Presentation Transcript

  1. Real Time Simulation of Large Rotational Deformation Authors: Min Gyu Choi and Hyeong-Seok Ko Presented by Yin Yang

  2. Infinitesimal deformation

  3. Infinitesimal deformation

  4. Infinitesimal deformation

  5. Modal displacement • Finite element model Here

  6. Modal rotation We call the modal rotation matrix.

  7. Integration of rotational parts • In case of large deformation • A concept of local coordinate is employed

  8. Modal analysis in local coordinate

  9. Modal analysis in local coordinate • The decoupled ODEs can be solved numerically using semi-implicit integration:

  10. Constraint • Position constraint • Orientation constraint

  11. Position constraint • Let λ be the number of constrained points • Forces do not have to be applied on the constrained points

  12. Orientation constraint • Similar to position constraint

  13. Some results

  14. Some results

  15. Thank you and Question?
