Problem to Address

• I want to create my own plush toys!

3
Problem to Address

• I want to create my own plush toys!
• However, it is difficult for a non-expert to
• design 2D pattern appropriately

4
Goal

• We use a sketching interface for 3D modeling.
• The Plushie system constructs
• appropriate 2D cloth patterns
• 3D physical simulation result

Help a user to design her/his own plush toys.

Physical Simulation

• simple model to mimic stuffing effect.
• First step each vertices are moved in a normal
  direction
• Second step edge-length adjustment

Limitation

• Our 3D pulling operation works for inter-patch
  seams
• But not for intra-patch seams, i.e. darts.

Conclusion and Future work

Conclusion

• We use a sketching interface for 3D modeling.
• The Plushie system constructs
• appropriate 2D cloth patterns
• 3D physical simulation result

Help a user to design her/his own plush toys.
18
Future Work

• prepare several predefined material parameters
  and allow the user to choose the desired setting
  for each target material.
• incorporate more domain knowledge into the system
  so that an inexperienced user can design more
  sophisticated patterns.
• develop an intelligent interface.
