  2. Outline • Introduction • User interface • 3D modeling operations • Operations on the 2D pattern view • Implementation • Physical simulation • 3D modeling • Results • Limitations and future work

  3. Introduction(Ⅰ) • Characters • Runs simulation concurrently with modeling. • Incorporates physical simulation into an interactive design process. • Combines a sketching interface and integrated physical simulation.

  4. Introduction(Ⅱ) • Related work • Shatz et al. [2006] • Mitani and Suzuki[2004] • Julius et al. [2005] • Mori and Igarashi’s [2006]

  5. Introduction(Ⅲ)

  6. User Interface

  7. 3D modeling operations (Ⅰ) • Creating a new model • Cut • Creation of a part • Pull • Insertion and deletion of seam lines

  8. 3D modeling operations (Ⅱ) • Creation of a part • Pull

  9. 3D modeling operations (Ⅲ) • Insertion and deletion of seam lines

  10. Operations on 2D pattern view

  11. Implementation • Physical simulation • Mimics the effect of internal pressure • Formula : • Figure:

  12. Physical simulation (Ⅰ) • Adjusts each edge length to preserve the integrity of the cloth material • Formula : • Figure :

  13. Physical simulation (Ⅱ) • Formula : • tij :The forces from the neighboring edges (Ei) • lij :represents the rest length of an edge eij • Figure :

  14. 3D modeling (Ⅰ) • Creating anew model : • Generates two-sided mesh • Physical simulation • Updates the 2D mesh • Repeats adjustment process and the physical simulation until convergence Add

  15. 3D modeling (Ⅱ) • Updates the 2D mesh • Laplacian smoothing (c)→(d) • Ni is the one ring neighbor of vi • B is the boundary

  16. 3D modeling (Ⅲ) • Examples in which our algorithm successfully found appropriate 2D patches that yielded the desired 3D shapes

  17. 3D modeling (Ⅳ) • Cut : • The right-hand side of the cutting stroke is removed and a new mesh is created on the cross-section. • Creation of a Part : Add

  18. 3D modeling (Ⅴ) • Pull : • Insertion and Deletion of Seam Lines : • Insertion:Cuts the patch along the added seam line and updates the meshes • Deletion:Merges the patch

  19. Results (Ⅰ)

  20. Results (Ⅱ)

  21. Limitations and future work • Limitations • Future work • Prepare several predefined material parameters and allow the user to choose • Incorporate more domain knowledge into the system

  22. ~The End~

  23. Creating anew model (Ⅰ) • Finding the spine Back

  24. Creating anew model (Ⅱ) • Pruning Back

  25. Cut Back

  26. Creation of a Part (Ⅰ) • Extrusion algorithm

  27. Creation of a Part (Ⅱ) • Sweeping the base ring Back

  28. Future work • More sophisticated, off-line algorithms for texture atlas generation [Milenkovic 1999; Bruno et al. 2002] and cloth simulation [Grinspun et al. 2002; Choi and Ko 2002; Breen et al. 1994] have been studied in textile industry. • It is our future work to explore a way to apply these sophisticated methods to interactive setting.
