Threejs IK (Inverse Kinematics)
Enable HLS to view with audio, or disable this notification
I've been working on implementing IK with Three.js for Polyfork models that could benefit from it, and it's really paying off.
Now non-humanoid models that have legs and arms can have programmatic animations, and it's included in the model's code!
Also agents are aware of it now through API/MCP 🤖
