Real-Time Adaptive Catmull-Clark Subdivision in Unity

Back in 2021 while I was at Unity Labs, I worked with Jonathan Dupuy on a method to achieve real-time and adaptive catmull-clark subdivision of meshes on the GPU. The method is described in detail in our subsequent presentation at SIGGRAPH in 2022 here :

During this research and at the request of interested Unity customers, I integrated this work in Unity as an easy to use, plug-and-play package that acts as a simple variant of Unity's MeshRenderer component. I'm happy to say this work has now been open sourced by Unity. The package is available here :

Thanks to Studio Manette for pushing to get this work released publically and using it in their work, and many thanks to Kenneth Vanhoey at Unity for making it happen !
