// Raycast vehicle on terrain — a Meep example.
//
// A toy car drives over a large, gently rolling heightmap world. The terrain is a
// Terrain component whose `samplerHeight` is filled with simplex noise; that same
// coarse sampler is wired into a HeightMapShape3D (collision) and read with
// Catmull-Rom by a finely-tessellated mesh (visuals), so smooth hills fall out of
// a small height field. The car is a built-in RaycastVehicle — four suspension
// rays, no wheel colliders — driven from an InputController, with a 3rd-person
// spring camera that follows the car's heading, and a flip/out-of-bounds respawn.

# raycast-vehicle

A toy car drives over a large, gently rolling heightmap world. The terrain
heights come from seeded simplex noise written into a `Terrain` component's
`samplerHeight`; the engine's `TerrainSystem` builds and draws the terrain
(one splat layer textured with a baked grid tile), and the same sampler is wired
into a `HeightMapShape3D` collider so the surface you see matches the surface you
drive on. The car is the built-in `RaycastVehicle` — four suspension rays, no
wheel colliders — steered from an `InputController`, with a
3rd-person spring camera that follows the car's heading and an automatic respawn
if it flips or leaves the world. Its cabin, wheels, headlights, brake lamps and
turn indicators are all attached as a small scene graph with `EntityNode`, and 64
light crates are scattered across the terrain for it to shove around.

Controls: **W / S** drive and reverse, **A / D** steer, **Space** brakes
(arrow keys work too). The brake lamps light while braking or reversing and the
indicator on the side you steer toward lights up. Click the view to give it
keyboard focus.

## Run locally

```bash
npm install
npm run dev
```

## Build

```bash
npm run build
```

Output goes to `../../public/examples/raycast-vehicle/demo.html`.

## What this demonstrates

- **Heightmap collision from a height sampler** — `HeightMapShape3D.from(sampler,
  sizeX, sizeY, sizeZ)` turns a `Sampler2D` of heights into a non-convex collision
  surface. We fill `Terrain.samplerHeight` with two octaves of
  `create_simplex_noise_2d` and hand it straight to the shape; the static collider
  sits at the origin, centred under the terrain footprint.
- **Engine terrain rendering** — the `TerrainSystem` meshes the Terrain off-thread
  (a build worker), tessellating each cell `Terrain.resolution`× from the height
  field, and puts each built tile into the Shade scene as a meshlet-encoded mesh.
  Texturing is a full-screen pass after the G-buffer rather than a material: one
  splat layer painted with a baked grid tile (`public/textures/ground-grid.png`,
  loaded through the asset manager as `GameAssetType.Image`).
- **Matching what you drive on to what you see** — both the mesh and the collider
  read the same `samplerHeight` with the same Catmull-Rom filter, but they tessellate
  it at *different* resolutions: the render mesh at `size × resolution`, and the
  collision narrowphase at the *sampler's* own resolution (one quad per sampler cell).
  If the sampler is coarser than the render, the car ends up colliding with a coarse,
  faceted version of the smooth surface it sees — drifting up to ~2 m apart on a hilly
  field. So we size the sampler to the render grid (`samplerHeight` is
  `cells × resolution` per side) and keep `resolution` modest: the smooth hill shape is
  baked into the height *data* rather than relying on interpolation to invent it, the
  render and collision tessellate the same grid, and the car drives on exactly what's
  drawn (settled gap ~2 cm instead of metres).
- **Pushable rigid bodies** — 64 light dynamic boxes are scattered over the terrain
  from a fixed seed (so the layout is reproducible), each a single entity: a
  `BoxShape3D` collider and a mesh sharing one physics `Transform64`. They drop onto the
  heightmap, settle, sleep, and wake when the car (or a neighbouring box) shoves them —
  the world is a sandbox to bump around, not just a track.
- **Ambient occlusion with nothing to bake** — the hollows between these hills
  darken on their own: Shade computes ambient occlusion in the frame (GTAO, on by
  default). Nothing is precomputed and there is no lightmap to wire up.
  (`Terrain.buildLightMap()` throws; there is no terrain AO bake.)
- **Shadows** — lights are built with `EngineHarness.buildLights({ castShadow: true })`
  and that is the whole configuration. `sunShadowDistance` is not passed: it has
  no effect, since Shade fits its own shadow frustum per frame.
- **Photometric lights** — a `Light`'s `intensity` is a real unit under Shade:
  candela for POINT/SPOT (the shader's inverse-square step turns it into lux at the
  receiver) and lux for the sun. So a lamp's number follows from the distance it has
  to work over — `I ≈ 0.9 · d²` matches the 0.9 lx sun at `d` metres, which puts the
  headlights near 110 cd and the rear lamps near 2. The same scale governs the
  emissive lens spheres, whose radiance is a fraction of what the terrain reflects.
- **A scene graph with `EntityNode`** — everything that rides with the car (the
  cabin box, four cylinder wheels, two SPOT headlights pitched down like a dipped
  beam, two red POINT brake lamps with lens spheres, two orange POINT turn
  indicators with lenses) is added as a child of the car entity via `EntityNode`
  — sugar over `TransformAttachment` + `ParentEntity`. Each child carries a local-offset
  `Transform64`; the `TransformAttachmentSystem` re-derives its world pose as
  `car ∘ offset` whenever the car moves, and because that dispatches the transform
  change-signals, the meshes and lights follow with no per-frame bookkeeping. A
  child's local `Transform64` carries rotation too, which is how the wheels lie across
  the car: the cylinder primitive's axis runs along Y, and the wheel node is rolled a
  quarter turn about Z rather than the geometry being pre-rotated.

  Only the lamp *intensities* are animated, from the input flags — and only the
  lights, not the lens materials. A Shade material is packed into the GPU's resident
  material buffer the first time it is drawn and there is no invalidation hook, so
  animating a material field would never reach the shader. The lenses glow at a constant, modest radiance; the brake and indicator
  *lights* are what switch.
- **A toy-car silhouette** — the chassis collider is a single box; a smaller cabin
  box rides on top of it and the wheels and lamps hang off it, so it reads as a car
  rather than a brick. The cabin is a second attached entity rather than geometry
  merged into the body: Shade has no `mergeBufferGeometries`, and since the car
  already carries an `EntityNode` hierarchy, one more cosmetic part bolted on says
  the same thing without hand-concatenating attribute arrays. All of it is cosmetic
  and never touches the physics — the body box is the only collider.
- **Flip / out-of-bounds recovery** — a per-frame check watches the car's up-vector
  and angular speed: if it's overturned *or* tumbling for a sustained ~2 s (patient
  enough that a dramatic roll can play out and sometimes recover on its own) it's set
  back down right-side-up, keeping its heading, over the spot where it ended up; if it
  falls out of the world or gets launched skyward it returns to the centre. Either
  way its velocities are zeroed.
- **A decoupled spring camera** — instead of a free orbit controller, the camera's
  Transform64 is driven each frame. It trails a point behind and above the car
  *along the car's ground heading* (the forward vector flattened onto the ground,
  which drops pitch and roll), eased on a spring so bumps and quick turns read as
  smooth lag. It looks ahead with world-up, so the downward tilt is purely
  geometric and the view never inherits the car's pitch or roll. Setting the
  Transform64 with `.set()` / `.lookRotation()` fires the change-signals
  `CameraSystem` watches, so the camera follows without any attachment. There is no
  `Matrix4` in meep and none is wanted here: `Quaternion.lookRotation(forward, up)`
  builds exactly the basis (`up × forward`, `forward × right`, `forward`) the view
  needs, in one call.
- **Render interpolation (engine `InterpolationSystem`)** — physics runs on a fixed
  1/60 step, but a display can refresh faster (or unevenly), so a body's transform
  only advances on the frames a step fires — which on its own makes the car (and the
  camera following it) stutter at 60 Hz on a 120/144 Hz screen. The engine's built-in
  `InterpolationSystem` solves this: tag the chassis with an `Interpolated` component
  (carrying the shared `POSE_INTERPOLAND`) and wire `physics.interpolationLog =
  interpolation.log`. The `PhysicsSystem` then records an authoritative pose snapshot
  per tick into the log (and restores from it at step start, so the solver always
  integrates from truth, never an interpolated pose); each render frame the
  `InterpolationSystem` blends the chassis `Transform64` between the last two ticks by
  `EntityManager.getFixedStepAlpha()` and writes the smoothed pose back into the live
  `Transform64`. Because that write fires the Transform64 change-signals, the mesh, the
  `EntityNode` attachments, and the chase camera (which just reads the chassis
  Transform64) all move at the full refresh rate for free — no separate visual entity,
  no hand-rolled interpolation buffer. Teleports go through `physics.setPose(...)`,
  which flags the component's `snap` so the renderer doesn't slide across the jump.
- **The built-in RaycastVehicle** — `new RaycastVehicle(physics, chassisBody,
  chassisTransform)` plus four `addWheel({...})` calls. Each wheel is a suspension
  ray cast against the world, not a collider; the controller applies spring,
  damper, and tyre-friction forces to the chassis. It's stepped with
  `vehicle.update(dt)` from a `System.fixedUpdate` registered *before* the
  `PhysicsSystem`, so forces land before the step that integrates them.
- **Tuning for stability** — the chassis keeps a low centre of mass; the
  suspension is slightly under critically damped *and* kept within the
  explicit-integration stability limit (`c·dt/m < 1`) so it settles instead of
  bouncing.
- **Speed-sensitive steering** — a grippy, punchy car would roll in a hard turn at
  speed, so the steering lock is capped to whatever keeps cornering acceleration
  (`v²·tanθ / wheelbase`) below the rollover point: full lock when slow and
  maneuverable, gentle at speed and stable. That lets the drive force and tyre
  friction be cranked for a brisk launch without the car tipping over.
- **Input via `InputController`** — keyboard keys are bound by path
  (`keyboard/keys/w/down`, `.../up`, …) to listeners that flip control flags, and
  `InputControllerSystem` wires those bindings to the live device signals. The
  vehicle system reads the flags each fixed step.
- **Determinism** — the terrain seed is fixed, so the hills (and therefore the
  whole simulation) are reproducible run to run.
