I’m trying to view my chair in AR but the chair is floating so much and sometimes the image is flickering.

I followed the augmented reality example which is more stable so I have no idea why my chair is moving so much in AR.
When I make a slight rolling movement with my phone, it completely loses track.

I used the indicator group from the AR-example to give the chair an initial position but I wonder how:
1. I would be able to rotate the chair in AR.
2. And move the chair in X and Y with two fingers, in AR.

I’m new to Verge and I haven’t found any tutorials about AR, except for the verge3D documentation.

Can someone give an explanation, please?

A more in-depth video tutorial on how to use different functions in AR would be really nice. Thanks

Hi,

The underlying browser technology, WebXR, is currently in the experimental status. Particularly, the drag controls you are thinking about cannot be implemented now.

However, you can add 3d control elements to the scene, parent them to the camera, and use regular when clicked puzzles to rotate/move your object.

As of stability, if you modify the stock Verge3D example by replacing the model in it, will it work as intended?

Hello Yuri,
First of all, I want to thank you for building such an amazing open platform!

I replaced the stock Verge3D example with my model and it is stable to the rolling movement of my phone (I wonder what determines the stability of this behavior)

If I get closer to the object with my phone, the object gets smaller though.
And if I move in X, Y with my phone, the object also moves slightly in that direction.

I understand that WebXR is still in the experimental stage. I can’t wait to see its full potential and I’m looking forward to seeing some nice tutorials about it.

So it still behaves differently with your model? You might check where the origin of your model is located. I think it should be in the ground zero.

Dear Yuri,

The origin of my object is in its center, Z=0.

Apparently, at Scapic they found the trick to manipulate the object in AR with WebXR:
-One finger: move in XY
-Two fingers: rotate

I hope you will soon find the trick for this very vital CPQ feature, because our customers expect this.
