Review of Task 4: the CPU picks (Navara hover, drill, the stale-answer
check) took a sprite or point at its full sizePx however far it was, so a
set shrunk with scaleByDistance was picked well off its drawn edge. The
radius now scales by the set's scaleByDistance at the instance's camera
distance, linear between near and far as the Navara shader draws it.
Review of Task 4:
- a Cesium pick whose top result is filtered (a pickable: false set, the
follow camera's proxy entity) took nothing; it now drills and answers the
first result under it with an id (an object), else the first kept one
(map tiles);
- billboards and points drawn without a depth test reach Cesium's GPU pick
through the globe: mover instances behind the horizon (projector
horizonVisible on the instance position) are left out of picks and
drills, as Navara's CPU drill already did;
- the follow proxy entity (1 px point, cesium/follow.js) carries
gevFollowProxy and is never a pick (review item 6).
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.
Review of Tasks 4-5: the overlay pass encodes linear to sRGB, and the
instance and line colours went in as if linear: grey 0.5 drew 187 (Cesium
128) and [1, 0.6, 0.2] drew 255/203/124 (Cesium 255/153/52). The sprite,
point and line shaders now decode them (sRGBTransferEOTF), as the sRGB
atlas texture already was.
A contract check draws mid-tone sprites, points and lines (grey 0.5 and
[1, 0.6, 0.2]) and reads their centres: within 3 per channel on every
engine. 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.
Review of Tasks 2–3:
- the mover store's instance checks no longer build arrays or closures
per set() (orientation and colour checked field by field), and dirty()
returns one reused range object;
- Cesium models get their matrix and colour through scratch objects
(Model.modelMatrix and Model.color copy what they are given) instead
of a new Matrix4 and Color per placement;
- a destroyed MoverSet releases its store (count 0, empty instance
arrays, no pick ids) so a set object a layer still holds keeps no
memory, and the Cesium parts drop their billboard, point and model
lists;
- (with the overlay commit) the Navara line viewport is updated in
place.
Node micro-measure, 10 000 instances set + packed per frame: 0.27-0.29
ms, about 1.7 KB per frame (0.17 B per instance), as before. Contract:
Cesium 70/70, Navara 76/76.
Review of Task 0:
- build/navaraDependencies.js reads the dependency closure of
@navaramap/three and @navaramap/three-default-plugin from node_modules
(dependencies and peers) and drops what the app's other bundled
dependencies reach too (Cesium is served as a script, so draco3d, which
only Cesium shares, stays engine-only), plus three and postprocessing:
88 packages today (the @navaramap/* packages, @takram/*, @react-three/
fiber, @sparkjsdev/spark, astronomy-engine, d3*, draco3d, n8ao,
three-stdlib, …). The browser build's initialChunkGuard fails on a
module from any of them in an initial chunk. Tested on a fixture tree.
- check-main-chunk's budget measures the entry the page loads (the same
chunk the composition check reads), falling back to phase 4's largest
index-*.js only for a dist without a page.
Build clean: no Navara-only module in the initial chunks; main chunk
2,869,565 bytes (gzip 889,041).
Review of Task 0: the recorded live feeds left vessels (no AIS key here)
and local ADS-B (no receiver) empty, and flights held one adsb.lol
viewport answer. src/tooling/w1Feeds.js builds seeded answers relative to
one frozen instant (2026-10-16T12:00Z): a global /api/flights OpenSky
snapshot (8 000 aircraft, 2 000 within 60 km of JFK), /api/vessels with
12 000 AIS rows worldwide and the rows within the city area (the area
answer first, the global one last as the replay's fallback), and
/api/local-receivers/aircraft with 40 aircraft near JFK on 1090 MHz and
978 MHz UAT. Tests read them back through the app's own parsers.
qa-w1-baseline --synthesize=DIR writes them beside the recorded
military, satellites and launches; a replay now logs every feed request
and how it was answered (exact / as another key / none) into
summary.json, and --compare diffs those too.
Replayed on d50eaa28 and HEAD: flights 8 000, military 154, local ADS-B
40, vessels 12 000, satellites 824, launches 24; the runs agree (counts,
known objects, screen points, tracking poses, requests). The Cesium
reference is re-recorded this way before Tasks 10a, 12a and 13a.
Review of Tasks 2 and 4:
- A contract check draws, on both engines: an atlas cell switch, a
rotation of π (a half-white cell flips from above to below the
centre), scale 2 (about four times the area), scaleByDistance past
`far` (about a quarter), setCount shrinking the set, depth modes for
sprites 30 km under the ground ('always' and a disableWithinM past the
camera draw), a point with its dark outline, and a glTF model
(airplane.glb, minimumPixelSize 80, colorBlend replace) in magenta.
'normal' and a 10 m disableWithinM hide the buried sprite on Navara;
Cesium's billboards are not occluded by the app's photoreal tiles
(globe hidden; measured), so those two are asserted on Navara only.
- pickable: false: Cesium's GPU pick sees every primitive, so the
picker drops picks (and drill entries) of a set created with
pickable: false; Navara only registers pickable sets. The contract's
click check now clicks a pickable: false sprite on both engines.
- Navara resolves a GPU answer's batch id to the pick id when Navara
answers (the pick's own frame), not when the engine's click consumes
it: a set that reuses the instance in between still yields the
instance that was under the pointer.
Contract: Cesium 70/70, Navara 76/76.
Review of Task 3 (DPI-independent dashes; the shader change landed with
the overlay commit): qa-globe-contract --dpr=2 runs the suite on a
high-DPI page, and a new check measures a 16/16 px dashed line along its
middle row in CSS pixels: the dashes must be regular, and on Navara
16/16 within 2 px. The harness prints what each engine draws.
Measured: Navara 16/16 (period 32) at DPR 1 and 2. Cesium draws
16 on / 16 off (PolylineDash dashLength 32, pattern 0xff00, uniforms
checked on the primitive) as 14 on / 2 off with a 16 px period at both
ratios — a Cesium-side difference to look at before a layer relies on
pixel dashes (none does yet). At DPR 2 the Navara harness's
stars-at-midnight check counts 4 star pixels (its detector is tuned for
DPR 1); every suite check passes at both ratios.
Review of Task 4: the CPU line pick (shared with the sprite drill, hover
and the synchronous pick) took half the drawn width + 3 px, so a 1-2 px
trail needed a 3.5-4 px aim. Now within 8 px of the projected segments,
or half the width + 3 px for wider lines. Tested at 7.5 and 8.5 px from
a 1 px line; the contract suite's line click passes on both engines.
Review of Tasks 2–3: on Navara the overlays went through the look's
tone mapping and grading (magenta came out as 247/40/228, green as
147/228/89 in the cinematic look), where Cesium draws billboards and
polylines in the colours asked for.
src/globe/navara/overlay.js: a public Navara EffectDesc (gevOverlay)
inserted after toneMapping and before the gev sharpening, SMAA/FXAA and
final, whose pass renders one three scene over the tone-mapped input
buffer (in Navara's own Pass wrapper: Navara inserts a bare pass only
when it is an instance of its own postprocessing copy); it costs nothing
while the scene is empty. The chain has no depth buffer, so each overlay
material tests the scene depth itself (overlayDepth.js): its log depth
against Navara's MRT depth (RGBA packed), modes always / normal /
depth-fail, disableWithinM as a per-vertex escape. Sprites and points
(moverMesh.js) and line ribbons (lineMesh.js) live in that scene with
their per-frame work as overlay hooks; models stay Navara meshes, lit
and graded like the tiles. The sharpening now sits after the overlay
(Cesium's sharpen stage sharpens billboards too).
Also (review): Navara pixel dashes are measured in CSS pixels
(gl_FragCoord over uGevPixelRatio), and the line viewport uniform is
updated in place.
Measured: a magenta sprite draws 255/0/255. The contract suite's colour
checks are now within 40 of the asked colour on every channel on both
engines (were: dominant channels); Cesium 68/68, Navara 74/74 (its
sharpen-order check accepts the overlay between tone mapping and the
sharpening). Shell: cesium 23/23, cross 4/4; navara 23/25 — the two map
stack pictures from space fail on stddev 7.2/7.6 against 8, as on the
Task 3 commit run at the same hour (the cinematic sun follows the clock
into night over the reset view), not from this change.
qa-directions, qa-transit, qa-transit-recovery and qa-wind-canvas
launched a visible Chrome window. They now run headless unless
QA_HEADFUL=1 (`headless: process.env.QA_HEADFUL === '1' ? false : true`,
the same change as on the phase-4 branch).
Navara 0.2.1's transparent pass refreshes its copy of every scene light
each frame with copy(light, true). For the sun's cascaded shadow lights
(three-csm CascadedDirectionalLights) that copy clones every cascade, so
each frame brought new DirectionalLights with new ids and three's
WebGLLights uniforms cache (keyed by id) grew by about 1.2 KB a frame in
the looks whose sun casts shadows (minimal, photoreal).
src/globe/navara/cascadedLightCopy.js patches the copy to update the
cascades it has in place (pose, colour, intensity, target, shadow
settings and camera) when the counts match, and keeps the rebuild
otherwise; internals.js finds the class among the view's scene lights
(private view._scenes.light) and applies it when the globe is built.
Tests on three-csm's own class: the original copy changes the light ids,
the patched one keeps the lights and takes the values.
Post-GC JS heap (CDP HeapProfiler.collectGarbage every 10 s, the app on
?engine=navara rendering continuously at 60 fps): minimal 4.33 → 0.20
MB/min over 70 s and 0.06 MB/min over 180 s; photoreal 4.34 → 0.19
MB/min; cinematic (no shadow) 0.34. Added to the upstream asks.
src/data/selectionDispatcher.js: one engine click subscription with
picks (pick, drill 8), the press gesture (travel and duration, as
bindTrackingClickGesture) and one Escape listener for the layers that
move onto the engine. Owners register owns(id) (also in pickRegistry, so
layers still on their own handlers see the ownership) and onSelect /
onEmptyClick / onEscape. Rules of the existing handlers: another layer's
pick is not empty space; passThrough picks (trails) never take the
click; a drillThrough owner (local ADS-B) takes its object from under
another layer's; a drag selects nothing; deselection needs a clean click;
a pointer owned by a tool selects nothing. Tested on the fake engine:
own / foreign / empty / trail clicks, drill-through, drag and long press,
Escape, an owner without handlers, unregister and destroy. No layer uses
it yet (the *a tasks move them).
input.on('click'|'doubleClick'|'move', fn, { pick, drill }) delivers
{ …event, picked, drilled }: PickResult { id, owner, instance, primitive
(Cesium) } names the mover set (and instance) or line hit. One pick (and
one drill, as deep as the deepest listener) per event, shared by its
listeners; moves with picks are coalesced to one delivery per frame with
the latest position (src/globe/pickDelivery.js). Option checks in the
contract (normalizeInputOptions).
- Cesium: scene.pick / drillPick, and the picker names the owner: movers
map billboards, points and models to their set and instance, lines
their primitives to the line.
- Navara: a click with pick takes Navara's GPU pick of the same gesture
(featureClick; its pick helper answers on the same pointerup, usually
before the engine's click, so a fresh answer waits for it; otherwise
the click waits up to 250 ms, then the CPU pick). Navara 0.2.1 answers
clicks in quick succession with the first click's pick: a GPU answer
whose instance is not drawn near the click is stale and the CPU pick
answers. Hover, drill and the synchronous picker.pick/drillPick are CPU
picks (src/globe/cpuPicks.js) of pickable mover sets and pickable lines
(within half the width + 3 px), behind the globe excluded, nearest
first; lines are picked on the CPU after an empty GPU answer.
picker.clickStats() (Navara only) counts the answers and latencies.
- The fake engine picks its own movers and lines on the CPU unless
scripted.
- The contract suite clicks with real pointer events (puppeteer) on both
engines: a sprite is picked with its owner and instance, the map picks
nothing, two sprites in one place drill both, a line is picked, a
hover picks the sprite under it. Navara, 20 clicks: payload p50 2.8 ms,
p95 4.1 ms after the click (puppeteer dispatch included), 20/20 GPU
answers. The Cesium harness keeps the first-run card closed.
engine.lines.createLine({ id, widthPx, color, depthFailAlpha, dash
({ lengthPx, gapPx } | 'tactical'), arc ('none'|'geodesic'), modelMatrix,
pickId }) → a Line: setPositions (Cartesian3[] or a flat Float64Array),
setColor, setModelMatrix, show, destroy; lines.list() for QA. Options,
flat positions, geodesic densification (great circles of the geodetic
normals, height interpolated, one step per degree) and the registry are
engine-neutral (src/globe/lines.js); the fake engine keeps every line.
- Cesium: a Primitive of a PolylineGeometry (synchronous, rebuilt when
the positions change) with a PolylineMaterialAppearance in an
engine-owned collection; depthFailAlpha is depthFailAppearance with the
alpha scaled; pixel dashes are PolylineDash (16-bit pattern); the
tactical dash is the launches' selected-orbit shader under its own type
(launches keep theirs until Task 15a moves them onto engine.lines).
- Navara: a public MeshDesc (transparent pass, unlit) holding a ribbon
of one quad per segment, widened to CSS pixels in the vertex shader;
a second copy drawn with GreaterDepth and the alpha scaled is the
depth-fail part; dashes are cut in the fragment shader (pixels along
the screen direction, or the tactical pattern over the fraction along
the line); positions relative to the first point, the model matrix on
the group. Geodesic arcs are densified on the CPU. Not pickable yet.
- The contract suite draws a three-point line on both engines: magenta
along both segments, nothing off it, 1° east once turned by its model
matrix, gone when hidden; a line 30 km under the ground shows only its
depth-fail copy, dimmer than the line.
Main chunk 2,867,499 bytes (+7,197, +0.25 %: the Cesium lines).
engine.movers.createSet({ id, kind: sprite|point|model, capacity, order,
depthTest, sprite|point|model, pickable }) → a MoverSet: set(index,
fields) stores an instance (position, screen rotation, orientation, rgba,
scale, atlas cell, show, pickId) in flat arrays, commit() uploads the
changed range once and requests one render, positionsView() reads the
positions, destroy() removes it; movers.list() for QA. The options, the
store and the registry are engine-neutral (src/globe/movers.js); the fake
engine keeps them for layer tests.
- Cesium: one primitive per set in an engine-owned PrimitiveCollection
added with the first set, in `order`: sprites a BillboardCollection
(one image per atlas cell, NearFarScalar, disableDepthTestDistance),
points a PointPrimitiveCollection, models a Model per instance.
- Navara: a public MeshDesc per set. Sprites and points are one
InstancedMesh of a quad, faced to the screen and sized in CSS pixels in
the vertex shader from uniforms (the pick pass draws the same
footprint), atlas uv, rotation, colour and scale per instance, drawn in
the transparent pass unlit; offsets from an origin that follows the
camera past max(1 km, 10 % of its height). Models: the glTF once, one
InstancedMesh per mesh, minimumPixelSize/maximumScale on the CPU per
drawn frame, colorBlend in the shader. Pickable sets register a
PickableInstancedMeshWrapper; pickIds.js maps batch ids back to
instances (used by Task 4).
- The contract suite draws three 24 px sprites on both engines: centred
within 2 px of worldToWindow, hidden by show:false, recoloured, gone on
destroy, and no frames added once the commit has drawn.
- qa-engine-bench --scenario=movers: 10 000 synthetic aircraft
(src/bench/syntheticFlights.js, moved from the Navara spike with its
test), every instance moved and committed every frame. p95 Navara
(look=minimal) / Cesium: global 5.2/7.0 ms, city 5.6/9.9, orbit 6.0/7.4
(0.74, 0.57, 0.81; gate 1.1). Cesium is measured without its 60 fps cap.
Main chunk 2,860,302 bytes (+9,706, +0.34 %: the Cesium movers).
Review of Task 0: the live baseline could not be compared between
commits. qa-w1-baseline now records every /api response of each layer's
run (--record=DIR, DIR/<layer>.json), replays them through puppeteer
request interception (--replay=DIR; an /api request outside the
recording answers 503) with the page clock frozen at the recording's time
(evaluateOnNewDocument: Date.now and new Date(), hence JulianDate.now and
the app clock), and diffs two runs (--compare=A,B: counts, known objects'
positions within 1e-7° and 5 cm, screen points within 0.5 px, tracking
poses within 1e-6 relative). The rules live in src/tooling/w1Baseline.js
with tests.
Recorded once (qa-artifacts/w1-feeds, git-ignored), replayed on
d50eaa28 and on HEAD: the runs agree within the tolerances for flights,
military, satellites (counts, five known objects each, tracking poses)
and launches (count). Local ADS-B has no receiver and vessels no AIS key
here: both stay empty. This is the reference for the extraction tasks.
Review of Task 0:
- build/initialChunkGuard.js, a Rollup plugin in the browser build, fails
the build when an initial chunk (an entry and what it imports
statically) holds a module from node_modules/three, @navaramap/* or
postprocessing. Checked by forcing it on satellite.js, which the main
chunk does hold: the build fails naming the chunk and module.
navaraAssets.test now pins both build plugins.
- scripts/check-main-chunk.mjs is one script for both main-chunk checks:
the composition (text markers in the initial chunks, sizes) and, when
scripts/main-chunk-baseline.json exists, the phase-4 branch's gzip-9
budget, with its exports (checkMainChunk, measureMainChunk) so the two
branches merge into this file. The composition test moved to
src/tooling/mainChunkComposition.test.mjs to leave phase 4's
mainChunk.test.mjs its name.
- CI runs npm run check:main-chunk after each npm run build (unit,
browser-gate and Windows jobs).
Review of Tasks 0–1:
- The Cesium engine clock attaches its frame latch to viewer.clock.onTick
when the engine is created, so it runs before onTick listeners added
later (cameraVerbs installs its own after the engine exists). Before, it
attached on first use and would have run after them. A viewer without a
clock still latches lazily on the scene's preUpdate.
- GlobeClock lists what is not on the app clock yet: Cesium's viewer clock
(its lighting and property reads at currentTime), the launch replay
timeline and the mission orbit's GMST frame (Task 15a), the satellite
cloud's SGP4 and orbit bake (Task 14a), and wall-clock throttles. The
plan's T14a/T15a now carry those moves.
- freeze/offset/rate change now() at once and frameTime() from the next
frame; QA helpers request a render after moving the clock.
The phase-2 review fixes: look internals in internals.js, the groundFloor
resample throttle, tile height selection, the sharpen mirror, QA tile
cache limits, engine.groundFloor diagnostics. In navara/index.js both
sides are kept: the look gets internals.js's luminance uniforms and reads
the sun's time from the engine clock's frame time, so engine.clock stays
the one time source for the sun.
The Navara wheel check measures clearance against engine.groundFloor's
ground (threshold 29 m: the floor keeps 30 m), so tiles streaming under a
still camera cannot flake it. The tile cache identifies itself with the
repository URL, keeps at most two misses in flight and merges identical
ones.
sampleHeight collects hidden tiles only after the shown ones miss, with
no per-node allocation, and picks the finest by tile extent (Navara
exposes no geometric error), not per-mesh radius. The ground floor
resamples on a move only after 100 ms, and reports its own ground and
margin (engine.groundFloor, Navara-only diagnostics).
- 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 clock keeps its numbers in object fields (stored in place) instead of
closure variables, and its default wall clock is one module-level
function. Micro-measure (Node, --expose-gc, 200k calls): the flights
render-time arithmetic allocates about 25-35 B per call with the app
clock against 66-102 B with JulianDate.now/addSeconds; an engine tick
(beginFrame + ticked) about 20-30 B.
Flights and military keep their fix history in plain milliseconds
(timeMs, whole ms as the Date the JulianDate came from held) and read
"now" from the app clock: the render-delay time, bracketing,
extrapolation, the warm-up check and the trail seed are number
arithmetic (motion.js, tracking.js, snapshotRenderer.js), as is the turn
rate and the forward synthetic fix in data/motionModel.js, which no
longer imports Cesium. The JulianDate scratch fields in state.js and the
unused JulianDate.now() in queries.js go. Launches (mission frame, panel,
selection), the tracked satellite's SGP4 epoch and the celestial ring's
sun and moon read the app clock; where a Cesium property still takes a
JulianDate it is built from the app clock's now (as JulianDate.now did
from Date.now). Wall-clock throttles and feed receipt stamps stay on
Date.now; property reads at viewer.clock.currentTime (render, frozen at
boot) move with the render code in the *a tasks.
Tests that built JulianDate history fixtures now build ms ones with the
same instants (motionModel.test, flights.test, militaryFlights.test); new
tests show the military delayed position and the tracked satellite follow
the app clock (both fail on the previous code).
src/time/clock.js is the app's own time in ms since the epoch: by default
Date.now exactly (read at each call), with freeze/offset/rate/reset for QA
and tests, and one frame time latched per engine frame (beginFrame). The
contract gains engine.clock { now, frameTime, ticked }, in the fake engine
(a controllable wall clock, fake.advanceTime, fake.appClock), the contract
suite (one frame time for every listener of a frame, latched before
preUpdate, never decreasing), Cesium and Navara.
Cesium latches on the viewer clock's onTick, which CesiumWidget runs right
before scene.render, so scene listeners the app added before the engine
existed read the same frame time; the subscription appears on first use
and destroy removes it. The viewer clock itself is untouched: in the app
it never animates (shouldAnimate false, multiplier 1, its time frozen at
boot), and its time still drives Cesium's lighting as before. Navara
latches in the engine's handler of the view's preUpdate, and the look
reads the engine clock's frame time for the sun, so the app clock is the
one time source on Navara too.
src/time is a portable root in check-import-directions: no engine
packages, no browser globals.
scripts/check-main-chunk.mjs (npm run check:main-chunk) finds the main
chunk of a build (the Vite manifest's entry, or the module script
dist/index.html loads), follows its static imports and fails when any of
them carries three or Navara markers; it prints the sizes. Base build:
main chunk 2,850,229 bytes (gzip 881,783), no static imports, clean.
scripts/qa-w1-baseline.mjs records Cesium mode for the W1 layers (flights,
military, local ADS-B, vessels, satellites, launches): counts, five known
objects with positions and screen points, JPEGs (path, size, sha256) at
the global / New York (JFK) / orbit poses, a tracked object's camera pose
after 2 s and what its share link restores. Live sources until the
fixture sources of Task 8.
VisualEffects sends its sharpen state to engine.render.setSharpen when a
viewer exists too; the Cesium engine keeps it as state, and the Cesium
stage itself is unchanged.
qa-globe-contract checks the noon sky facing the horizon (daylight blue,
no star pixels) and stars at midnight; qa-engine-shell compares
sampleHeight at the Austin startup pose across engines and reports the
wheel floor's lowest frame. QA pages load OSM and keyless terrain tiles
through a disk cache with backoff on 429. Report updated.
The ground under a tilted camera is outside the frustum, where Navara
hides its tiles, so the ray found nothing. When the shown tiles miss,
the loaded hidden ones answer, the finest first (within 1.5 times its
radius, which keeps out the quadtree parent). At the Austin startup
pose it agrees with Cesium within 0.12-1.04 m.
The baseline and the style presets name ENGINE_SHARPEN_DEFAULT, which
resolves to 49 % on Cesium and 80 % on Navara. Share links and explicit
calls restore their value unchanged.
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.
The Navara engine now builds its own photoreal scene (aerial perspective,
tone mapping, SMAA) instead of the minimal sky-and-sun look. It costs about
5 ms a frame (S5); minimal stays available for benches.
Prettier on the 13 new test files that failed --check; format-scope.json
now lists every file phase 2 added (src/globe/**, engineChoice, navaraMode,
cameraAngles, the QA scripts and pages, build/navaraAssets and tests).
Two engine-neutral checks: pickPosition then worldToWindow lands within
1.5 px of the screen point (over New York, straight down and tilted;
points with no surface are skipped, at least one must hit), and
maps.setTerrain resolves for keyless terrain and rejects an unknown kind.
The fake engine now rejects unknown terrain kinds, as both engines do.
The Navara contract page shows OSM on keyless terrain before the suite,
since depth picks need a drawn surface.
Navara's attribution list is capped at 120 px, and the shell's data
credits register after the map's, so Google's copyright lines come first
and stay visible while the card no longer covers the left panels.
qa-engine-shell polls engine.surface.tilesLoaded() (true for 1.5 s, up to
90 s) before judging the picture and prints the load time per engine;
"wheel zoom stops above the ground" is a hard check on both engines
(height >= 20 m; on Navara >= 20 m above the sampled surface), and the
Navara known gap is gone.
chunkFileNames names the chunk holding src/globe/navara
navara-engine-[hash].js; chunking is unchanged (manualChunks would pull
modules shared with the Cesium entry into it and make the entry import
it). The Cesium main chunk stays 2,849,217 B.
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.
createDefaultMapSources takes the engine kind. On Navara, Google 3D is
available from the browser key alone (Navara builds the tiles itself and
has no ion route to them), so it is the default and the recovery stack
when a key is set; without one the default is Esri imagery. Bing (Cesium
ion imagery) has no Navara path and is unavailable with a reason. World
terrain still needs an ion token and falls back to the keyless terrain.
MapStackController passes the kind of the engine it is given; Cesium
sources are unchanged.
