    Hello all, I think i identified a bug: I have a suspicion that the scaling of the model creates a wobble or shaking model. if the scaling remains small (1 1 1), the wobble stops. presumably it is still there, but due to the small scaling it is no longer visually perceptible. Changing the smoothing values does not change anything. Try my example: https://vision.evij.de/ar-test/ use hiro marker: https://raw.githubusercontent.com/AR-js-org/AR.js/master/data/images/hiro.png

    I think that White background markers are not working, i've tried the exemple .html in the official repository and the console.log shows THREEx.ArToolkitContext: 'labelingMode' is not a property of this material.
    and there is no marker detection

    I've read through some comments and apparently a lot of people are experiencing issues with Location Based AR.

    Is this stable enough to be used in a project?

    I tried using the library and the results were pretty bad. Objects weren't near the specific GPS point and they also followed me if I tried walking away from it. Also tried setting up some specific parameters regarding min/maxDistance, GPS update settings and also smoothing factor but nothing worked well.

    Has someone actually got a satisfactory result with this or should I just give up and develop an app instead?

    Hello Everyone,
    I am building an AR.js App with around 100 Markers. I am using custom Image Markers with different border colours (Not NFT Images) and the thing that I noticed is, that my camera starts detecting objects (such as my keyboard, books and posters in my room) that are not Markers that I am using in the App. Is there anyway that I can improve the camera detection quality or block the camera to detect objects in real world that are not markers. There are some properties that I modified, e.g. Marker size, SmoothCount, SmoothTolerance, SmoothThreshold but without help so does anybody have a tip for me?

    Hi everyone, i have an issue with location based AR. the issue is that with the 'click places' code i can only click and see info of places that are as far as 1km away from (i have seen 400, 600, 890 meters). More than 1km (1000meters) places cannot be clicked. I've tried making the scale bigger but with no result. Anyone knows what could be wrong? Thanks!

    Hi - I have some code that does its own camera tracking meaning I have corner points of a square marker in 2D screen co-ordinates... is there any way to create a custom marker type that can inject this, rather than relying on AR.js to do the tracking?
    antoniskamzel
    @antoniskamzel
    Seems that places more than 1km away from the phone won't show up despite having far value more than 1000 meters. It worked with the same code until 2 days before. I didnt change anything in my code and suddenly it doesn't work. Some places that are about 1km away will show when having them in the center of the screen and won't show if they are at the edges... What could be wrong?

    It works great with android phones.
    but the video don't start autoplay with iphones.
    but my project requires cross platform mobile devices.
    I know this is a very old issue but i couldn't find any proper documentation how this can be fixed.
    Can anyone provide me a complete solution to fix this autoplay issue with iphone?

    Hi everyone, I am new here. I'm Dante in Chicago IL USA. I have a few questions related to a project I am working on. I also have an excellent sample of what I am trying to do displayed in a 2-minute video (not mine) that can easily summarize my needs by scrolling quickly through the video in less than 2-minutes. So my first question is can I display a 3D rendering of new building (unbuilt) on a vacant plot of land to display how that building would look if built on the parcel of land and then walk around all sides of that building to show viewers how it would look? Here is an example: https://renderinghouse.com/augmented-reality/ Scroll down to the very bottom of the page and watch the 2-minute video of the "See Our Future Office On-site With Augmented Reality" I want to know if I can do this with AR.js? I would appreciate anyone's help in answering the question(s). Thanks in advance!

    Hello everyone! I am experimenting with Location AR in 8th wall. I have already gotten several solutions from 8th wall support, but nothing works. They had asked me to post this here because they know too little about this topic and you guys can probably help me.

    I had first created a completely new project in 8th wall and saw that the method works well. Now I wanted to add the same method in my existing project but this is where it does a bit difficult....

    I am just adding these lines of code:
    Head.html:

    • <script src=“https://raw.githack.com/AR-js-org/AR.js/master/aframe/build/aframe-ar-nft.js” crossorigin=“anonymous”></script>
      Body.html:
    • <a-scene ... vr-mode-ui=“enabled: false” embedded arjs=“sourceType: webcam; debugUIEnabled: false;“> ...
    • <a-camera .... gps-camera>....
    • <a-entity ..... gps-entity-place=“latitude: 50.92030355222422; longitude: 2.97459464787214;“>

    On the first video you can see how it works normally without these 4 lines of code (not location-based) and on the second video I add these lines and immediately have a zoomed in video. You can also see that the splash-image (start screen with start button) is even struggling by using that gps camera. Hopefully this is enough information to help me :)

    Video 1 (normal): https://www.dropbox.com/s/sxm02wey5fu8x8c/RPReplay_Final1648130782.mp4?dl=0

    hello there all!
    I'm a designer using ar.js for a thesis project, and having issues with A-Frame location-based AR. Every entity I've placed has a specific gps-entity-place with lat and long coordinates, but when I open the project on my phone the distance doesn't adjust as I walk closer or further away. Every entity treats the phone as the origin, not specific physical-world locations. I'd like to not have to import the locations through an API, because there's only a few of them, but if it comes to that I will.

    I think @SandroMiccoli brought up a similar issue a couple of months ago, wondering if anyone following the new location updates has any insight.

    So I come from using SecondLife and being able to manipulate the face of an object to have a texture is my goal... I have an Image Based Example setup with ar.js and have a 3D Model that is basically just a blank Frame with no image on the inside. The Model has 3 Faces Defined in Blender, is it possible to modify the a-entity in a way to dynamically change out the color and texture of those three faces? Or will we need to do some 3JS magic then use the final product of that?

    Hello, I'm developing several AR.js interactives for a project and am using the gesture support library. I found an a-frame/three.js rendering problem with z-buffering for adjacent and transparent objects and see that the problem seems to be resolved if I use the latest a-frame, 1.4 version. Is using the latest a-frame version compatible fully with ar.js and the gesture support lib?

    Hi everyone, im trying to implement marker based AR to my three.js project and im having some problems. I have a normal threejs scene with multiple splines and AR mode can be enabled via a GUI button. When i enable AR, the object is way too big (i can scale it though) but the main problem is that it does not stay on a locked position on the Marker but kinda moves with the camera and gets distorted when i increase the resolution of ARjs. Does anyone have some ideas where i can start to fix it? Thanks in advance and have a good day :)

    Hi there! We're trying to use AR.js for a uni project, but have run into a little issue. Ideally, we want to use a piece of paper with three different trackers, and interpolate between them to place an object in the middle. This should probably be relatively straightforward, but I can't find anything about this in the documentation :)

    We did find a working demo using jsartoolkit5, so the underlying tracking library of AR.js does support this functionality

    Hello! I have been working on an AR sample for a client- It works fine locally but I get an 404 worker error on my server. After doing some research I have found this AR-js-org/AR.js#249 mentioning it was a cors error. But all of my files are local to the project, I am not pulling any resources from external sites- So I should not be receiving a CORS error should I? I have supplied a glitch which provides the index and shows the paths, I just am not provide the image or videos since they are client material. Glitch Link
    Brent Williams
    @DDincBrent
    So I updated the glitch link with non confidential NFTdata and a non confidential video, and all of a sudden it works on glitch? So could my issue with it not working on my server be because I am trying to use local files to the project instead of files hosted somewhere else?

    Hello everyone !!!!
    I am currently working on a aframe project and want to enhance UX.
    I am wondering if anyone has created a custom marker reader that enables users to focus their camera on the marker that is supposed to be scanned? Like https://minhazav.medium.com/qr-code-scanner-using-html-and-javascript-3895a0c110cd but for a-marker specifically?
    Looking forward for your help and support !

    Hello everyone
    I'm trying to change an attribute with the value of a variable. Previously I have already defined the id of the a-asset-item where these are HEXANO-obj and HEXANO-mtl.
    I tried it this way but got no result.

    <script>
    function change(){
    var nombreQuimico = "HEXANO";
    var objeto = "#" + nombreQuimico + "-obj";
    var textura = "#" + nombreQuimico + "-mtl";

    //Change attribute obj and mtl from a obj model
    var el = document.querySelector("#entityID1");
    el.setAttribute("obj-model", "obj:objeto; mtl:textura");
    }
    </script>
    Can you help me? Thanks!

    @rafelis1997
    @mabustillo14 you're trying to pass a variable inside a string, to do this on javascript you need to do it this way el.setAttribute("obj-model", ´obj:${objeto}; mtl:${textura}´);
    @cartagenajones:matrix.org you have to start your experience on full screen, then you can create a div wich will display the image over the a-scene with display:absolute and z-index:1000

I'm looking for some examples of displaying a map in AR (like this https://www.maptiler.com/news/2018/11/maps-in-augmented-reality-with-javascript/). I can only find old examples that are deprecated now. Could anyone help?
