Skinning method and device for virtual characters and electronic equipment

Abstract

The invention discloses a skinning method and device for virtual characters and electronic equipment The method comprises the steps of loading a three-dimensional model of a virtual character and skeleton data corresponding to the virtual character, wherein the three-dimensional model corresponds to grid data of a plurality of vertexes of the virtual character, and the skeleton data corresponds todata of a plurality of joint points; determining vertex characteristics of each vertex in the grid data and distance characteristics from each vertex in the bone data to each joint point; fitting vertex features and distance features to obtain binding features of all vertexes of the virtual character, the binding features being used for determining binding weights of all joint points and the vertexes; and performing skinning operation on the virtual character by using the binding weight, and binding the three-dimensional model to the skeleton of the virtual character.

Description

technical field [0001] The present invention relates to the technical field related to games, in particular, to a method and device for skinning a virtual character, and electronic equipment. Background technique [0002] In related technologies, for game development, creating game characters is an important process. In game character creation, 3D model animation plays a very important role. The basic principle is to let the position of each vertex in the model evolve over time. Change, in 3D model animation, involves a branching path that is skeletal skinning animation. As the name suggests, skeletal skinning animation consists of two parts: bone and skin. Usually, in the process of creating an animated character, an animation artist first creates a model, that is, creates a character model, then adds bones to the model and makes bone animations, and finally binds the character model to the bones. In this way, when the bone level After the change, the new model grid verte...
