Methods

`Private` `Readonly`visit

visit(obj: Object3D): void
Parameters
- obj: Object3D
Returns void
- Defined in src/scene/projected-density.ts:185

configure

configure(deps: ProjectedDensityDeps): void
Parameters
- deps: ProjectedDensityDeps
Returns void
- Defined in src/scene/projected-density.ts:187

evaluate

evaluate(): boolean
Evaluate every committed data mesh under the root. Returns true when an evaluation ran (guard enabled, root/camera/buffer available).

Returns boolean
- Defined in src/scene/projected-density.ts:195

`Private`view

view(deps: ProjectedDensityDeps): ViewContext | null
The frame's snapshot: the injected one, or one rebuilt now from the getters.
Parameters
- deps: ProjectedDensityDeps
Returns ViewContext | null
- Defined in src/scene/projected-density.ts:217

`Private`visitObject

visitObject(obj: Object3D): void
Parameters
- obj: Object3D
Returns void
- Defined in src/scene/projected-density.ts:229

`Private`measureIfVisible

measureIfVisible(mesh: Mesh, bs: Sphere, camera: Camera, rec: NodeDensity): void
Parameters
- mesh: Mesh
- bs: Sphere
- camera: Camera
- rec: NodeDensity
Returns void
- Defined in src/scene/projected-density.ts:241

`Private`recordFor

recordFor(path: string): NodeDensity
Parameters
- path: string
Returns NodeDensity
- Defined in src/scene/projected-density.ts:256

`Private`measure

measure(mesh: Mesh, bs: Sphere, camera: Camera, rec: NodeDensity): void
Parameters
- mesh: Mesh
- bs: Sphere
- camera: Camera
- rec: NodeDensity
Returns void
- Defined in src/scene/projected-density.ts:274

get

get(path: string): NodeDensity | undefined
Last record for a node path, or undefined when never seen / pruned.
Parameters
- path: string
Returns NodeDensity | undefined
- Defined in src/scene/projected-density.ts:298

records

records(): IterableIterator<NodeDensity>
Live records (no copy) — for cheap summaries such as the Performance popover's thinning row.

Returns IterableIterator<NodeDensity>
- Defined in src/scene/projected-density.ts:303

snapshot

snapshot(): Record<string, NodeDensity>
Copy of every record, for getPerf().density.

Returns Record<string, NodeDensity>
- Defined in src/scene/projected-density.ts:308

reset

reset(): void
Forget every record (tests, dataset teardown).

Returns void
- Defined in src/scene/projected-density.ts:315
