three-prwm-loader

A PRWM loader for Three.js

Packed Raw WebGL Model is a binary file format for nD geometries specifically designed for JavaScript and WebGL with a strong focus on fast parsing (from 1ms to 0.1ms in Chrome 59 on a MBP Late 2013). More information on this here.

Installing

With npm do:

npm install three-prwm-loader --save

Example

var PRWMLoader = require('three-prwm-loader')(THREE);
 
// instantiate a loader
var loader = new PRWMLoader();
 
// load a resource
loader.load('./models/mymodel.le.prwm', function onLoad (bufferGeometry) {
    var mesh = new THREE.Mesh(bufferGeometry, new THREE.MeshNormalMaterial());
 
    // add mesh to scene, etc.
    // scene.add(mesh);
    // ...
});

API

new PRWMLoader([manager])

Instantiate a loader for PRWM files.

Arguments

loader.parse(arrayBuffer [, offset])

Parse a PRWM file passed as an ArrayBuffer and directly return an instance of THREE.BufferGeometry.

Arguments

  • arrayBuffer: ArrayBuffer containing the PRWM data.
  • offset: Offset (in bytes) at which the PRWM file content is located in the ArrayBuffer. Must be a multiple of 4.

loader.load(url, onLoad [, onProgress[, onError]])

Parse a remote PRWM file and return an instance of THREE.BufferGeometry (through a callback).

Arguments

  • url: Url of the PRWM file to load. Any * character will be replaced by le or be depending on the platform endianness. (see the guidelines)
  • onLoad: Will be called when load completes. The argument will be the loaded BufferGeometry.
  • onProgress: Will be called while load progresses. The argument will be the XMLHttpRequest instance, which contains .total and .loaded bytes.
  • onError: Will be called when load errors.

PRWMLoader.isBigEndianPlatform()

Return true if the endianness of the platform is Big Endian.
