The Khronos 3D Formats Working Group is constantly assessing emerging requirements of the glTF ecosystem and asking how the group can make the most impactful progress. Over the past 18 months, one issue has consistently bubbled to the top of these discussions: interactivity.
The urgency of developing new interactivity and behaviors capabilities for glTF has been fueled in part by the evolution towards the open metaverse. It’s clear that glTF can and should have an important role to play in this ecosystem, but we have some important functionality gaps to close first. We’ve spent the past few months cooperatively refining proposals for how we might build interactivity into glTF 3D assets. This blog will outline our current approach and reasoning, as well as invite the community to weigh in.
