Port camera markers, coverage, media planes, volumes and calibration to the
Navara renderer. Preserve shared source/media policy and add exact plane
picking, owned resource cleanup and idle hold handling.
Validate paired keyless dev/preview media and physical drags, native legacy,
engine contracts and full CPU/build gates. Record remaining shell, viewshed
browser and W2 performance gates; defer Dioxus and plan the transit port.
Keep shared CCTV logic independent of Cesium, release the original renderer's resources, and guard retired initialization/media work. Preserve native marker, plane, volume, calibration and input behavior.
Record keyless dev/preview validation and retain unresolved shell idle/terrain and photoreal acceptance gaps. Routine QA builds use empty Google and Cesium credentials and block paid maps before navigation.
Move native gizmo entities and input into an owned renderer. Restore the
captured camera-input flag, handle cancellation and duplicate presses, and
reject foreign handle identities. Preserve native geometry and picking.
Avoid no-op sync-chip mutations and let unchanged CCTV polls complete
without publishing scene changes. Keep health/UI polling and real geometry,
auto-hop and media updates. Extend browser idle samples across two polls.
Validated full Node24 unit/allocation, boundaries, scoped format, production,
panel and QA builds; native legacy parity, real media/GPU picks on dev and
preview, engine contracts and production shell. Retain failed evidence.
Separate native scene ownership from shared ALPR source and selection state,
and add bounded Navara sprites with the existing direction/card overlay.
Preserve marker artwork, picking, floor retries and source attribution.
Fix lost post-render wakeups and redundant mobile rail mutations, and keep
HUD typewriter dimensions stable so static views settle without extra frames.
Add parser-fed dev/preview and legacy evidence, including retained failures.
Common W2 terrain and combined performance gates remain open.
Preserve native clustering, selection and direct-action playback through renderer ports. Record both-engine dev/preview, legacy, contract, shell and build evidence with remaining W2 limits.
Keep fire normalization, LOD, anchors, cards and selection portable while the native renderer owns ground cells, sprites, input and scene disposal. Cancel superseded/removed settle timers and unregister the original sprite collection.
Preserve all ten native raster pairs exactly in dev and preview; record source/click/focus/lifecycle, legacy Metal and full regression evidence with strict comparator sensitivity checks.
Match native ground footprints, encoded alpha and source ordering on real terrain and photoreal tiles while excluding forward meshes. Cache static screen data and reduce large-disc edge work without changing GPU pixels.
Add deterministic lifecycle, source/share, foreground/horizon and three-context performance proof; restore credits for available Navara feeds and retain failure history in migration evidence.
Keep refresh, cancellation and label policy engine-neutral; inject the original native entities at composition. Prove static geometry, analyst records, owner disposal and last-good refresh behavior. Native dev and QA-preview pass 18 checks each; all eight baseline PNGs remain byte-identical.
Render satellite fleets and selected targets through mover banks and orbit lines.
Enable the celestial HUD on Navara and keep native follow explicitly in ENU.
Add deterministic interaction, share, orbit, motion and cleanup acceptance QA.
Record complete targeted acceptance and remaining shared cross-shell tile failures.
Move native points, synchronous orbit primitives, tracked entities, follow and picking into the Cesium renderer. Use appClock for satellite physical epochs and isolate the unchanged CelestialRing ephemeris. Synthetic core/dense and ISS/MEO/GEO snapshots match the baseline exactly; all gates pass. The pointer-ownership source assertion follows scene.pick into render/cesium.js; registry and import-boundary assertions now reflect the migrated satellite layer.
render/navara.js: one always-on-top engine.movers chevron bank (atlas of
every chevron icon at 32 px), MMSI pick ids, trail on engine.lines,
camera reads through the shared Navara layer view (extracted from the
aircraft renderer to src/layers/shared/render/navaraView.js, + camera
pickEllipsoid and canvas clientWidth). Registered in navaraMode.
QA: vessel qaDrawn; probe selected() falls back to getSelectedInfo;
qa-w1-layers vessel section; qa-vessels-engines side by side; --engine
for qa-vessel-cards/datum; qa-flights-engines military near pose 100 km.
Unit tests on the fake engine pass; browser runs NOT done (see progress).
src/layers/vessels/render/cesium.js holds the Cesium objects the layer
built itself, one for one: the translucent BillboardCollection of
chevrons (centred, screen-aligned, never depth-tested), the horizon
occluder, window projection, canvas size, viewer.trackedEntityChanged,
and the trail (data/trailRenderer's entity polyline, kept on Cesium: the
engine.lines Primitive path did not draw below the photoreal mesh in
round 6 — the plan's T13/T15 blocker; flights does the same).
The logic imports no Cesium: geo math, Rgba WHITE, the chevron artwork in
icons.js, clicks through the engine's selection dispatcher (own-rule
owner, same rule). Registered as CESIUM_LAYER_RENDERERS['ais-live-vessels'];
src/layers/vessels joins the boundary rule.
W1 replay vs 7c7422e2: vessels/flights/military/localAdsb counts, known
objects, screen points, requests and shot sha256 identical.
qa-vessel-cards --data synthetic 2/2 and qa-vessel-datum (?qaFeed=
vessels:fixture) 4/4, the same as 6eec8f6c.
Tests moved with the code (same meaning): cameraHandoff (the click body
is handleClick), inputOwnership (the guard precedes the click rule's
read of the pick), renderers.test (vessels in the extracted list),
importDirections (an unmoved example layer is satellites), the
ownership services fixture (renderer service).
Task 12b. src/layers/localAdsb/render/navara.js implements the Local
ADS-B renderer interface of 12a on Navara:
- markers: the shared aircraft renderer's glyph sets in magenta #ff4fd8
(class silhouette and scale, ×3 near / ×0.5 far, always on top), drawn
under every sprite layer as Cesium draws the entities; each frame writes
what Cesium's CallbackProperties gave (position, screen rotation,
visibility) and the 2,000 km display distance;
- the 978 MHz UAT ring: its own sprite set, a white ring atlas tinted
#ffb3ef, Cesium's 24 px point plus its 1.5 px outline (27 px), the same
distance scale and distance, pickable as its aircraft;
- models (the Flights GLBs, magenta MIX tint), trail and head: the shared
aircraft renderer's; the camera never follows a local aircraft.
Registered by registerNavaraLayerRenderers (import()); the Navara catalog
now offers flights, military and local ADS-B.
- ?qaFeed=local-adsb:fixture: the local receivers' answer in the server's
format (src/bench/w1Feeds syntheticLocalReceivers: 40 aircraft near JFK,
10 on 978 MHz UAT) through the layer's own decoder-feed session
(sources.localAdsbFeeds, null by default: the layer makes its own).
- qa-w1-layers --layer=local-adsb: a click selects a marker and shows its
card with the receiver line, the camera does not follow, Escape leaves
the selection (it never answered Escape), empty map releases it.
qa-w1-layers local-adsb: Cesium 12/12, Navara 13/13, --compare parity
(global pose: the 2.27 px camera offset only). qa-flights-engines
--layer=local-adsb: 14/14 (fills exact; UAT rings side by side in
docs/migration/phase3/localAdsb).
Task 12a. The Local ADS-B logic (index.js, models.js) no longer imports
Cesium. src/layers/localAdsb/render/cesium.js holds what it built, one
for one: the CustomDataSource of marker entities (billboard with
per-frame position/rotation/visibility CallbackProperties, the 2,000 km
DistanceDisplayCondition, the 978 MHz UAT ring as a PointGraphics), the
model PrimitiveCollection (models load, pose and leave through the shared
aircraft renderer's model part, adopting that collection), the selected
aircraft's trail (data/trailRenderer, as before) and live head segment,
and the camera reads. Registered for 'local-adsb' in the renderer
registry, created at init(viewer, {engine}).
- Clicks go through the engine's selection dispatcher (drill 8) instead of
the layer's ScreenSpaceEventHandler, with the layer's own rule kept as is
— a new `lookUnder` owner kind: its marker on top, or under picks no
layer owns and under trail lines, is selected (and re-selected);
another layer's contact on top, or empty map, releases only its own
selection; a trail line alone does nothing; no gesture rule. To the
other owners it is another layer, as its pick-owner registration made
it before. (The dispatcher's `drillThrough` would have taken the marker
from under another layer's contact, which the old handler never did.)
- models.js reads the camera through the renderer's view (frustum and
horizon tests, ground snap owner) and draws through renderer.models
(loadFleet/add/remove/destroy/setPose: the same MIX-tinted glTF options,
the same HPR frame with the Flights nose offset). The shared aircraft
renderer gains a loadModel seam (default Cesium.Model.fromGltfAsync).
- Cesium math → src/geo; the model tint is an Rgba equal to the old
Cesium.Color; check-import-directions: src/layers/localAdsb/ joins the
rendered layers.
Tests moved with the code, same meaning:
- index.test: the services fixture creates the layer's Cesium renderer and
the selection dispatcher; the click harness scripts the picks on a fake
engine registered for the fake viewer (was a fake ScreenSpaceEventHandler)
and the app's pick owners (trails, a Flights contact) are registered in
the pick registry (was an injected picking service).
- cockpitModels.test: the GLB loads are the aircraft renderer's loadModel
calls (Cesium.Model.fromGltfAsync by default), each asynchronous:false.
- trackingClickGesture.test: the dispatcher's empty click goes to the
plain owners (filter(plain)).
- renderers.test: local-adsb has an extracted Cesium renderer.
New: the dispatcher's look-under rule beside a plain owner (7 click cases).
W1 replay (flights, military, localAdsb) vs a fresh 7c7422e2 run: counts,
known objects, screen points, tracking poses, requests and every shot's
sha256 identical.
Task 11b. src/layers/military/render/navara.js: the shared Navara aircraft
renderer with the military's sprite slot (SPRITE_LAYER_ORDER 'military',
under flights) and jet.glb's nose offset; registered by
registerNavaraLayerRenderers (now a table of lazily imported factories,
flights and military), so the Navara catalog offers military and the main
chunk stays without three/Navara.
- The follow passes between aircraft layers on Navara as on Cesium: the
follow-handle → tracked-handle map and the "follow being started" handle
are shared by every aircraft renderer of the page, so a layer whose follow
another layer took reads the new owner's tracked handle (and its
gevSelectionOrigin) — before, it read a bare follow handle and reported
'programmatic'.
- trackById on a selected-but-not-followed contact follows it again (as
flights since 10b; on Navara any camera command ends a follow).
- qaDrawn (the probe's drawn()) for military, shared with flights
(src/layers/aircraft/qaDrawn.js).
- ?qaFeed=military:synthetic[:count]: seeded readsb rows (1 000 by
default, 150 near JFK, 12 on the ground, 8 types), the first 25 hexes
shared with the synthetic civil flights.
- qa-w1-layers: sections 4–6 read the --layer's module (were 'flights');
section 5 keeps the queries beside the voice answers (the voice block
overwrote them, so --compare never compared queries); for military: the
follow passes military → flights → military, and flights leaves the 25
shared aircraft to military while it is on (9 975 / 10 000 / 9 975).
qa-w1-layers --layer=military: Cesium 25/25, Navara 26/26, --compare parity
(queries included; the known 2.3 px camera offset at the global pose only).
Task 11a. The military flights logic no longer imports Cesium: it draws
through the shared aircraft renderer (src/layers/aircraft/render/cesium.js)
with the military's parameters in src/layers/military/render/cesium.js
(sprite-order slot 'military', jet.glb's 180° nose offset), registered for
'cesium' in the renderer registry and created at init(viewer, {engine}).
The same pure move as flights in 10a:
- Fleet: the BillboardCollection and its sprite-order slot (enable keeps
restoreSpriteOrder, as before); sprites stay Billboard handles.
- Models: fleet/tracked/preload glTF loads (asynchronous:false, MIX tint at
MODEL_COLOR_BLEND_AMOUNT, IR boost as `unlit` → the UNLIT CustomShader),
the model collection, setPose. The per-class specs keep their own nose
offset: setPose takes an optional offsetDeg (default the layer's), on
both aircraft renderers (same arithmetic, test added).
- Tracked: the ENU billboard Entity with its position/colour/rotation
callbacks (#FFD166, transparent amber once the model owns the visual),
viewFrom, followed through viewer.trackedEntity + the one exact tracked
frame; refocusTrackedById through follow.refocus.
- Trail: the entity trail and the floored live head segment.
- View: camera/scene reads, frame number, frustum and horizon tests,
render requests, frame events.
- Clicks and Escape go through the engine's selection dispatcher (the
ScreenSpaceEventHandler and keydown listener are gone); the cross-layer
untrack watches the renderer's follow. Same rules: cockpit clicks are
inert, the tracked visual/model is a no-op, another layer's pick is not
empty space, an unowned pick is.
- Colours are engine-neutral Rgba (MIL_ICON_COLOR #FFB800,
TRACKED_ICON_COLOR #FFD166, AMBER_TRANSPARENT), NearFarScalar →
nearFarScale; Cesium math → src/geo.
- check-import-directions: src/layers/military/ joins the rendered layers
(cesium only in render/cesium*.js).
- The military registry and the flights' duplicate suppression are
untouched.
Source-text tests updated with the moved code, same meaning:
- militaryAwareness.test: military's hasContact guard reads fleet.visible().
- trackingClickGesture.test: the military gesture rules are the
dispatcher's (selection gesture before select, click classifier before
the empty-space clear), military answers the empty click with a
user-origin clear — the same assertion flights already had.
- ownership.test: the services fixture names selection and renderer; the
app-composed services build the layer's Cesium renderer.
- renderers.test: flights and military have extracted Cesium renderers.
New tests: the military logic over a plain-data renderer and a fake engine
(amber fleet, click-select, #FFD166 tracked glyph, no-op on the tracked
visual, empty-click and Escape release, the keyboard left on destroy); the
plain-data renderer moved to src/testSupport for both aircraft layers;
setPose with a per-model offset.
W1 replay vs 7c7422e2 (the 10a reference run): every layer's counts, known
objects, screen points, tracking pose after 2 s, requests and the
city/global/orbit shots (sha256) identical. qa-military-names (it checks
the installations layer): the same verdict as 7c7422e2 (the zoom-markers
assertion fails on both). Main chunk 2,890,763 B (−2.9 KB).
Task 10b. src/layers/aircraft/render/navara.js implements the aircraft
renderer contract on the engine contract alone (no three, no Cesium):
- Fleet glyphs: banks of engine.movers sprite sets (one per distance scale
and depth mode the handles ask for; flights: one, 'always', Cesium's
NearFarScalar), growing by doubling, from a glyph atlas of every
aircraftIcon() kind at the fleet (64 px) and tracked (192 px) rasters
(data/aircraftIcons: AIRCRAFT_ICON_KINDS, aircraftIconCells,
aircraftIconAtlasLayout, drawAircraftIconAtlas). Sprite handles keep the
Billboard field vocabulary as setters; a frame's writes commit once at
the end of the frame listener that made them (a microtask outside one).
- Models: banks of model mover sets per glTF and look; handles report
ready from MoverSet.ready() and computedScale from minimumPixelSize kept
on the CPU (radiusM in the spec, the class's nativeRadiusM); poses are
Cesium's HPR frame (modelMatrix) turned by Navara's glTF axes
(Z_UP_TO_X_UP: its loader is already Z-up; chosen side by side with
Cesium among six candidates).
- Tracked glyph: a sprite whose position/colour/rotation callbacks are read
every frame in preRender; follow = engine.camera.follow with the tracked
readout's card as its label (gevFollowHandle); current() maps the follow
back to the tracked handle, also while follow() raises followChanged.
- Trail and live head: engine.lines (alpha 0.85, depth-fail 0.4, geodesic)
in the gev-trail pick namespace.
- View: camera/scene adapters over engine.camera.pose() (registered with
the engine so shared helpers project through it), frustum and horizon
tests, frame number, engine frame events.
flights/render/navara.js registers it for 'navara' from the Navara mode's
import(); the Navara catalog now offers Live Flights.
Also: tracking a contact that is selected but no longer followed follows it
again (a camera command ends a Navara follow; on Cesium a search flight
releases trackedEntity): trackById/select re-follows instead of only
re-publishing. Behaviour change on Cesium only in that case.
Tests: the renderer on the fake engine (contract, atlas, banks, per-frame
commits, growth, tracked callbacks, follow label, model pose, trails) and
the flights logic over it (fleet, click-select, follow, re-follow after a
camera command, release, no set left behind).
Task 10a. The flights logic no longer imports Cesium: every Cesium object it
built moved one for one into the shared aircraft renderer
(src/layers/aircraft/render/cesium.js; contract in render/contract.js), with
the flights' parameters in src/layers/flights/render/cesium.js, registered
for 'cesium' in the renderer registry and created at init(viewer, {engine}).
- Fleet: BillboardCollection + sprite-order slot; sprites stay Billboard
handles (field vocabulary documented for the Navara renderer).
- Models: fleet/tracked/preload glTF loads (asynchronous:false, MIX tint, IR
boost as `unlit` → the UNLIT CustomShader), the model collection, setPose
(same HPR frame with airplane.glb's 180° offset).
- Tracked: the ENU billboard Entity with its position/colour/rotation
callbacks, viewFrom, followed through viewer.trackedEntity + the one exact
tracked frame (kept as is; engine.camera.follow on Cesium would also end
the follow on any camera command, a behaviour change).
- Trail: the entity trail (data/trailRenderer, unchanged: its Primitive
predecessor failed below the mesh) and the live head segment.
- View: camera/scene reads, frame number, frustum and horizon tests,
projection, render requests, frame events, evidence render-loop hold.
- Clicks and Escape go through the engine's selection dispatcher (the
ScreenSpaceEventHandler and keydown listener are gone); the cross-layer
untrack watches the renderer's follow.
- Colours are engine-neutral Rgba (src/layers/shared/color.js), bit-equal to
the Cesium.Color constants they replace; NearFarScalar → nearFarScale.
- Cesium math in the logic → src/geo.
- check-import-directions: cesium only in render/cesium*.js and three/Navara
only in render/navara*.js for flights, aircraft and shared; a layer's
Navara renderer only through navaraMode's import().
Source-text tests updated with the moved code, same meaning:
- readLayerSource reads a layer's render/*.js and, for the aircraft layers,
aircraft/render/*.js (GLB-load, tracked-entity, CallbackProperty checks).
- modelScale.test: _normalBillboardScaleByDistance reads nearFarScale(...).
- spriteOrder.test: flights' enable calls fleet.restoreOrderOnEnable(); the
renderer wires it to restoreSpriteOrderOnEnable('flights', viewer).
- trackingClickGesture.test: the flights gesture rules are the dispatcher's
(selection gesture before select, click classifier before the empty-space
clear); flights answers the empty click with a user-origin clear.
- militaryAwareness.test: flights' hasContact guard reads fleet.visible().
- ownership.test: the services fixture names selection and renderer.
New tests: color, the Cesium aircraft renderer (contract, collections, pose,
loads, frustum/horizon, tracked entity, follow, trail head, adopted
collections), the flights logic over a plain-data renderer and a fake engine
(fleet, click-select, no-op on the tracked visual, empty-click release), the
boundary rule.
W1 replay vs 7c7422e2: counts, known objects, screen points (0 px), tracking
poses (0 m), requests and shots (same sha256) identical. Main chunk
2,890,982 B (+6.2 KB, +0.21 %: the renderer indirection).
The voice runner drives the globe engine (an `engine` option, by default
the one registered for the viewer) instead of the Cesium viewer:
track_entity, stop_tracking (camera.following().stop()), frame_overhead
(camera.flyToSphere with the pose heading), fly_to_location, zoom_to_globe
(follow released through camera.following()), adjust_camera_zoom,
next_iss_pass / next_satellite_pass, select_nearest_aircraft and the
analyst view context, get_current_view_state, get_entity_context
(projector.worldToWindow), the view target (picker.pickPosition, then
camera.pickEllipsoid, then picker.pickGlobe) and its moveEnd prewarm, and
the viewport samples. getBasemapLabelContext takes the engine or a viewer
with a registered engine (the HUD).
Without a viewer the tools that still need one (VIEWER_ONLY_ACTIONS:
control_scene, annotate_map, clear_annotations, fly_route, move_camera,
control_cockpit, set_context_mode, control_radio, control_cctv) answer a
structured refusal (code UNAVAILABLE_ON_ENGINE) instead of throwing.
Point-and-ask picks with engine.picker and keys the camera pose from
engine.camera.pose(); the viewport capture reads engine.host.canvas and
waits for the engine's postRender (both engines keep their drawing
buffer: Cesium's contextOptions, Navara's own WebGL2 canvas, S4).
Tests: gevActionsEngine.test.mjs runs each moved action on the fake
engine. gevActions.test.mjs keeps its expectations; its runner helper now
registers an engine for the test viewer (the Cesium engine over it, or a
fake engine at its positionCartographic) and the two harness cameras gain
roll and frustum for camera.pose().
- src/app/layers/renderers.js: the layer renderer registry
(registerLayerRenderers(engineKind, { [layerId]: factory }),
rendererFor(layerId, engine), layerAvailableOn(layerId, engineKind)).
Every application layer is registered for Cesium as CESIUM_BUILTIN (it
still draws itself until its render/cesium.js); Navara factories come with
the layer tasks. On it, the stable availability API phase 4 injects into
its layer list: createLayerAvailability(engineKind) →
{ engine, isAvailable(id), available(), unavailable() } with { id, name }
rows (src/app/layers/directory.js holds the ids and names in catalog
order; a test keeps it equal to the constructed catalog).
- createApplicationCatalog({ engineKind, availability }) constructs only the
layers the engine can show, in the same order (shared instances made
once, on demand); the catalog carries `availability` and the others'
metadata (`unavailableMetadata`). Cesium builds the same 30 layers in the
same order as before; Navara builds none yet (no Navara renderers) - the
standalone app now asks the catalog for it instead of making an empty one.
- catalogControlServices: a role whose layer the engine leaves out gets an
empty stand-in (absentLayerControlServices folded in); any other missing
layer is still a wiring error.
- LayerLifecycle(viewer, { engine }): every module call (init, enable,
update, disable, destroy) gets { signal, engine } as its second argument;
viewer is null on Navara.
- Links: a link that turns on layers this engine leaves out keeps them in
the durable state (re-saved links carry them; back on Cesium they turn
on) and activates nothing; a notice names them ("NOT ON THIS ENGINE · Kept
in the link: …"). The Navara notice lists the engine's data layers from
the registry.
- The dev launcher's CCTV wiring check matches the new catalog form.
The world overlay host already projects through engine.projector and tests
the horizon with projector.horizonVisible; the last Cesium value on its
path, the snapshot of an entry's cullPosition, is now a geo Cartesian3.
Navara's horizonVisible is Cesium's EllipsoidalOccluder.isPointVisible:
tested against Cesium's own on 8 000 eye/point pairs (600 m to 20 000 km,
points under, on and over the ellipsoid; no disagreement) and at the limb
(a label 40 m under the ellipsoid just past the horizon is hidden, with its
cullPosition lifted 100 m it is shown). It ran per label per frame with
three new vectors each call; it now uses scratch vectors. Micro-measure
(500 labels per frame, no scavenge during the run): 7 941 B per frame
before, 51 after.
The W1 sources that projected with Cesium's SceneTransforms themselves -
the icon orientation's exact projection and the launch replay overlay - go
through the engine's projector when their scene or viewer has a registered
engine. Satellites, vessel labels and aircraft recession project nothing
themselves (the host does).
scripts/qa-overlay-engines.mjs publishes the same labels on both engines at
a city, an orbital and a limb pose and compares the painted rectangles:
worst 0 / 2 / 0 px; on both, the far-side label is not painted, the lifted
limb label is and the buried one is not.
Review of Task 5: while following on Navara a left drag panned the globe
about the ground point under the cursor (range 2,154 m → 54,136 m) and the
wheel zoomed toward that point (462 m after 40 notches, Cesium stops at
the 150 m floor). While a follow runs, Navara's spin, zoom and tilt are
now suspended (input.suspendCameraInputs, which gives the app's own
setCameraInputs choice back after the release) and followGestures.js turns
a drag into heading and pitch of the ENU offset (a canvas width is one
turn, its height half a turn; elevation kept within 2°-89°) and a wheel
notch into 20 % of its range, never inside the minimum range, as Cesium's
EntityView orbits the target. The offset is no longer read back from a
camera the follow alone moves.
Also (review item 7): a follow requests a render only when the target, the
offset or a gesture changed, so a still target lets Navara idle.
The contract follow check drags (range within ±5 %, target within 3 px)
and turns the wheel 40 notches (never below 149 m, ends within 5 % of
150 m) on both engines with real input (qa-globe-contract's pointer gains
drag and wheel); after stop it waits for Cesium's gesture inertia to end
before checking that the camera is free. Contract: Cesium 73/73, Navara
79/79.
engine.surface.sampleHeightDetailed(place, { exclude, lod }) answers
{ height, source: 'tiles' | 'terrain', tileSizeM? } (src/globe/surfaceDetail.js).
On Navara tileSizeM is the extent of the tile that answered and
lod 'finest' takes the finest loaded tile, drawn or not; Cesium answers
tiles without a size, else the globe's terrain. acceptedSurfaceHeight()
turns an answer into a height or a miss: tiles larger than
MAX_FLOOR_TILE_SIZE_M (4 km) are too coarse, terrain is not the mesh.
The mesh floor sampler and the ground snap are engine-only now (a viewer
or scene reaches its engine through engineFromViewer, which also registers
the scene) and treat a coarse answer as a miss, as they treat undefined.
Measured on Navara at Austin: while the tiles stream, a 27.9 km tile reads
143.2 m where the ground is 122.5 m (a 1.8 km tile).
`exclude` takes the engine's own mover sets (MoverSet.id): Cesium hides a
set's primitive for the synchronous sample (Cesium matches excluded objects
per billboard, not per collection); Navara's ray only meets tiles.
"sampleHeight undefined in the app on Navara" did not reproduce: the
startup Austin sample is 121.9 m (tile 889 m) on Navara and 122.4 m on
Cesium; one ModelMesh class is patched.
S2 QA (scripts/qa-surface-heights.mjs, 20 places at JFK, SFO, AUS, roofs
and streets): Navara within 2 m of Cesium at 19/20 from 800 m and 18/20
from 15 km with lod 'finest' (gates 18 and 15); offsets per region
-0.21 / +0.4 / +0.1 m; the Empire State roof differs by 39 m (spire
geometry). Navara tile sizes at 800 m: 112-314 m.
camera.follow({ position, viewFrom, minRange = 150, native? }) keeps a
moving target centred at an east-north-up offset the user may turn and
zoom; camera.following() and camera.followChanged report it; stop() frees
the camera and a camera command (setView, flyTo, flyToSphere, lookAt,
cancelFlight) ends it.
Probe ruling: Navara 0.2.1's cameraFollow holds the target but ignores the
user's drag and wheel, the aircraft sits ~13 px off centre with 7.6 px of
spread, and calling it without an offset each frame gives a NaN camera.
So Navara (and the fake engine) follow with src/globe/follow.js: each
frame, before Navara draws, the offset is re-read from where the user put
the camera relative to the previous target, kept outside the minimum
range and carried to the new target.
Cesium follows with viewer.trackedEntity: the layer's own Entity
(`native`) or a proxy Entity at position() with a 1 px transparent point,
since EntityView moves the camera only for an entity with a bounding
sphere. applyTrackedCameraFrame and the zoom limits moved to
src/globe/cesium/follow.js; src/data/trackedCamera.js keeps the pure parts
(the range clamp now lives in src/globe/follow.js). following() also
reports an entity the app tracked itself. Camera sensitivity claims made
on a viewer's Cesium camera now share the engine camera's ledger, and the
orientation controls and the world jump read the follow from the engine.
Contract (both engines): a target flying at 250 m/s stays within 3 px of
the centre for 2 s, zoomIn through it stops at 150 m, stop() and setView
end the follow. Cesium 71/71, Navara 77/77; shell 23/25/4.
check:boundaries failed from 76851ee9 on: vite-build did not own the
initial-chunk guard, and the layer and application packages did not own
src/time/clock.js and the movers, lines, picks and Navara overlay modules
they now reach.
- The takram uniform paths move to internals.js (forEachLuminanceUniform,
loud in dev when a path is gone); look.js sets each factor to scale x
the recorded base value, so shared or copied vectors are never scaled
twice, and the stars keep the base value (own vector when shared).
Stars at intensity 120: a starfield shows from space.
- Both night-side shader variants compile on the first two frames.
- The clouds hide once the sun sets at the camera (dark puffs at dusk).
- No allocation on look frames that change nothing (frozen updates, a
scratch camera place from livePosition).
Gallery regenerated.
The atmosphere draws physical radiance scaled for an exposure near 10,
while the baked Google tiles need exposure 1, so the noon sky came out
dark navy with the stars showing through. The cinematic look now scales
the atmosphere's radiance-to-luminance factors (sky, aerial perspective,
clouds) by 3, leaving the tiles alone, and shows its stars only from
space or with the sun below -6 degrees at the camera. Gallery
regenerated.
The contract gains render.setSharpen({ enabled, amount }) and
render.sharpen(). Navara draws it as a custom EffectDesc: Cesium's unsharp
mask (3x3 box blur, gamma 2.2 round trip so one amount matches Cesium)
right after tone mapping and before SMAA/FXAA, skipping sky and cloud
pixels by scene depth. The Cesium engine keeps the state only; Cesium mode
still sharpens with its own post stage, unchanged. The fake engine records
it and the contract suite checks it.
Without a viewer the Sharpen slider and toggle drive the engine with the
same slider-to-amount mapping. On Navara the defaults, presets and share
links read Cesium's 49 % as 80 %.
navaraScenePlan gains a pure `cinematic` plan, now the default of the app's
Navara mode (`?look=photoreal|minimal` picks the others): photoreal plus
volumetric clouds (low quality, layers from 1,500 m, no ground shadows),
ACES tone mapping, brighter stars and no sun shadow maps. From space, at
rest, the aerial perspective lights the globe from the atmosphere for a
real night side and terminator; it switches off below 1,000 km so the
Google tiles keep their baked light.
look.js builds the plan and keeps it current on frames Navara draws
anyway: the atmosphere's sun date follows the wall clock (the HUD's SUN
elevation), and the clouds hide above 4 km or over high ground in view,
parking their last image so the aerial perspective shows no ghosts.
Navara 0.2.1's camera controller has no terrain or tile collision; its
only zoom limit, minimumZoomDistance, is a distance from the Earth's
centre, so a wheel zoom near the ground went through it (to -5.9 km).
groundFloor.js runs on the engine's preRender after the camera model
reads Navara's camera. While the camera is free (no flight, no lookAt
target) and below 20 km it samples the ground under it (tiles, else
terrain, else the ellipsoid; at most every 250 ms or 20 m), feeds
Navara's clamp (minimumZoomDistance = geocentric radius of the ground
point + 30 m, sent on changes over 10 m, reset to Navara's default
during flights and above 20 km) so the wheel stops smoothly, and lifts a
camera still below ground + 30 m straight up without camera.commanded.
It only lifts, so it cannot oscillate with the shell's ground guard,
whose lift is a flight the floor stands aside for.
The page's engine is ?engine=cesium|navara, else localStorage gev.engine,
else Cesium (src/app/engineChoice.js). Cesium mode is unchanged.
In Navara mode (src/app/navaraMode.js, loaded with import() only then,
and loading the Navara globe the same way) the scene builds the Navara
globe on the app container with no viewer; map stacks go through
engine.maps (Google 3D from the browser key, else Esri imagery); only the
shell's own data credits are registered. The layer catalog is empty and
the controls get empty layer stand-ins. The shell does not create its
viewer-bound parts (cockpit view, celestial ring, detection, tracked
readout, post-process stages); the tools install the render governor on
the engine, skip the director, annotations, drawing, imagery box, scope
mask, voice and embedded views, skip the first-run welcome, and show
"Experimental Navara engine: layers, cockpit, director and voice are
unavailable". window.__godsEyeView.viewer is null.
Navara's attribution card is kept clear of the location tray. A few
shell paths became null-safe for the missing viewer, layers or stages
without changing Cesium behaviour.
scripts/qa-engine-shell.mjs checks both modes headless: boot, viewer,
console errors, map drawn, search and fly, north/tilt/zoom/reset, orbit,
HUD, share link restore and map stacks.
The import-direction check now tells dynamic imports apart
(analyzeModule(source, { dynamic: true })) and rejects any static import
or re-export of src/globe/navara/** from outside that directory, so the
Navara engine can only be a lazily loaded chunk of the app.
Navara's prebuilt workers load their wasm by file name next to
themselves, which the bundler cannot see; a build-only Rollup plugin
copies the missing ones (draco decoder, font worker) into assets/ when
the bundle includes Navara, and adds nothing to a build without it.
The application shell keeps the page's globe engine and hands it to the
navigation controller, location navigation (search, city and POI flights,
orbit, globe reset), the tilt and north-up controls, share-link save and
restore, share restoration's first-gesture listeners and the HUD. The
viewer is passed only where entity tracking still lives on it (phase 1c)
and to the HUD's basemap label context (voice); every such use is null-safe.
Share links and captured shots write heading and roll as Cesium's camera
reports them (src/cameraAngles.js): the contract's [0, 2π) pose maps an
exact 0 back to Cesium's 2π, except the roll of a vertical view, so
links stay byte-identical (heading=360, roll=360) on every engine.
Source-reading tests follow the moved code with the same checks.
The startup fly-in, orbit, world-target focus, the arrival ground guard,
arrival ownership, camera sensitivity claims, landmark/viewport/globe
flights and place search (with its view bias and near-view recovery) take
the globe engine. Callers that still hold a viewer (voice, layers until
phase 1c) reach the same engine through engineFromViewer, and arrival
ownership is keyed by the engine whichever one a caller names.
The ground guard yields on camera.commanded instead of patching the
viewer camera itself; on Cesium that event hooks the same command methods
and tracking changes, so direct Cesium callers still end it. Landmark
framing reads the frustum fov from the pose's fovy and aspectRatio.
Tests that built viewer doubles now run on the fake engine (or on the
Cesium engine over the same double), with the same expectations.
Map credits (maps/credits.js) are shown through a credits capability
(engine.credits.addStatic) instead of the scene's credit display; the
shared map scene takes the engine's credits, so the Cesium engine's maps
and its credits part share one owner. Data credits (registerDataCredits,
registerDynamicCredit, show/hideOsmCredit) take the globe engine and keep
accepting a viewer from layers that still hold one; the scene registers
the data credits on its engine. The Cesium credits part reads
Viewer.creditDisplay, else the scene frame state display it aliases.
The world overlay host takes its frames (frames.postRender), camera events
(camera.moveEnd), canvas size (host.size), projection matrix
(projector.viewProjection), horizon test (projector.horizonVisible) and
render requests (render.request('world-overlay')) from the globe engine.
initWorldOverlay accepts an engine or, for callers that still hold a
viewer, resolves the viewer's engine through engineFromViewer.
Contract: camera.position(result) becomes camera.livePosition, one
engine-owned object holding the current position, so per-frame readers
and paint lanes keep a live camera position without allocating; engine
events gain raiseValue for argument-list-free frame dispatch. Steady-state
frame allocation is unchanged (worker probe, 30 chunks: 2696/9536/38593
B/frame before and after; detection 473749 -> 408085).
Contract: camera.position(result?) and camera.height() for per-frame
readers, render.request(reason?), maps.releasePhotorealTiles, sources
with a caller-owned ready provider, isGlobeEngine. engine.maps now hides
every tileset it has shown, lets the last imagery/photoreal call win, and
setPhotorealTiles(null) restores the last base imagery and its credit
instead of leaving the photoreal credit on a bare globe.
Cesium engine: reads the Viewer camera/canvas aliases, detaches bridged
events through the remover Cesium returns, raises frame timestamps
without allocating, re-aims the horizon occluder only when the camera
moved, and renders the scene directly when the governor governs another
viewer (or none yet). engineFromViewer returns the registered scene
engine of a viewer, else builds and caches one. The render governor stays
the Cesium render backend under engine.render and gains
isRenderGovernorInstalled.
The scene builds the page's Cesium engine right after the viewer
(src/app/globeEngine.js), names the startup Google tileset to it once
loaded, returns it beside the viewer and destroys it before the viewer.
The debug handle exposes it as window.__godsEyeView.engine. Nothing
consumes it yet; render holds taken before the governor is installed
apply at install.
qa-globe-contract now runs on the app's engine (self-built only when the
app has none); a throwaway engine checks creation and destroy leave the
scene untouched.
Map sources are applied through one src/maps/sceneApply.js helper shared by MapSourceController and engine.maps (live layer kept for an unchanged provider, providers cached per source). The contract gains flyTo endTransform and rectangle destinations, flyToSphere easing, drillPick width/height and pick content, with Cesium's own flyToSphere range. Input skips listeners removed during dispatch and stays inert after destroy.
