Research And Implementation Of Technologies Of Joint Animation

Joint animation technology is an important branch of animation, and it is also an important basis for skeletal animation in three-dimensional animation. Focus on the performance of joint animation joint chain with the animation of objects, such as robots, cranes, insects and the human body and it has the distinctive structure of the joint chain. How to simplify the joint chain structure, and control joint movement, is an important part of joint animation. As an important part of the continuous development of joint animation technology , it has been able to simulate the motion of rigid body or a body, but how to control the chain or the human skeleton joint rigid body natural, accurate, real-time sports, there is a need for further depth study.This two-part study on the joint animation techniques ,first of all, Joint chain structure using the hierarchical structure of thinking ,it can be analyzed the structure of the joint chain of thought on the hierarchy, hierarchical approach proposed two joint chains. The first method is to use decentralized thinking, hierarchical link structure will be divided into a number of joint structures by sub-level joint chain, using methods for each sub-level DH-chain structure calculated the joint point of each bar and chain State. The second method, using the relationships between key points, design a joint package to simplify the hierarchical structure of the link structure. In the optimization of the joint chain, after study of its motion control technology, in solving the state bar of each chain, using the improved Newton algorithm is evaluated.Human body model is a very typical structure of the joint chain, but its structure is much more complicated than the general objects. Similarly, the first of the chain structure of human joint research framework is proposed based on extracted human anatomy human skeleton. Among the many human control technology is proposed based on inverse kinematics algorithm for the periodic motion. This algorithm in a simulated human body regular exercise, such as walking, running, etc., can effectively drive real-time human animation.In traditional three-dimensional animation, it required complicated production process and extensive experience in animation. With improving the joint animation technology, we also can improve the traditional animation production system, design a OpenGL based API interface module the animation of joints. This module joint model as long as the input data and animations Data, we can generate joint animation. To facilitate algorithm analysis, this paper tested the module proposed in this paper layered model joint chain, reverse learning algorithms such as periodic motion, obtained visual test results.
