Study On The System Of Human Motion Simulation In The Fluid Environment

At present, Three-dimensional computer animation is the focus of computer research. The technology of human motion simulation is applied to various fields. Focus of this study is to achieve simulation system of human motion in the fluid environment, due to limitations of hardware conditions, real-time simulation system still is a difficult research in domestic and international. The purpose of this thesis is to ensure the authenticity of the simulation results, and try to improve the simulation efficiency. If the simulation inefficient, we may be appropriate to reduce the accuracy of the simulation so as to improve the simulation performance.Based on the hinge body animation, this thesis build human motion simulation model, and achieve the process of human interaction with the fluid, and control of human movement in the fluid environment. Structural of model of the human is tree, between father-chain and son-chain meet chain relationships, we control the movement of the relationship between sub-chains through simulation system. In this thesis, a method based on the coupling surface to study the interaction with the human body fluids. We get the target path of human motion through three-dimensional algorithm of A-Star,and we study in the path of movement of the body fluid environment according to the change in the set state and the corresponding algorithm.In this thesis, the improves on conventional methods mainly reflect in three aspects: this thesis improves the passing algorithm of the coupling faces, making the performance of the interactive simulation is improved. This thesis improves the calculation formula of acceleration, making the speed more smoothly.This thesis improves the routing algorithm of human body is improved, making the body’s state of motion has more diverse and better simulation results.Because of the great number of coupling surfaces, the higher the complexity of matrix calculation, we proposing a method based on sampling, and reducing the number of transfer coupling surface, The residual coupling surface interpolate. Further, considering the viscous resistance of the fluid, we improving the formula for calculating speed and improving linear formula is non-linear formula. Further, the convergence of the formula has been proven. The algorithm of the motion path of the human body is improved. Selection algorithm is proposed based on the visual space, makes the body’s state of motion has more diverse and better simulation results.Finally, the achieving and test of the simulation of the overall system is introduced, and elaborating some of the key modules and implement interfaces. Focus on two parts of the simulation system and rendering system.Subsequently, we summarize the research results and looks to further work.
