PointCloud.setPointsBuffer

Summary

The replacement buffer is borrowed by default. Pass { ownBuffer: true } to transfer destruction responsibility to the pointcloud; replacing or destroying the object then destroys that owned buffer exactly once. The call replaces CPU and Wasm point sources, sets pointCount, and clears retained point records.

Syntax

PointCloud.setPointsBuffer(buffer: GPUBuffer, pointCount: number, opts?: { ownBuffer?: boolean }): void
pointCloud.setPointsBuffer(buffer, pointCount, opts);

Parameters

Name Type Required Description
buffer GPUBuffer Yes GPUBuffer handle used as an external data source.
pointCount number Yes Number of points represented by the supplied data source.
opts { ownBuffer?: boolean } No Set ownBuffer: true to transfer buffer destruction responsibility.

Returns

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

Type Details

// No additional descriptor expansion is required for this signature.

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 buffer = somePointBuffer;
const pointCount = 2;
pointCloud.setPointsBuffer(buffer, pointCount);
