Progressively Projected Newton's Method
José Antonio Fernández-Fernández, Fabian Löschner, Jan Bender
Newton's Method is widely used to find the solution of complex non-linear simulation problems in Computer Graphics. To guarantee a descent direction, it is common practice to clamp…
Pitfalls of Projection: A study of Newton-type solvers for incremental potentials
Andreas Longva, Fabian Löschner, José Antonio Fernández-Fernández +3
Nonlinear systems arising from time integrators like Backward Euler can sometimes be reformulated as optimization problems, known as incremental potentials. We show through a compr…
SymX: Energy-based Simulation from Symbolic Expressions
José Antonio Fernández-Fernández, Fabian Löschner, Lukas Westhofen +2
Optimization time integrators are effective at solving complex multi-physics problems including deformable solids with non-linear material models, contact with friction, strain lim…
