Overview
WebAR is an Augmented Reality Experience in Web Browsers instead of a Mobile App. It provides Web-Based AR experience by using technologies like HTML, WordPress. In simple words, you just need a phone to access it.
Create a Simple Web Page
Add AR Button
This button will be hidden on desktop devices but will be visible on smaller devices which supports AR functionality.
Script AR Button
<!-- AR Kit For Show Button Android and Ios -->
<script type="text/javascript">
function enhanceWithARQuickLook() {
// enhancement function
function addEnhancement(){
var name = "ar-fp";
var elements = document.querySelectorAll("[data-"+name+"]");
function wrap(instance, filepath) {
var wrapper = document.createElement("a");
wrapper.setAttribute("href", filepath);
wrapper.setAttribute("rel", "ar");
instance.removeAttribute("data-"+name);
instance.parentNode.insertBefore(wrapper, instance);
wrapper.appendChild(instance);
}
for ( var i in elements ) if ( elements.hasOwnProperty(i) ) {
var instance = elements[i];
wrap( instance, instance.getAttribute("data-"+name) );
}
}
// check for iOS 12 before adding the enhancement ( iPhone )
var iOS = /iP(hone|od|ad)/.test(navigator.userAgent) && !window.MSStream;
if ( iOS ) {
var version = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/);
version = parseInt(version[1], 10);
if ( version >= 12 ) {
addEnhancement();
$('.ar-badge').css("display","block");
}
}
// check for Android 9 ( pie ) and above ( Android )
var android = /android/i.test(navigator.userAgent);
// console.log(android);
if ( android ) {
// if ( false ) {
if (parseInt(getAndroidVersion(), 10) >= 9) {
$('.android-ar-badge').css("display","block");
}
}
function getAndroidVersion(ua) {
ua = (ua || navigator.userAgent).toLowerCase();
var match = ua.match(/android\s([0-9\.]*)/i);
return match ? match[1] : undefined;
};
}
enhanceWithARQuickLook();
</script>
Note:
- It works only above the IOS 12 operating system and for android its works above 9(pie). For more info for supported device please visit Google developers.

Adding required files through <Script> in tag or before </body> tag. You can add it through the Local Path of your folder or Via CDN Path.
- Three.min.js
- GLTFLoader.js
- Classie.js
- Orbitcontrols.js
Refer the below-attached screenshot for required changes and adding parameters in Script
- Create environment, Texture files, and Export 3D model from design tools ( i.e. MAYA, Blender, etc… )
- Do changes if required in parameters for changing model position for displaying on front end.
- Eg. HTML & CSS
Export Files glb/gltf (Android) and usdz (iphone) From Design Tools
- Creating 3D model from any software like (Blender/Maya) and export files glb/gltf File ( supported in android devices ) and also abc file ( supported in iPhone Devices )
- Afterward, convert abc file from usdz file and apple developers.
Demo Link
- Demo
- Also open in mobile for best AR experience
Tools and Technologies Used
- HTML/CSS
- Maya/Blender (Creating 3D Model)
Conclusion
I hope that this blog might be useful to you. We will shortly come up with an update about “How to Integrate Web AR Model In WordPress” on the same channel, so stay in touch.
NOTE:
If the model does not work in the Local Server or Test Server. Please upload and run it on a live server.
