I am currently working on the free and open-source **VTuber** software [Brioche Puppet](https://github.com/HanetakaChou/Brioche-Puppet).
As a rendering engineer, the **rendering** is implemented by me. But the third-party libraries [BulletPhysics](https://github.com/HanetakaChou/BulletPhysics) and [MeidaPipe](https://github.com/HanetakaChou/mediapipe) are used for **ragdoll physics** and **motion capture**.
