2. Alivn/GAME Lab./CSIE/NDHU Motion Capture Assisted Animation: Texturing and Synthesis2 Outline Introduction Framework Results Conclusions and Future Work

3. Alivn/GAME Lab./CSIE/NDHU Motion Capture Assisted Animation: Texturing and Synthesis3 Introduction Create a method that allows an artist low-level control of the motion Combine the strengths of keyframe animation with those of mocap

4. Alivn/GAME Lab./CSIE/NDHU Motion Capture Assisted Animation: Texturing and Synthesis4 Introduction (cont.) “ Sketch ” an animation by keyframing Animate only a few degrees of freedom Set few keyframes “ Enhance ” the result with mocap data Synthesize missing degrees of freedom Texture keyframed degrees of freedom
