Syntax

PointCloud.applyScaleStats(stats: ScaleStatsResult): void
pointCloud.applyScaleStats(stats);

Parameters

Name Type Required Description
stats ScaleStatsResult Yes Precomputed scale statistics used to update transform parameters.

Returns

void - No return value. The call applies side effects to runtime state and/or GPU resources.

const wgpu = await WasmGPU.create(canvas);

const pointCloud = wgpu.createPointCloud({ data: new Float32Array([0, 0, 0, 0.1, 1, 0, 0, 0.8]), scaleTransform: { mode: "linear", domainMin: 0, domainMax: 1 } });
const stats = { count: 2, finiteCount: 2, min: 0, max: 1, percentileMin: 0, percentileMax: 1, histogramBins: null };
pointCloud.applyScaleStats(stats);
console.log("updated");
