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

Infinitesimal deformation

 Finite element model  Here  Modal displacement

Modal rotation We call the modal rotation matrix.

Integration of rotational parts  In case of large deformation  A concept of local coordinate is employed

Modal analysis in local coordinate        

 The decoupled ODEs can be solved numerically using semi-implicit integration:

Constraint  Position constraint  Orientation constraint

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

Orientation constraint  Similar to position constraint

Some results
