Method for manufacturing computer skin animation based on high-precision three-dimensional scanning model

Abstract

The invention belongs to the technical field of computer graphics. The invention relates to a three-dimensional model skin animation generation method. The method for manufacturing the computer skin animation based on the high-precision three-dimensional scanning model specifically comprises the steps that firstly, skeleton binding is completed through a digital three-dimensional model skeleton line scanned by a three-dimensional scanner and an action template library of skeletons, skin weights are calculated, model vertex coordinates are updated in real time, and the computer skin animation is completed. According to the method, the three-dimensional model scanned by the high-precision three-dimensional scanner can be processed, the weight of the vertex of the model is calculated throughan algorithm, and compared with manual processing, the workload of model processing is greatly reduced; and only storing texture coordinates, indexes and node weights of the model by utilizing a skinanimation principle, and calculating new vertex data according to the node weights in each frame rendering process. Compared with a frame data merging method and a skeletal animation method, the method has the advantages that the occupied memory space is small, non-rigid vertex deformation is achieved, and the achieved animation effect is more natural.

Description

technical field [0001] The invention belongs to the technical field of computer graphics, and relates to a method for generating a three-dimensional model skin animation, in particular to a method for producing computer skin animation based on a high-precision three-dimensional scanning model. Background technique [0002] With the rapid development of computer animation technology, it is widely used in movies, games, virtual reality and other fields. Especially in online game production. At present, frame data merging method, skeleton animation method and skin animation method are mainly used, among which: [0003] (1) The frame data merging method merges each frame model in the animation into one model, each frame contains vertex position data, and large-scale vertex data needs to be stored, which is simple but has a huge amount of data; [0004] (2) The skeletal animation method introduces the concept of bones, establishes the relationship between the skeleton and the v...
