not a number shows no measure, rather
than printing 0 m or NaN km. The HUD altitude tag and the spoken view height
keep their own unit choice.
UiRail takes `collapsible`: while no panel on its side is open, each item
shows its icon and label as a pill, and once one opens the labels fold away
to the icon rail, making room for the panel. The tip is not shown while the
label is on screen; the button keeps its accessible name and the visible
label is hidden from assistive technology. The side panel rails turn it on.
Each rail is now placed by its screen-side edge, at the rail clearance, so a
rail that widens grows toward the middle of the screen; collapsed, it sits
6px outside its stack as before.
The transit, ALPR, vessel, CCTV and flight/military context fixes each
wrapped 359.5° to north with an inline Math.round(x) % 360. They now call
roundHeadingDegrees in src/data/headingDegrees.js, which also wraps negative
and multi-turn bearings. normalizeHeading moves there with it, and
cockpitMath re-exports it so existing imports keep working. It now adds a
turn only to a negative remainder, so a bearing just under half a degree
keeps its precision.
The awareness, Local ADS-B, cockpit wind, cockpit heading and Street Level
readouts use the same helper. The Cockpit's TRACK ACQUIRED signal rounded
without wrapping and could read COURSE 360°; it now uses
formatHeadingReadout, which shows --- for a track that is not finite.
