Model - Point cloud value#

API reference for src/nodeMethods/pointCloudValue on @huukhanhnguyen/model, reachable from ./compute.

See the Guide for the ModelJSON / evaluate pipeline.

API reference#

Signatures are generated from the live package .d.ts - not hand-written.

bounds#

function

World-space bounding box (min + max corner) of a point set.

bounds(points: unknown): { min: Point$1; max: Point$1; }

cluster#

function

Seeded k-means. labels is parallel to points and stable across runs for the same seed.

cluster(points: unknown, k: number, seed: number): { labels: number[]; centers: Point$1[]; }

convexHull#

function

Convex hull of a point set, taken in its own best-fit plane and returned in world space. Fewer than 3 points returns the input verbatim (no meaningful hull).

convexHull(points: unknown): Point$1[]

downsample#

function

Voxel-grid downsample (Open3D voxel_down_sample semantics): one representative per occupied cell of size spacing, that cell's own point centroid. Deterministic ordering.

downsample(points: unknown, spacing: number): Point$1[]

fitPlane#

function

Least-squares best-fit plane through a point set — the smallest principal axis (minimum spread) as the plane normal, through the centroid. Returns the SAME {point, normal} shape as nodeMethods/plane.ts's Plane, so it composes directly with every Plane.* function and any plane-typed arg.

fitPlane(points: unknown): { point: Point$1; normal: Vector; }

nearest#

function

The count closest points to query, distance ascending. count = 1 yields the single nearest point rather than a one-element array.

nearest(points: unknown, query: Point$1, count?: number): Point$1 | Point$1[]

normals#

function

Per-point normal via local PCA over the neighborCount nearest points. Returned Vector[] is parallel to points.

normals(points: unknown, neighborCount?: number): Vector[]

principalAxes#

function

Principal axes of a point set, longest spread first, as an orthonormal frame through the centroid with each axis's length the spread along it. Degenerate (empty) input returns the standard basis, all lengths 0.

principalAxes(points: unknown): { center: Point$1; axes: [Point$1, Point$1, Point$1]; lengths: [number, number, number]; }
