@loaders.gl/draco

What is @loaders.gl/draco?

@loaders.gl/draco is a module within the loaders.gl framework that provides support for loading and decoding Draco compressed 3D geometries. Draco is a library for compressing and decompressing 3D geometric meshes and point clouds, which significantly reduces the size of 3D assets.

What are @loaders.gl/draco's main functionalities?

Loading Draco Compressed Data

This feature allows you to load Draco compressed data from a specified URL. The `DracoLoader` is used in conjunction with the `load` function from `@loaders.gl/core` to fetch and decode the compressed 3D geometry.

const { DracoLoader } = require('@loaders.gl/draco');
const { load } = require('@loaders.gl/core');

async function loadDracoData(url) {
  const data = await load(url, DracoLoader);
  console.log(data);
}

loadDracoData('path/to/draco/file.drc');

Decoding Draco Data

This feature allows you to decode Draco compressed data from an ArrayBuffer. The `parse` function from `@loaders.gl/core` is used along with the `DracoLoader` to decode the data into a usable format.

const { DracoLoader } = require('@loaders.gl/draco');
const { parse } = require('@loaders.gl/core');

async function decodeDracoData(arrayBuffer) {
  const data = await parse(arrayBuffer, DracoLoader);
  console.log(data);
}

// Assuming you have an ArrayBuffer of Draco data
const dracoArrayBuffer = new ArrayBuffer();
decodeDracoData(dracoArrayBuffer);

Other packages similar to @loaders.gl/draco

three

Three.js is a popular JavaScript library for creating and displaying 3D graphics in the browser. It includes support for loading and decoding Draco compressed geometries through the `THREE.DRACOLoader` class. Compared to @loaders.gl/draco, Three.js offers a more comprehensive suite of tools for 3D rendering and scene management.

draco3d

Draco3D is the official JavaScript implementation of the Draco compression library. It provides low-level APIs for encoding and decoding 3D geometries. While @loaders.gl/draco focuses on ease of use and integration with the loaders.gl framework, draco3d offers more granular control over the compression and decompression processes.
