Hi,

I'm currently using threex.webar on a project. It's working fine, so thank you very much, it makes using Aruco with Three.js a lot easier.

Right now, I'm trying to make a projection (markerObject3D) based on a marker, but I want it to be next to the marker, not on it.

Here's how I achieved that, using Three.js translatex() :

function render() {

    translateMarker3D(markerObject3D);
        movieMaterial.update();
        backgroundTexture.update();
        effect.render(scene, camera)
}
function translateMarker3D(marker3D) {
       marker3D.translateX( 80 );
}  

The thing is : it kinda work. It flickers a lot, when it's great without transition.

I also tried to change aruco's returning values (in threex.jsarucomarker.js):

object3d.position.x = translation[0];

But it renders the same, flickering.

So my question is: what is the best way to make a projection next to a marker?

hello again, thanks about the toturial you make now im trying using it :D hehehe, im trying to re-code it. i want the video not to large so i edited the webgrabbing.js so the video looks like below, but after i try it to AR it, the result is like this, the AR is not syncron, what should i do ?

hehehehe :D thanks for your time

yeah one think again :D if its not make a burden to you, where i can contact you if i want to ask about your AR ? just here or there is others place ? hehehehe sorry to make you uncomfortable :D

Chrome has (correctly imho) changed security policy for web camera access etc to only allow it on secure domains: https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-powerful-features-on-insecure-origins

This means that several of your example links fail. Luckily github.io also supports https so you only have to update your links!

Hi,
How to render multi object with multi marker at the same time ?

Reza

MediaStreamTrack.getSources() was removed in Chrome 56,
https://www.chromestatus.com/feature/4765305641369600

the recommended solution is to use MediaDevices.enumerateDevices() instead.

hej. good job! congratulation.

I try to use it with stl loader together. with success.

I wonder how to display multiplied 3D objects when I put many cards with markers in camera view.
I thought this code will do so but it does not:

var markers = jsArucoMarker.detectMarkers(domElement);
markers.forEach(function(marker){
jsArucoMarker.markerToObject3D(marker, markerObject3D);
}

I see correct numbers of markers recognized by value: markers.length
for example 3 or 4, but only the one displays 3D stl object, the one closer to camera.

any idea?

Question: Seeing as how cordova-based hybrid and cross-platform applications expose system functionality but still utilize web technologies - could this library be tuned to work with iOS as well as Android based platforms via a cordova setup? There are even cordova-based plugins such as this one that expose the full WebRTC JS APIs for iOS. I'm wondering if your library could be made to work in this sort of scenario - and I would love helping in anyway I can to provide an extension for this library if necessary. Thanks!

Hey,
I'm a relative noob at this stuff and i couldn't get it to work but maybe you know how.

I'm trying to use the default threejs post processing and composer things, but i just cant get them to work together with threex.webar

how would you go about it?
thanks in advance

Hi,

I thought it would be worth adding a serial image grabber to your code.

That will allow to easily use most of IP-cameras.

Even a smartphone can be turned into an IP-camera with "IP Webcam" app, https://play.google.com/store/apps/details?id=com.pas.webcam&hl=en

I made an example implementation https://github.com/Bangybug/threex.webar/blob/master/threex.imageserialgrabbing.js in my forked repo https://github.com/Bangybug/threex.webar
