Camera Zoom / Magnifying Glass

[David_Oldham]

Hi, I was wondering if a camera zoom function would be possible to allow for example a user to zoom in on details of an image target without having to get so close that tracking is lost? Effectively like a magnifying glass.

Thanks for contacting 8th Wall.

There is not a way to zoom the camera feed at this time, but I’ve logged this as a feature request and will raise this use-case to our product team.

For best image target tracking from further distances please reference this thread:

How to maintain tracking of image target from farther distances

I’m working on a project with uses several image targets to maintain tracking of a single object. I was wondering if there were guidelines or tricks to use to maximize the distance I can travel away from a single image target before the xrimagelost event is triggered. I’m currently using some random images as targets that meet the recommendations of this page but I’m still only able to get a few feet away from the printed images.

There is a scale attribute, through Three.js, that you can use for your custom a-frame entities.

this.el.object3D.scale.set(xScale, yScale, zScale);
