In movie or games, we can easily find animation in the scene. However, making a animation looks real is not a easy job. In this thesis, we focus on the soft and flexible parts of the body. These parts are usually not easy to simulate. For example, when a big stomach man is running, his stomach should shake. But shaking is hard to simulate. So in this thesis we can refine the animation more real. In the thesis we calculated the forces between each frames and propagate the forces to the shaking parts. Then put the new frames into the animation to make the old animation more real.MASTER THESIS 1 ABSTRACT 2 TABLE OF CONTENT 3 FIGURES 6 CHAPTER 1 INTRODUCTION 10 1.1 MOTIVATION 10 1.2 ORGANIZATION 11 CHAPTER 2 RELATED WORK 12 2.1 DEFORMABLE MODELS 12 2.2 VOLUME PRESERVING TECHNIQUE 15 2.3 REAL-TIME DEFORMATION 17 2.4 SKIN DEFORMATION 20 CHAPTER 3 SYSTEM OVERVIEW 22 3.1 USER INTERFACE 24 3.2 FORCES SETTING 24 3.3 POINT SAMPLING 24 3.4 GREEN DEFORMABLE MODEL 24 3.5 ADDING NEW FRAMES 24 CHAPTER 4 FORCE SETTING 25 4.1 USER INTERFACE 25 4.2 COMPUTING KNOWN FORCES 28 4.3 MAKING NEW POINTS 29 4.4 COMPUTING NEW FORCES 30 CHAPTER 5 POINT SAMPLING 35 5.1 SAMPLING POINTS AND BUILD TETRAHEDRAL GRAPH 35 5.2 COMPUTING DISTANCE BETWEEN SURFACE POINTS AND SAMPLING POINTS 38 CHAPTER 6 GREEN DEFORMABLE MODEL 39 6.1 STRAIN AND STRESS FORCES 39 6.2 DAMPING FORCES AND THE TOTAL FORCES 40 6.3 PROPAGATING THE FORCES 41 6.4 ADDING NEW FRAMES 42 CHAPTER 7 RESULTS 44 CHAPTER 8 DISCUSSION AND FUTURE WORK 48 REFERENCES 492381261 bytesapplication/pdfen-US動畫animationotherhttp://ntur.lib.ntu.edu.tw/bitstream/246246/54338/1/ntu-96-R94725032-1.pdf
