Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Source MDL

This package can read source engines MDL files. To parse a model, it needs the VTX, VVD and MDL file.

It may not work with every model. It was tested with models from Portal 2.

After the model was imported, it can be exported in GLTF format. This conversion is lossy. Prop data like surface property, mouths, eyes and special source stuff will not be exported.

Currently it does not support bones or animations!

Demo

How to use

const MDL = require('./src/MDL.js');
const fs = require('fs').promises;

(async () => {
  // Read files or get the buffers from somewhere else
  let mdlData = await fs.readFile('./test/candles.mdl');
  let vtxData = await fs.readFile('./test/candles.dx90.vtx');
  let vvdData = await fs.readFile('./test/candles.vvd');

  // Create an MDL instance
  let model = new MDL();

  // Import the three buffers
  model.import({mdlData, vtxData, vvdData});

  // If you want, look at some metadata
  console.log(model.getMetadata());

  // Export as GLTF
  await fs.writeFile("test/test.gltf", JSON.stringify(model.toGLTF()));

  // Export as OBJ
  await fs.writeFile("test/test.obj", model.toObj());

  // You can import only the MDL buffer if you are only interested in metadata without geometry
  let modelNoGeometry = new MDL();
  modelNoGeometry.import({mdlData});
  console.log(model.getMetadata());
})();

Export

This module can convert MDL to different formats. | Format | Geometry | UVs | Armature | Animations | ----------------------------------------------------------|-------------|-----|----------|----------- | GLTF | Yes | Yes | No | No | OBJ | Yes | Yes | No | No | XMODEL (exporter by johndoe) | Yes | Yes | No | No

Or you can create your own exporter with the object obtained by model.getData() or use an external GLTF/OBJ to anything converter.
