Skeletal skin animation realization method and device

Abstract

The invention provides a skeletal skin animation realization method and device. The skeletal skin animation realization method comprises the steps of building a skeletal model of a target object, andsetting at least two bones in the skeletal model; configuring a vertex weight table for each root skeleton to obtain at least two vertex weight tables, the vertex weight table of each root skeleton comprising vertex information of vertexes in a skin network corresponding to the skeletal model, and each vertex information comprising vertex identifiers of the vertexes and influence weights of the root skeletons on the vertexes; acquiring skeletal animation data stored in the model file of the target object, and determining an actual position of each vertex in the skin network in a world coordinate system based on the skeletal animation data and the at least two vertex weight tables; and rendering the target object based on the actual position of each vertex in the skin network in the world coordinate system to obtain a skeletal skin animation of the target object. Therefore, the actions of different parts of the target object can be flexibly adjusted.

Description

technical field [0001] This specification relates to the field of Internet technology, and in particular to a method, device, computing device and storage medium for realizing skeletal skin animation. Background technique [0002] The basic principle of skeletal skin animation is to calculate the vertices of the skin network through the vertex hybrid dynamic algorithm under the control of the bones, and the child bones move relative to the root bone, and are driven by animation keyframe data. [0003] In the prior art, a skeletal model includes a root bone corresponding to a skeletal skin animation, and the skeletal skin animation corresponds to an action of a target object. If you need to make a skeleton skin animation of the target object flying in the air, and the target object has a small movement in the hand during the flight, you need to make two skeleton skin animations, one is the overall state of the target object during the flight Animation, the other is the anima...

Problems solved by technology

[0004] However, in the above method, as many animations as there are actions of a target object, it not only wastes computing resources, but also takes up memory space, and it is difficult to flexibly adjust the actions of the target object, so a simpler and more convenient method is needed Realize skeletal skinning animation
