View Dependent Character Animation
Prem K Kalra
Slide Slide 44
Introduction
Consider the freeze-frame camera rotate shot of Matrix
Want to create a similar effect in an animated shot…
Slide Slide 77
• Obvious approach for any camera moving shot
• The camera-character relationship is very
fundamental to animation
• View dependent animation – animation that
automatically changes in response to changes in
view point

Slide Slide 3535
Other Possibilities
• Stylistic re-use
• Fusing motion capture data and key frame animation
• Synchronized multiple video streams
Slide Slide 3737
Conclusion
• A frame work for view dependent animation
• Multi modal inputs
• Sketches, Video, Mixed
• Semi automatic computer vision techniques
