Three.js PLY file format loader to use with Node.js
Description
Node.js wrapper for three.js PLYLoader (currently three.js v0.137.0).
Original PLYLoader source code can be found here.
Beside some minor edits, I added an additional helper function for converting Node Buffer to ArrayBuffer (convenience-wise) and I put in place tests.
This library was developed as a JavaScript Module. The recommended use with CommonJS files is through dynamic imports.
Usage
const fs = require("fs");
const { join } = require("path");
const THREE = require("three");
(async () => {
// Import PLYLoader Factory
const { PLYLoaderFactory } = await import("threejs-ply-loader");
// Initialize PLYLoader Class
const PLYLoader = PLYLoaderFactory(THREE);
// Instantiate PLYLoader object
const plyLoader = new PLYLoader();
// Read 3D Model as PLY file format
const sourceFilepath = join(__dirname, "assets/cube.ply");
const fileBuffer = fs.readFileSync(sourceFilepath);
// Convert node file Buffer to ArrayBuffer
const fileArrayBuffer = plyLoader.bufferToArrayBuffer(fileBuffer);
// Parse 3D model into THREE geometry
const geometry = plyLoader.parse(fileArrayBuffer);
})();Example
An example is present in the examples folder. It will load a PLY file model and output its rendering to a PNG file. It can be run from a shell:
npm install
npm run example:cube-to-pngThe output image is going to located in examples/temp/vertex-colored-cube.png
Tests
They can be run from a shell:
npm install
npm testDevelopment notes
