Abstract: Provided are a driving method and apparatus of an avatar, a device and a medium. The method includes acquiring the skin weight of each skin vertex associated with the current bone node in the skinned mesh model of the avatar; acquiring target avatar data of the skinned mesh model when a picture to be converted is converted into the avatar; determining the bone driving factor of the skinned mesh model based on the skin weight, basic avatar data of the skinned mesh model and the target avatar data; and driving the skinned mesh model based on a bone driving factor of each bone node.

Abstract: Embodiments of a method, an apparatus, a device and a storage medium for an animation interaction are provided. The method may include: receiving a person image sent by a terminal device; then generating a three-dimensional virtual image based on the person image, where the three-dimensional virtual image is similar to a person in the person image; generating animation interactive information, where the animation interactive information includes a sequence of interactive expression frames; and sending the three-dimensional virtual image and the animation interactive information to the terminal device.
