We won’t forget optimization!!

32. AR with A-Frame
We’ll use AR.js to add AR functionality to the page
3D objects are placed with Markers:

49. AR with WEBXR

50. AR with WEBXR
• All WebXR Demos require:
• Android 8.0+
• Chrome Canary v70-72 (late 2018)
• Flags enabled:
• WebXR Device API
• WebXR Hit Test
• ARCore installed
Protip:
If using WebXR a lot, prevent Canary
from auto-updating in Play Store

51. WEBXR Hit Test

57. Conclusions
• AR on the web is available today with A-Frame
• AR with Hit Points is coming
• AR does not have to be processor intensive, nor utilize huge
amounts of data
