cloudBounds#

const cloudBounds: (points) => Float64Array = wasm.point_cloud_bounds

[minX, minY, minZ, maxX, maxY, maxZ] — the TS {min, max} flattened.

Parameters#

points#

Float64Array

Returns#

Float64Array

cloudCentroid#

const cloudCentroid: (points) => Float64Array = wasm.point_cloud_centroid

Parameters#

points#

Float64Array

Returns#

Float64Array

cloudCluster#

const cloudCluster: (points, k, seed) => Float64Array = wasm.point_cloud_cluster

k-means, packed:

[0] = point count n (= the label count)
[1 .. 1 + n] = each point's cluster label
then the centers, 3 numbers each

Labels come back as f64 like everything else on this boundary; they are small non-negative integers, exactly representable.

Parameters#

points#

Float64Array

k#

number

seed#

number

Returns#

Float64Array

cloudConvexHull#

const cloudConvexHull: (points) => Float64Array = wasm.point_cloud_convex_hull

Parameters#

points#

Float64Array

Returns#

Float64Array

cloudDownsample#

const cloudDownsample: (points, spacing) => Float64Array = wasm.point_cloud_downsample

Parameters#

points#

Float64Array

spacing#

number

Returns#

Float64Array

cloudFitPlane#

const cloudFitPlane: (points) => Float64Array = wasm.point_cloud_fit_plane

[px, py, pz, nx, ny, nz] — the TS {point, normal} flattened, the same order plane_from_point_normal takes them in.

Parameters#

points#

Float64Array

Returns#

Float64Array

cloudNearest#

const cloudNearest: (points, x, y, z, count) => Float64Array = wasm.point_cloud_nearest

The count closest points, distance ascending. count = 1 (the TS default) yields exactly one point — 3 numbers.

Parameters#

points#

Float64Array

x#

number

y#

number

z#

number

count#

number

Returns#

Float64Array

cloudNormals#

const cloudNormals: (points, neighbors) => Float64Array = wasm.point_cloud_normals

One normal per input point, parallel to points. neighbors is the TS neighbors argument (its default is 12).

Parameters#

points#

Float64Array

neighbors#

number

Returns#

Float64Array

cloudPrincipalAxes#

const cloudPrincipalAxes: (points) => Float64Array = wasm.point_cloud_principal_axes

15 numbers: center (3), then axes[0..3] (9), then lengths (3).
