Been working on integrating WebXR Hit Test module to the Engine.
It allows to raycast representation of the real world geometry by underlying AR system. So applications are various, like: placing objects in your rooms, or pictures on walls. Painting stuff on real world. Basic LIDAR. And more ways to anchor experience to the real world geometry.
Please take a look at PR and let me know your thoughts: https://github.com/playcanvas/engine/pull/1926
Once deployed, this project will be good to test: https://playcanvas.com/project/672464/overview/ar-hit-test
Don’t forget to enable WebXR Hit Test Module in chrome://flags as it is still a draft spec.
And small tweet about it:
