createPointCloud#pointCount

Summary

createPointCloud#pointCount is the read-only active record count. CPU and Wasm data normally derive it from tuple count; external point buffers require it explicitly. Replacing point data may clear retained CPU colors whose tuple count no longer matches.

Syntax

PointCloud.pointCount: number
const value = pointCloud.pointCount;

Returns

The non-negative active point-record count.

Example

const canvas = document.querySelector("canvas");
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 } });
console.log(pointCloud.pointCount); // 2
