SUMMARY:MGPBD: A Multigrid Accelerated Global XPBD Solver
DESCRIPTION:Chunlei Li and Peng Yu (Beihang University); Tiantian Liu (Tai
 chi Graphics); Siyuan Yu (Zenustech); and Yuting Xiao, Shuai Li, Aimin Hao
 , Yang Gao, and Qinping Zhao (Beihang University)\n\nIn high-stiffness, hi
 gh-resolution simulations, while primal space methods typically fail, the 
 dual-space XPBD method produces unphysical softening artifacts due to conv
 ergence stall. We design an innovative Algebraic Multigrid method to enhan
 ce XPBD, utilizing lazy-update prolongators and near-kernel optimization. 
 Our approach ensures stability, efficiency, and scalability for high-stiff
 ness, high-resolution deformable models.\n\nInterest Area: Research & Educ
