KinEtre allows novice users to scan arbitrary physical objects and bring them to life in seconds. The fully interactive system allows diverse static meshes to be animated using the entire human body. Traditionally, the process of mesh animation is laborious and requires domain expertise, with rigging specified manually by an artist when designing the character. KinEtre makes creating animations a more playful activity, conducted by novice users interactively at runtime. We enable users to animate meshes of varying shapes and sizes, including non-humanoid meshes and incomplete surfaces produced by 3D scanning.
