Augumented reality for pattern cutting #1459

For a shirt project I'm working on I printed a pattern across multiple small pages (I only have a A4 printer) and assembled the paper back into the pattern pieces. This was laborious.

I have a Meta Quest 3 and I am wondering if anyone has used the augmented reality feature of this platform to assist with cutting out a pattern. The idea being:

Layout fabric on the floor.
Enable Meta Quest 3 AR mode.
Calibrate (?)
Project seamly pattern onto fabric.
Outline the pattern directly onto the fabric with chalk.
cut etc...

Does anyone have experience with this that they can share?

Hi @richardhenwood

Since there's only a handful of us devs here on Github, you may get a better response on the Seamly forums - https://forum.seamly.io/ - where I believe some users have used projectors with Seamly patterns.

That being said... we're working on improving the layout, or more specifically creating a "marker" type layout, but until then my suggestion is to export the pieces in Piece mode. What you can do is create a pattern piece the size of your fabric... then (manually) move the other pieces to be within the fabric piece... then export as SVG. Then project the SVG onto the fabric.

Thanks @DSCaskey,

Yes - I found switching to SVG was helpful in processing my pattern. It also seems that projecting an SVG onto a surface (floor) is somewhat straight-forward. I will probably attempt to test my idea and then take my experience to the forum.

I had a few minutes to test this out. This HTML is my starting point. I need to perform an experiment to attempt to quantify spatial distortion but from my initial view the pattern projection looked 'good-enough' to be useful.

        rotation="-90 0 0" 
        width="2" 
        height="2" 
        transparent="true"
        material="shader: flat;">
      </a-plane>

      <a-entity camera look-controls wasd-controls position="0 1.6 0"></a-entity>
      
    </a-scene>
  </body>
</html>

NOTE: There is a strange artifact that floats around. I expect further development to continue somewhere on GitHub for convenience.
