PointCloud.scaleTransform

Summary

PointCloud.scaleTransform reads the current scaleTransform value from this PointCloud instance. Use it to inspect runtime state without mutating resources.

Syntax

PointCloud.scaleTransform: ScaleTransform
const value = pointCloud.scaleTransform;

Parameters

This API does not take parameters.

Returns

ScaleTransform - Normalized scale-transform snapshot currently active on this object.

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 } });
const value = pointCloud.scaleTransform;
console.log(value);
