The penetr ation-free guarantee is inspired by the interior point method, which conve rts the inequality constraints to barrier potentials. We propose a major o verhaul of this modality within the projective dynamics framework by lever aging an adaptive weighting mechanism inspired by barrier formulation. Thi s approach does not depend on the distance between mesh primitives, but on the virtual life span of a collision event and thus keeps all the vertice s within feasible region. Such a non-distance barrier model allows a new w ay to integrate collision resolution into the simulation pipeline. Another contributor to the performance boost comes from the subspace reuse strate gy. This is based on the observation that low-frequency strain propagation is near orthogonal to the deformation induced by collisions or self-colli sions, often of high frequency. Subspace reuse then takes care of low-freq uency residuals, while high-frequency residuals can also be effectively sm oothed by GPU-based iterative solvers. We show that our method outperforms existing fast cloth simulators by at least one order while producing high -quality animations of high-resolution models.\n\nRegistration Category: F ull Access, Full Access Supporter\n\nLanguage Format: English Language\n\n Session Chair: Paul Kry (McGill University) URL:https://asia.siggraph.org/2024/program/?id=papers_155&sess=sess126 END:VEVENT END:VCALENDAR
