Calculators (apps/live-map/src/calculators/):

  • eclipse.ts: findEclipseWindows(bodies, opts) — coarse scan with
    threshold-crossing detection, bisection to refine start/end,
    ternary search to find peak. Handles eclipse already in progress
    at scan-start. Uses sun = parentId===null body.
  • overpass.ts: findOverpasses(opts) — coarse scan for local distance
    minima, ternary refinement. Targets: vessel, body, ground station
    (lat/lon/alt → heliocentric).

UI:

  • panels/CalculatorsPanel.tsx: collapsible bottom-center panel with
    two tabs. Eclipse form: observer, eclipser, from UT → 3 windows.
    Overpass form: observer vessel, target kind+id, max dist → 5 passes.
  • timeFormat.ts: shared KSP-time formatters.

Live-map camera polish (apps/live-map/src/scene/):

  • camera.ts: CameraController — log-scale distance (z→exp(z)*1e8 m,
    range -3..12), spherical orbit around target, smooth lerp to
    selected body/vessel. Mouse wheel zooms, drag rotates, click
    raycasts for track toggle. Pointer-move-distance gate to
    distinguish click from drag.
  • glow.ts: additive shader-based atmospheric halo (rim-falloff
    fragment shader, BackSide) attached as child of body mesh.
  • layout.ts: bodyPositionAt now returns true heliocentric (walks
    parent chain); previous version returned parent-relative for
    non-root children which broke the eclipse calculator.

Bug fix:

  • packages/orbital-math/src/occultation.ts: sign of projection check
    was inverted. proj <= 0 correctly returns 0 (occluder behind
    observer), proj > 0 triggers eclipse computation.

Tests: 28 live-map tests (10 scene + 12 calculator + 6 camera),
45 total across the workspace, all passing.
