Create pick registries and selection dispatchers for each scene attachment,
publish them through scene.services, and release their predicates and input
subscriptions before parking the renderer. Resolve layer ownership with the
attached engine so identical layer IDs in simultaneous scenes cannot overwrite
or remove one another. Re-register retained ALPR and cyclone picks on attachment,
and resolve voice pointer picks against the engine that supplied the pick.
Preserve Cesium's selection, sibling ownership, inert trails, touch expansion,
drag and long-press rules on both engines. Extract the unchanged gesture
predicates so portable picking does not acquire a native input dependency.
Exercise scene isolation, teardown and reattachment on fake and headless Cesium
engines, retaining the existing layer assertions.
No coupling count falls or grows. Cesium and Navara renderer lines remain 0 and
189; external Cesium imports 3; viewer lines 910; Navara kind checks 2; engine
sniff calls 0; extension reads 3; ground passes 1; SDK loads 3; screen-handler
files 4; engine-name lines 33.
- Mapped Installations: one display holds the single copy of the logic
the Cesium and Navara renderers each had (renderable records, painting,
the selection fill, floors, named markers, selection). Discs are point
movers, outlines ground corridors and the selection fill a ground
polygon. Cesium's behaviour wins where they drifted: named areas draw
their outlines (Navara dropped them), discs sit under the moving
contacts, and outlines and the fill pick their site.
- Global Context: the range ring is a halo and a core line on
engine.lines and the awareness logic no longer imports Cesium. The
animated pulse disc, which no primitive draws yet, sits behind one
seam, render/pulseDisc.js, with a Cesium and a Navara backend.
- Datacenters and dams: one display on movers, lines and ground sets
with Cesium's LOD, motion probe, floor sampling and card cohort;
localGeojsonCore.js keeps only the engine-free card and record code
(1381 to 329 lines).
Coupling: layer renderer lines fall from 1011/4832 to 351/3349
(Cesium/Navara), `viewer` lines from 1745 to 1591,
ScreenSpaceEventHandler files from 8 to 6, Navara ground passes from 5
to 4.
