Moves the Cartesian3/Cartographic/Matrix3/Matrix4/Math calls of the vessel, satellite and Contacts (awareness) layers, plus flights controller/enrichment, to src/geo. The satellites-layer package boundary now owns the src/geo modules. Awareness keeps Cesium.Cartesian3.clone for the resolved subject position, which reaches the installations anchor (anchor.test pins a Cesium instance).
Move the Cartesian3/Cartographic/Matrix4/Transforms/Ellipsoid/Math calls of
the second batch (cockpit camera, context and controller; camera orientation
controls; application shell; location navigation; the annotation resolver
and engine; voice actions and pointer pick; the scene director; the embed
app) to src/geo. Behaviour is unchanged: same argument order, same `result`
semantics.
Kept on Cesium: out-of-scope classes (HeadingPitchRange, BoundingSphere,
Intersect, EllipsoidalOccluder, EasingFunction, SceneTransforms, JulianDate),
WGS84 where it goes into pickEllipsoid or EllipsoidalOccluder,
Matrix4.IDENTITY handed to lookAtTransform, and the Cartesian2 window
positions that reach scene.pickPosition: Cesium keys its per-frame pick
cache on windowPosition.toString(), which a plain object would collapse to
one "[object Object]" key.
The Contacts-subject harness in gevActions.test stubbed
Cesium.Cartographic.fromCartesian to place its subject; it now builds a real
subject position at the same coordinates with geo.cartesian3.fromDegrees.
The cockpit-controls and scenes package-boundary groups now own the src/geo
files.
Move the Cartesian3/Cartographic/Matrix/Quaternion/Transforms/Math calls of
the first batch (src/data motion, anchor, tracked-camera and icon helpers;
the root camera, locations, HUD, share-link, world-focus, ground-guard,
orbit and cloud modules; services/groundSnap) to src/geo. Behaviour is
unchanged: same argument order, same `result` semantics.
Kept on Cesium: out-of-scope classes (JulianDate, Axis, HeadingPitchRange,
BoundingSphere, Rectangle, EasingFunction, EllipsoidalOccluder with its
WGS84 and seed vector, SceneTransforms) and Matrix4.IDENTITY wherever it is
handed straight to a Cesium camera call (locations.test pins its identity).
synthesizeForwardKinematicsFix now returns a plain position, so the two
snapshot renderers clone it with the static Cesium.Cartesian3.clone instead
of the instance method. The package-boundary groups that reach these
modules now own the src/geo files.
An engine-neutral port of the CesiumJS 1.138 core maths gev uses: angle
maths, the WGS84 ellipsoid and geodetic coordinates, 2D/3D vectors, 3x3/4x4
matrices, quaternions and local east-north-up / heading-pitch-roll frames.
Formulas and operation order match Cesium, so outputs are bit-identical
(golden tests pin the centre, pole, -0 and quaternion branches).
- Values are plain-data instances of module-private constructors (own
enumerable fields only), so geo's hot functions keep their own V8 hidden
classes; matrices are plain column-major arrays Cesium accepts.
- Cesium's debug argument checks are ported with the same conditions, order
and DeveloperError messages, gated on DEBUG (src/geo/debug.js): on in Node
and the dev server, folded away by vite build, as Cesium's Build strips
them. A release-parity test compares DEBUG=false geo with Build/Cesium.
- The import-direction check forbids cesium and @cesium/* in src/geo;
CODE-BOUNDARIES.md and THIRD_PARTY_NOTICES.md document the port.
