# MindAR






MindAR is a web augmented reality library. Highlighted features include:



:star: Support Image tracking and Face tracking. For Location or Fiducial-Markers Tracking, checkout [AR.js](https://github.com/AR-js-org/AR.js)



:star: Written in pure javascript, end-to-end from the underlying computer vision engine to frontend



:star: Utilize gpu (through webgl) and web worker for performance



:star: Developer friendly. Easy to setup. With AFRAME extension, you can create an app with only 10 lines of codes



# Fund Raising



MindAR is the only actively maintained web AR SDK which offer comparable features to commercial alternatives. This library is currently maintained by me as an individual developer. To raise fund for continuous development and to provide timely supports and responses to issues, here is a list of related projects/ services that you can support.



  

    

      

        
Unity WebAR Foundation


        


          WebAR Foundation is a unity package that allows Unity developer to build WebGL-platform AR applications. It acts as a Unity Plugin that wraps around popular Web SDK.

# Target Images Compiler

You can compile your own target images right on the browser using this friendly Compiler tools. If you don't know what it is, go through the Quick Start guide 



https://hiukim.github.io/mind-ar-js-doc/tools/compile






# Roadmaps

1. Supports more augmented reality features, like Hand Tracking, Body Tracking and Plane Tracking



2. Research on different state-of-the-arts algorithms to improve tracking accuracy and performance



3. More educational references.



# Contributions

I personally don't come from a strong computer vision background, and I'm having a hard time improving the tracking accuracy. I could really use some help from computer vision expert. Please reach out and discuss.



Also welcome javascript experts to help with the non-engine part, like improving the APIs and so.



If you are graphics designer or 3D artists and can contribute to the visual. Even if you just use MindAR to develop some cool applications, please show us!



Whatever you can think of. It's an opensource web AR framework for everyone!



# Development Guide



#### Directories explained



1. `/src` folder contains majority of the source code

2. `/examples` folder contains examples to test out during development



#### To create a production build



run `> npm run build`. the build will be generated in `dist` folder



#### For development



To develop threeJS version, run `> npm run watch`. This will observe the file changes in `src` folder and continuously build the artefacts in `dist-dev`.



To develop AFRAME version, you will need to run `>npm run build-dev` everytime you make changes. The `--watch` parameter currently failed to automatically generate `mindar-XXX-aframe.js`. 



All the examples in the `examples` folder is configured to use this development build, so you can open those examples in browser to start debugging or development.



The examples should run in desktop browser and they are just html files, so it's easy to start development. However, because it requires camera access, so you need a webcam. Also, you need to run the html file with some localhost web server. Simply opening the files won't work.



For example, you can install this chrome plugin to start a local server: `https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb?hl=en`



You most likely would want to test on mobile device as well. In that case, it's better if you could setup your development environment to be able to share your localhost webserver to your mobile devices. If you have difficulties doing that, perhaps behind a firewall, then you could use something like `ngrok` (https://ngrok.com/) to tunnel the request. But this is not an ideal solution, because the development build of MindAR is not small (>10Mb), and tunneling with free version of `ngrok` could be slow.



#### webgl backend

This library utilize tensorflowjs (https://github.com/tensorflow/tfjs) for webgl backend. Yes, tensorflow is a machine learning library, but we didn't use it for machine learning! :) Tensorflowjs has a very solid webgl engine which allows us to write general purpose GPU application (in this case, our AR application). 



The core detection and tracking algorithm is written with custom operations in tensorflowjs. They are like shaders program. It might looks intimidating at first, but it's actually not that difficult to understand.



# Credits

The computer vision idea is borrowed from artoolkit (i.e. https://github.com/artoolkitx/artoolkit5). Unfortunately, the library doesn't seems to be maintained anymore.



Face Tracking is based on mediapipe face mesh model (i.e. https://google.github.io/mediapipe/solutions/face_mesh.html)
