Hi, I am trying to create an AR app for a model. I want to enable the Resize option in AR mode. I tried with puzzle drag scale at various levels but could not get the required output. I have included the image of puzzles that I have created to enable drag scale. Please correct me if I am wrong in placing the puzzles. The drag scale works before entering AR mode, but after entering AR mode it doesn’t.

It really points out the difference between the 3D web page experience and the AR experience. I think that we, as 3D developers, have to think carefully about the AR experience that we build for our users.
When I use Verge3D on a web page, I can pan and zoom the scene. I can do this with touch or with a mouse. In this case, panning and zooming are moving the virtual camera. This user interaction does not change the size of the 3D object(s).
When I use Verge 3D in AR, I can pan and zoom the 3d scene by moving the phone or tablet that I and using to view the AR world. In my experience, Google AR services do a good job placing the 3D geometry into the real world at the scale at which they were drawn. For example, if were to draw a 1-meter cube in Blender, the AR system renders the cube at a scale that makes it appear to be 1-meter.
In the AR scenario, should we allow pinch-to-zoom? If we did, the pinch-to-zoom would be changing the scale of the 3D meshes. This is a different behavior that pinch-to-zoom in a webpage (where this gesture is interpreted as a dolly camera move). Maybe the answer is to build on-screen tap (not drag) controls that only appear in AR mode that explicitly affect the object scale?
These are just some ideas. This is not a criticism of the Verge3D system. AR is new and I think that we need to work on the user experience and establish some best practices. I am curious to see what solutions other users have tied to implement.

Hi,
we had to postpone the implementation of AR pointer events since the WebXR AR specification is not implemented fully in the Chrome browser yet. Once they are available, we’ll make them accessible through puzzles. -
