XR Animator, inherited from my previous desktop gadget project known as System Animator, is a video/webcam-based AI motion capture application designed for VTubing and the metaverse era. It uses the machine learning (ML) solution from MediaPipe and TensorFlow.js to detect the 3D poses from a live webcam video, which is then used to drive the 3D avatar (MMD/VRM model) as if you are controlling it with your body. It can be used for VTubing and various XR/3D purposes.
It has a variety of motion tracking options. You can choose to track the face, full body, or something in between (any combination of face/body/hands).
The web app version works on all major web browsers both on desktop and smartphone. On browsers supporting both web worker and OffscreenCanvas (e.g. Chrome), it can achieve 60fps visual rendering and 30fps body pose detection on a mediocre PC. On smartphones with limited processing power, you may want to use limit its usage on face tracking.
The Windows/Linux app version (powered by Electron) is also availabe for download, which provides a few extra features (e.g. VMC-protocol, transparent background) available only in a native-OS environment.
-
Support full-body AI motion tracking using a single webcam or media file (image/video)
-
Support "Perfect Sync"/ARKit-compatible 52 blendshapes for realistic face tracking
-
Support using any MMD/VRM model as your 3D avatar
-
Record mocap motion and export it to BVH or VMD motion format
-
Support loading VMD/FBX/BVH format 3D motions
-
Export FBX/BVH motions to VMD format
-
Customize the background and 3D scene with 2D image/video , 3D panorama and 3D objects (.x/.glb format)
-
Support VMC-protocol to animate a 3D model elsewhere in other VMC-enabled applications such as VSeeFace, Unity and Unreal Engine (Electron mode only)
-
Support frameless window with transparent background on video capture apps such as OBS (Electron mode only) (*)
-
Support AR (Augmented Reality) on Android Chrome browser
Check out these YouTube video demos and watch XR Animator in action!
(*) - To capture the web app version of XR Animator on OBS without the browser UI, you have to open XR Animator on OBS browser. A few extra command line parameters on OBS are required to allow camera access. Details
XR Animator has relatively low system requirements, making it usable on a wide range of devices, including laptops and even smartphones. On an entry-level PC with GTX1650-class GPU running XR Animator with full body mocap, you can expect 20+ fps on pose/fingers tracking, 40+ fps (capped at 30) on face tracking, and 60fps on 3D rendering.
However, if you are using a laptop but you are experiencing lower-than-expected frame rate, the app may be using the slower integrated GPU. This is a pretty common problem for laptop users. Configure your graphics card settings and make sure that the faster dedicated GPU is used. Check out the article below if you don't know how.

XR Animator and some other demos of System Animator Online support the "Augmented Reality" (AR) mode on mobile phones, which renders the 3D models that appear as if they exist in the real world. The AR mode requires mobile phones that support Google's ARCore technology, Chrome browser and the new WebXR API. Follow the steps below.
-
Check here for a list of ARCore-supported devices and see if your device is supported.
-
Install Google Play Services for AR (ARCore) on Google Play.
-
Install Chrome browser for Android.
Are you ready for the AR experience? Check out the online version of XR Animator on your Android Chrome browser!
After the page has been fully loaded, click on the little phone button on the top-left (or bottom-left) menu to activate the AR mode. Once the AR mode is enabled, you will see what your phone's camera is showing. Move your camera around the ground where you want to place the 3D model, and a white circle should apppear. Double-tap on the screen, and the 3D model will be placed over the white circle. Double-tab again to re-summon the white circle if you want to place the model elsewhere.
Check out these YouTube videos for demonstration.
XR Animator also supports the AR selfie feature, using both the front camera (for AR) and the selfie camera, allowing you to take a selfie with the 3D avatar in AR mode.
Before you enter the AR mode, you need to double-click the "Selfie camera" icon and enable the selfie camera first. Then you can toggle the selfie camera at any time during the AR session. By default, avatar is always displayed in front of you in selfie mode. Double-click the "Segmentation AI" icon to enable the AI mode, which detects your shape inside the camera, allowing your avatar to blend into the background and appear behind you. Note that the AI mode is SLOW. You will probably need the latest Android phone to get a smooth frame rate.
You may also use the "Segmentation AI" on PC directly and display the avatar behind you without going through the AR mode.
Lastly, click the Snapshot icon and a still photo will be generated. This can be saved into your phone for whatever purpose you want, showing off to your friends perhaps!

The future of XR Animator relies on your support🙇 Some IRL family issues have significantly increased my financial burden. While it was fun to develop the app, financial return was next to minimal. Reality forces me to evaluate the sustainability of this project, or soon I will have to give up...😢
If you like XR Animator, please consider making a donation🙇 Or even better, join my membership with perks such as EARLY ACCESS to the latest version XR Animator (at least one month ahead of the public release on GitHub), insider stories/tips and other benefits🎁 Sponsor us, and help keep this project free and sustainable🙏

System Animator was originally a desktop gadget project, born more than 10 years ago. The latest version, System Animator Online, is a major version advancement with focus on working as a web app instead of being just a desktop gadget. It fully supports MikuMikuDance (MMD) models and motions, as well as the latest VRM models and FBX/BVH motions, to create an immersive 3D environment.
It's hard to describe what System Animator Online can do in a few words. From a simple animated CPU meter to an interactive 3D music visualizer, a simple AR gadget on your phone to a full-body motion tracking app on your PC, the possibility is endless.

System Animator was born more than 10 years ago as a personal and tiny 100-line-ish JavaScript desktop gadget project for Windows Vista which shows an animated rocket Anime girl as a CPU meter (the animation is still in XR Animator).
As time goes by, I decided to add more features, multi-purpose system meter, music visualizer, 3D/MMD support, animated wallpaper engine, RPG engine and eventually what you see in XR Animator. The codebase has grown exponentially while the core is still an Internet-Explorer-based JavaScript gadget, and things were becoming more and more clumsy, to a point when I had to decide whether to rewrite everything from scratch to match the modern coding standard (open source, module based, etc). However, I gave up and decided to carry on with what I have written, as a total restart would require too much time and efforts, probably not worthy as a personal project. Besides, as the rule of programming says, "If it works, don't touch it" LOL
Eventually, I decided to put the project on Github for my own convenience, but technically speaking you can consider it open source, though I have to admit that some of the codes are outdated, clumsy and confusing. Everything is fine if you are just an end-user of XR Animator/System Animator as an app, but if you want to build your own things from my codes, be warned that they can be pretty incomprehensible LOL
