Encode:Use Quaternions
More Aggressive Moves
• Not just rigid body motion
• Deform shape
• Preserve crucial characteristics

Compression vs Decompression
• Compression, Phase I.
• Decompression, Phase II.
• Phase IB Project with Kerner Technologies??
Portability for Display
• Ipod to Big Screen by parameters.
• 3D TV. (Prototype in San Rafael.)
TEA Authoring Tools for DVFX
• Time-checker like spell-checker – runs in background; not intrusive!
– very expensive if missed.
• Parametric re-design; similar to CAGD PTC
• Integrate with VFX.
Conclusions
• Time can be modeled continuously while frames remain discrete.
• Difference between
– Perturb then approximate versus
– Approximate then perturb.
Quotes & Interpretation
• “You can’t rush art.”, Woody, Toy Story 2
• “Time is money”.
• Correct math to make the most money.
