Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const scene = wgpu.createScene();
const pc = wgpu.createPointCloud({ pointCount: 0, scaleTransform: { mode: "linear", domainMin: 0, domainMax: 1 } });
pc.visible = true;
scene.add(pc);
scene.traverseVisiblePointClouds((cloud) => {
