Trefoil Knot

3D Rotation

Encode: Rot_0, Rot_1, …, Rot_n  

Trefoil Knot

3D Rotation

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.
