kig / jsartoolkit Goto Github PK

Hi,
I am wondering how there is this JSARToolkit and also JSARToolkit5 by artoolkit.
Looks the me as booth the the same thing, and the name is pretty much the same as well. Kind of confusing.
Are both toolkits the same? Or just different versions? I do not get the difference between the two.
Thanks

how to detect custom marker using this toolkit...
plz help me

Hello,

I want to add a line to the three.js scene,

        var material = new THREE.LineBasicMaterial({
            color: 0x0000ff
        });

        var geometry = new THREE.Geometry();
        geometry.vertices.push(new THREE.Vector3(-10, 0, 0));
        geometry.vertices.push(new THREE.Vector3(0, 10, 0));
        geometry.vertices.push(new THREE.Vector3(10, 0, 0));

        var line = new THREE.Line(geometry, material);

        arController.addEventListener('getMarker', function (ev) {
            console.log('found marker?', ev);
            var marker = ev["data"]["marker"];
            var vertex, pos;
            vertex = marker.vertex;

            var markerRoot = arController.createThreeMarker(marker);
            markerRoot.add(line);
            arScene.scene.add(line);

        });

This scene runs, but i do not see any lines on the screen?

I'm trying to run the multimarker example in Chrome 56 and getting the following console error (before the whole tab locks up):

Hi,

I got an error when I use custom marker. What I did is this:

var encoder = new FLARIdMarkerDataEncoder_RawBit();
var oReq = new XMLHttpRequest();
oReq.onload = function(e) {
var markerCode = new FLARCode(16,16);
markerCode.loadARPatt(oReq.response);

encoder.encode(markerCode,encoder.createDataInstance());
detector = new FLARSingleMarkerDetector(param, markerCode,80);

}
oReq.open("get", "pattern/custom_marker.pat", true);
oReq.send();

And on my render() function:

function render() {
var isDetected = detector.detectMarkerLite(raster,90); // error triggers here
...
}

Uncaught TypeError: Cannot read property 'length' of undefined JSARToolKit.js:137
c JSARToolKit.js:137
ASKlass.detectMarkerLite JSARToolKit.js:12100

I hope someone can help me with this. And thanks in advance.

I been having troubles trying to visualize or print the ID markers. What Software should i use to open them? I`m Using PC.

I am facing problem in detecting markers because of DLAG

D- distance from camera
L- Lighting in the environment
A- Angle of Marker
G- Grey level of the printed marker

Can anyone please suggest How to get over these issues.

Thanks in advance.

hi, im playing with your code, nice stuff :)

im wondering what is magi.js ? your own webgl lib ?

Hello,

I want to use the same marker twice at the same time and place a 3d model on each.
Is it possible to check which of the two markers is moved so I know which model I have to move?
Hava a marker a unique ID or something like this?

I tried other AR Librarys but these dont track markers, they return every frame a new list of detected markers without relation
to the frame(s) before.
Does this JSARToolKit do too?

Hi guys! I would like to know how to overlay a video over the marker...is it possible? or is possible just overlay images and 3D model???

Hi kig!

Found an issue with NyARLabelOverlapChecker.setMaxLabels function, fixed as below:

• this._labels = createArray(i_max_label);
• this._labels = this.createArray(i_max_label);

Best regards!

Hi kig!

When I try to play the test file "AR_simple_webgl.html", I can't find the video file named "tests/output_4.ogg". Could you please supply the link to it?

Thanks!

Hsia

hi kig! when i give my own recorded video as the source in your demos such as test3.html only the zero'th marker gets augmented by a cube . all the other markers are not getting augmented by the cube . could u guide me as to where im going wrong??

regards,

Hi,

I noticed that there are some hardcoded values in the projection matrix and distortion parameters for FLARParam.js. May I know how you derived those values?
