The API is a project module to enable in the studio
You must host those 2 files and let us know their web address so we can set them up in our internal system.
You can register and listen to particular events such as when the experience starts, or when an image marker is found/lost.
You can also setup your own events with the XR+ studio action editor. By doing so you can setup an action on a composition item to call a function you have defined in your script.
Let us know on which project you would like to activate the API module and the url of the .js and .css you need to load in the <body> of the experience.

Interactions are made with the ‘interactions’ module, by switching between ‘states’ of the composition.
A state is made of actions, buttons can be added to it.
When a project switches to a new state, all actions from the state are applied.
There are many different actions, such as:
hide / show an object, play an animation, play a sound effect, change a color or set a timer to switch to another state after a fixed amount of time.
Buttons can be used to switch between states, or trigger an action (play sound effects, start a phone call, display a pop-up with text & image, open a webpage… )
To add a button to a state, first create a button, then add it to one or multiple states
You can follow this step by step tutorial to practice using the states interactions module

With this Screen you can find all statistics about views and interactions with your project in Statistics.
The First Row is displaying the views by date. You can know if it’s on AR, VR or embed mode views.
The Total Actions section tells you about specific data for your experience: time, sessions and the average sessions time.
Action & events column is for interactions with events and possible interactions in your experience like taking a photo, switching to a state, scan an image tracking marker.
The cities sections is for where your experiences were viewed geographically, and the number of views filtered by cities.
All this data can be filtered, by year, by month or by date interval.
To remove XR.+ branding visual elements, check this list (business plan only):
In your project:
In your AR player:
Business users can load projects inside an external web domain within an iframe, like when adding a Youtube video player on a web page.
We provide a template to do so, no coding to do, just upload the .html file to your server.
Note: an SSL certificate (https:// …) on your web domain is required to embed projects.
It is very important to optimize your projects!
Try to keep your project total size (images + models + audio files + video files) under 10Mb, or even 5Mb.
On your 3D models, do not use oversized textures, and delete all faces that are hidden.
Short loading times and a smooth framerate always make an experience more pleasant for the end user…
Above the 3D composition view, you can see an estimation of the time required to load your project, considering the mobile network speed.
Use as less assets as possible, import them once in the assets library and add them multiple times on the composition.
Don't import oversized images.
Reduce the number of polygons in your favorite 3D modeling software, reduce the size of each texture
When you share an XR+ web AR project on social medias or messaging application, a preview of the experience is displayed, here’s an example with a tweet:
The data pulled to populate tweets or other social media shared experiences consist of:
The image used is your project cover, so make sure it’s looking great!
The title and the description can be edited in the studio in ‘Publish settings’ > ‘Project meta data’.

Here’s a simple tutorial on how to publish a 3D model in augmented reality on the web ( aka webAR ).
Let’s go through the various steps on the xr.plus platform…
If you don’t have yet an xr.plus account, create one ( the basic plan is free )
Click here to create a free account
Create a new project and import a 3D model from your hard drive. Supported formats are .obj, .fbx and .glb (gltf).
For this tutorial, I’m using a Bonsai tree available here (download the fbx version).
This model was made by Scopia Visual Interfaces Systems, s.l. and Eteks,
available under the Creative Commons license ( https://resources.blogscopia.com/license-2/ ).
Is it also possible to make a project only from images, but I’ll only cover the 3D model process in this tutorial.
If the imported model includes materials, you will be asked if you wish to import them.
For this model I’m choosing ‘yes’, so materials will be automatically assigned to the meshes.
This is the 3D composition view:
– on the left column you can see the list of all items dropped in the composition (here there is only the bonsai tree)
– on the left column you can also switch the pages, materials and lights listing.
– the right hand side column displays the list of meshes from the model. This is where you can assign materials to meshes of your model
The top material is used on the tree pot, I’m choosing a dark gray for its color
Adding the texture for the trunk (included with the model zip file), on the ‘bark’ material
Adding textures for the soil and leaves. Note that the leaves texture includes transparency.
Some extra material adjustments to darken a bit more the pot and the trunk (changing the default white color of a material to a darker color will also affect the texture), and lowering the shininess of the trunk.
Finally, set the tracking mode to SLAM
Your project is now ready and already published!
On the left column, you can see the public link to your project, in this case: https://xr.plus/2m5
You can customize the project cover image, to do so, go to ‘Publish settings’ > ‘Project cover’.
You can select an image for the cover background and adjust the position and size of the Bonzai tree.
You can import an image from your hard drive to be used as a cover.
Press ‘save cover’ to save your cover.
Let’s have a simple step by step tutorial on making a web AR scene from images.
This tutorial is about making a composition from images, if you’re looking for the 3D model tutorial, go here
If you don’t have yet an xr.plus account, create one

We are going create a simple composition that will look like this when finished.
You can download all the images used in this composition here: tutorial-composition.zip. Of course you can also use your own images.
in the XR+ editor, create a new project.
Click “import a file”. and import the image ‘bg gradient.png’, then click on “add to composition”.
Next, reopen the library and import the ‘octogon.png’ image and add it to the composition.
There’s a gray area all around the white octogon, let’s hide it.
To do so, we need to set the transparency of this image, so only the white shape is visible.
Turn on ‘color keying’, and as a key color, choose the same gray as the one around the white shape.
Now that the transparency is setup, scale down a bit the element on the composition and place it to a bit on the left. You can use the rotation tool to give it a nice little angle.
Open the library to add it one more time to the composition and place it in the center, then add it one last time and place it a bit to the right.
Now import the ‘creature.png’ image, This image is a transparent png, so no need to set a key color.
Add it to the composition, scale it down a bit, and move it a bit in front and a bit down.
One by one, import the 4 screenshots images and place them at the back of the composition.
Import the ‘Little XR’ logo and place it on the top left area of the composition.
Finally, import the ‘play-now.png’ image, add it to the composition, and set its shape to circle, to make a nice rounded shape.
Let’s bring attention to this button by adding a pulse animation. Note that the animation is not visible on the editor, but only when viewing the scene on your phone or in the simulator.
Let’s add an interaction
Click on “set an action”, to open the action editor. Choose ‘open webpage’, set https://littlexr.co as the web address. When users will touch the button, they will be redirected the his web address.
Almost done, now in the ‘publish settings‘ tab, choose a cover background, press the ‘save cover’ button.
Above the QR code, you can see the public link to you scene, in this case: https://xr.plus/lkf (yours will be different).
Type this web address on your phone web browser or scan the QR code in the editor to view the project in web augmented reality.
