This paper presents a new precomputation pipeline for reduced deformation simulation. We use a more efficient Krylov iteration to construct linear and nonlinear modes, the random project method for mode regularization, and an even-space cubature scheme. Our method is orders-of-magnitude faster than classic modal analysis based precomputation.
