war3-model

TypeScript-based mdl/mdx (Warcraft 3 model formats) converter/renderer

Demo

• MDL/MDX converter (also json-like structure-previewer)
• WebGL model previewer (png/jpg textures requires second drag&drop)
• BLP previewer (BLP1 decoder only)

Usage

npm i war3-model --save

MDL parsing/generation

import {parse as parseMDL} from 'war3-model/mdl/parse';
import {generate as generateMDL} from 'war3-model/mdl/generate';

let model = parseMDL('...');
let mdl = generateMDL(model);
console.log(mdl);

BLP => PNG node.js converter

import * as fs from 'fs';
import {PNG} from 'pngjs';
import {decode, getImageData} from 'war3-model/blp/decode';

let blp = decode(new Uint8Array(fs.readFileSync(process.argv[2])).buffer);
let imageData = getImageData(blp, 0);
let png = new PNG({width: blp.width, height: blp.height, inputHasAlpha: true});

// I don't know how to create PNG with existing data, so...
for (let i = 0; i < imageData.data.length; ++i) {
    png.data[i] = imageData.data[i];
}

fs.writeFileSync('out.png', PNG.sync.write(png));

MDL/MDX support

• All standart features like Sequences, Bones, Cameras, etc
• Multiple texture chunks (mdx only)
• Multiple sequences/nodes with the same name (not quite sure is it feature or not, but War3 actually contains such models)
• SoundTrack not supported

Renderer support

• Standart geometry/animation
• Custom team color setting
• ReplaceableId 1/2
• Global sequences
• Alpha blending and multiple layers
• TextureAnimation
• Billboarded/BillboardedLockXYZ, w/o DontInherit/CameraAnchored
• RibbonEmitter (w/o Gravity and TextureSlot/Color animation)
• ParticleEmitter2 (with Tail/Head/Both/Squirt(?))
• No light support (normals, light, Unshaded, etc)
• No render priority support (PriorityPlane and others)

BLP support

• BLP1 only (not BLP0 and BLP2 support)
• Decoder only, no encoder
• Direct & jpeg data
• Variable alpha (8/4/1/0 bit, but tested only 8/0)
• API for getting all mipmap level's data

Thanks
