Question about Animation Support (VRMA) Timeline

Open yy-dev7 opened this issue 5 months ago • 1 comments

First of all, thank you for creating and maintaining VRMKit! It's been incredibly valuable as the only native iOS/Swift solution for VRM files, and the implementation quality is excellent. I noticed that "Animation support" is listed in the TODO section of the README. With the official release of the VRMA (VRM Animation) format in early 2024, I was wondering if you have any plans or timeline for implementing VRMA support in VRMKit?

Thank you for your question!

I consider VRMA to be one of the features that should be supported. While I believe the file decoding itself can be implemented without taking too much time, the animation playback will likely require more effort, as it would need an implementation similar to Unity’s Humanoid system.

Currently, this library uses SceneKit for rendering, but it will need to be migrated to RealityKit. Since animation playback will need to be implemented in RealityKit, this will likely be scheduled for a later milestone.

I’m currently occupied with other tasks, so I plan to work on this once those have settled. That said, I will be happy to actively review and merge pull requests from others if they contribute this feature.
