5. Enable Dynamic Interactions
 
 
- Efficient collision/correlation detection
- 
- What method works best? (e.g. Ming Lin's I-COLLIDE API).
- Useful for tools that identify and exploit behaviors of graphical objects
- Already have a block to block msg passing mechanism
 
- Dynamic surface deformation
- 
-  To achieve more efficient graphical updates
 
- Update shared graphic objects (user changes)
