Glasses Virtual Try-on Widget
Offer glasses virtual try-on to your users with this JavaScript widget. It can be easily integrated into an e-commerce website or into a mobile web application with a few lines of code. The experience is in real-time: the user see his face like in a mirror, but with glasses on.
You can find more information in Find & contact me.
Table of contents
Features
- real-time web based glasses virtual try on,
- light reconstruction (ambient + directionnal),
- very robust to:
- lighting conditions (back light, side light),
- facial variations (bearded people, hair partially covering the face, ...),
- works both on mobile (IOS, Android) and desktop,
- lightweight (2.1MB transferred for the demo including 3D models),
- high end 3D engine with:
- physically based rendering (PBR),
- raytraced shadows,
- deferred shading,
- temporal antialiasing.

Glasses 3D models
From GlassesDB
Glasses models are stored on the Jeeliz GlassesDB. Each model is identified by a unique SKU. You can check the different models available by opening glassesSKU.csv file.
As a static file
You can convert your own glasses GLTF 3D Model to a proprietary JSON file accepted by this widget using Jeeliz Glasses Studio 3D. You can download:
You can use both models from GlassesDB and your own static models. Glasses Studio 3D is a free application and you keep the IP on your exported 3D models. Unlike this widget, Glasses studio 3D works:
- Only on desktops, with a fullHD screen resolution (1920x1080),
- Your GPU device needs to be able to do MRT (Multi Rendering Targets) on at least 4 targets (i.e. it may not work on deprecated or very cheap hardware).
However, the capabilities of Glasses Studio 3D are below what we offer with GlassesDB. This is a comparison:

Misc
Test GlassesDB SKU availability
In some cases, SKU can be generated dynamically from the backoffice of the glasses e-commerce website. It can be <glassesMakerAsPrefix>_<collection>_<modelId>
. We need to test if this SKU is in GlassesDB in order to display the Virtual Try-on button to the user.
To do this, request with GET
or POST
method (using an XMLHttpRequest
for example):
https://glassesdbcached.jeeliz.com/testSku/<skuToTest>
You can test it here:
Compatibility
- If
WebGL2
is available, it usesWebGL2
and no specific extension is required, - If
WebGL2
is not available butWebGL1
, we require eitherOES_TEXTURE_FLOAT
extension orOES_TEXTURE_HALF_FLOAT
extension, - If
WebGL2
is not available, and ifWebGL1
is not available or neitherOES_TEXTURE_FLOAT
orOES_HALF_TEXTURE_FLOAT
are implemented, the user is not compatible with the real time video version.
If a compatibility error is triggered, please post an issue on this repository. If this is a problem with the camera access, please first retry after closing all applications which could use your device (Skype, Messenger, other browser tabs and windows, ...). Please include:
- a screenshot of webglreport.com - WebGL1 (about your
WebGL1
implementation), - a screenshot of webglreport.com - WebGL2 (about your
WebGL2
implementation), - the log from the web console,
- the steps to reproduce the bug, and screenshots.
If the user was not compatible or refuses to share its camera video stream, an image based fallback version was available til January 2020. The server side webservice generating the rendering has been undeployed.
If the user does not want to share its camera or if its implementation of WebGL is too minimalistic, a FALLBACKUNAVAILABLE
error will be triggered.
Optimization
If you meet some performance issues, please first:
- Check that you are using the latest main script (
/dist/jeelizNNCwidget.js
), - Check that your browser is updated (Chrome is advised), check that your graphic drivers are updated,
- Enter
chrome://gpu
in the URL bar and check there are no major performance caveats, that hardware acceleration is enabled, that your GPU is correctly detected,
The performance is adaptative. We do as many detection loops per rendering till we reach a maximum value (7
). If we cannot reach this value, the GPU will be running at 100%. The closer we are to this maximum value, the less latency we will observe.
So it is normal that the GPU is running at 100%. But it may be annoying for other parts of the application because DOM can be slow to update and CSS animations can be laggy.
The first solution ( implemented in Jeeliz sunglasses web-app ) is to slow down the glasses rendering once the user has clicked on a button using:
JEELIZVTO.relieve_DOM(<durationInMs>)
For example,JEELIZVTO.relieve_DOM(300)
will free the GPU during 300 milliseconds.
If you need to slow down the rendering to free the GPU during an undertermined period of time, you can use:
JEELIZVTO.switch_slow(<boolean> isSlow, <int> intervalMs)
Where intervalMs
is the interval in milliseconds between 2 rendering loops.
Hosting
This widget access the user's camera video stream through MediaStream API
. So your application should be hosted by a HTTPS server (even with a self-signed certificate). It won't work at all with unsecure HTTP, even locally with some web browsers.
