This talk presents DreamWorks’ Feather System Hummingbird, which is used for grooming body feathers and modeling scales interactively in real-time. It is also used for feather motion such as secondary motion or wind, for feather special effects such as ruffling or puffing up, and for feather finaling. The system has been used in several shows at DreamWorks including How to Train Your Dragon 2, Bilby, and How to Train Your Dragon: The Hidden World.
