Presentation Transcript

  1. Applications of a Motion Capturing System: Music, Modeling, and Animation • Chase Finch, Kevin Musselman, Bill Mummert • College of Engineering and Science, Clemson University

  2. Motion Capture • History • Vicon 8 Motion Capturing System • Motion Capture in Animation • Motion Capture in Modeling • Motion Capturing in Adio/Visual Interactions • Observations • Conclusions

  3. Brief History of Motion Capture • 1980-83 Simon Fraser University’s biomechanics labs start using to computers to analyze human motion • MIT started using optical tracking systesm Op-Eye and SelSpot • “Mike the Talking Head” of Silicon Graphics

  4. Vicon 8 Motion Capturing System • Passive System • 8 infared cameras tracks “markers” • Records cartesian coordinates (x,y,z) • Average recording rate of 120 fps • Newer system has 12 cameras and records at 484 fps A visual representation of MoCap

  5. Motion Capture & Animation • Maps collected data to a virtual character • Requires creating a “rig” • System of structures in a model with control points to move the model • Facial motion capture

  6. Motion Capturing in Modeling • Using motion capture data to create rigs and models • USC derives human skeletal models from volume data

  7. Motion Capturing Audio/Visual Interactions • Sound creation usually requires a physical motion ie drawing a bow across a violin requires a precise motion for certain sounds • Motion Capture Music • Outputs mapped commands to a MIDI creator • Dance Instruction • References • David J.
