Three-dimensional virtual character intelligent skinning method

Abstract

The invention belongs to the technical field of three-dimensional dynamic graph processing, and particularly relates to a three-dimensional virtual character intelligent skinning method based on deep learning, which particularly comprises the steps: skeleton generation (geometric contraction, edge folding and skeleton optimization) and skinning intelligent prediction (feature extraction, model construction, model training and skinning prediction). According to the method, skeleton generation, binding and skin weight assignment work can be automatically completed only through the grid model of the three-dimensional virtual character, so that a good effect can be achieved when the method is applied to grid models with different complexity degrees, skeleton binding and weight assignment are directly completed for the constructed three-dimensional virtual character, and the method is high in practicability and easy to popularize. When the method is applied to a high-precision three-dimensional model with a huge number of vertexes and patches, the manufacturing time of the skinned skeleton animation can be greatly shortened, the cost can be reduced, the animation manufacturing effect is vivid and natural, and the complexity of three-dimensional animation manufacturing is simplified; and therefore, the method can be applied to the technical field of skinned skeleton animation manufacturing and is wide in prospect.

Description

Technical field:[0001]The present invention belongs to the field of three-dimensional dynamic graphics processing, and more particularly to a three-dimensional virtual role intelligent skin method based on deep learning.Background technique:[0002]The production of three-dimensional animation is mainly using computer graphics methods, visually realizes the effect of motion in three-dimensional space. Skeletal skinning method is currently using the most three-dimensional animation methods, the three-dimensional model of this method includes both bones and skin: the bone is the skeletal hierarchy tree structure, with a skeleton and multiple root skeleton; The skin is controlled by each vertex of the three-dimensional model, and its controlled bone affects the weight. The skeletal skin method is simple, and the effect is excellent: the skin of the entire three-dimensional model is a whole, under the control of the bone control, calculate the vertex position of different motion gestures ...

AI Technical Summary

Problems solved by technology

In the process of skinning the 3D virtual character, it is necessary to manually complete the bone binding. To achieve a more realistic and natural action effect, it relies heavily on the experience of the designer, requires a lot of manual assistance, and repeatedly adjusts the skin Weight, continuous optimization, heavy workload
