Hi,
I have tried the steps here: https://aframe.io/blog/arjs/#personalize-your-ar-content to create own markers. I have been able to generate the .patt file and also included the path. But on scan, nothing happens. Anyone facing the same issue and found a solution?

I have a similar problem with the threejs version. See: #164

Can you provide your .patt file and an image of your marker?

Hi @wimvdc please find the code below and attached is patt file with marker. This isn't working for me !

<!-- include A-Frame obviously -->
<script src="https://aframe.io/releases/0.6.0/aframe.min.js"></script>
<!-- include ar.js for A-Frame -->
<script src="https://jeromeetienne.github.io/AR.js/aframe/build/aframe-ar.js"></script>
<body style='margin : 0px; overflow: hidden;'>
  <a-scene embedded arjs>
	<a-marker-camera type='pattern' patternUrl='kum.patt'>
		<a-box position='0 0 0' material='color: red;'></a-box>
	</a-marker-camera>

@strappvivek Doesn't work with my PR either. Your marker seems quite complicated though and when checking the .patt file, I can't seem to find much resemblance to your marker image.
You should try something simpler (something like the Hiro marker)

Let me try it out with a simpler marker...

Is there a limitation with the type of markers that can be used?

thanks

The level of detail is definitively limited. When you checkout the Hiro as example (image), you can see that the .patt file (see here) has a structure (at the top) where could read 'Hiro' (you need to look really close).
So I would suggest start from the Hiro image but replace Hiro with a simple word or black/white image.

The marker generator resizes the image to 16px x 16px so if you want an idea of how the pattern will look like you can see how strong it is by resizing and see if the pattern has strong anchors to be considered a "strong" anchor.
See below example of how the Hiro Pattern is resized:

Curious: Why does the engine use such a seemingly limited pattern? Other engines seem to prefer to have more details in their markers.

Will it ever be possible to use completely custom markers (photos, shapes) and not being limited with the big black frame, low detail shapes inside and no overlap over the black frame of the marker?

It would be awesome to have more freedom with the marker - to interplay with the actual surfaces. Should I open this as a separate thread?

Hi there, I have the same issues, all works perfect with Hiro marker, but none of my custom markers work, no one of them, it doesn't matter if they have detail, less detail, simple, less simple, etc, etc nothing works except the hiro marker, any tips?

After following steps mentioned in #164, I am still not able to scan custom markers.

Website - https://sadigitaldiaries.com/

I opened above website in mobile and tried to scan below images one by one. Blue box is appearing one marker is hiro. But, it is facing in the case of customer marker (dd).

Markers -
ar

Output -
ar

Kindly assist.

if still interested, try to use a pixeled text on that 'D D' marker. Use pixeled font.
