Surface reconstruction from point cloud using a semi-Lagrangian scheme with local interpolator
Silvia Preda, Matteo Semplice
We propose a level set method to reconstruct unknown surfaces from point clouds, without assuming that the connections between points are known. We consider a variational formulati…

A CWENO large time-step scheme for Hamilton--Jacobi equations
E. Carlini, R. Ferretti, S. Preda +1
We propose a high order numerical scheme for time-dependent first order Hamilton--Jacobi--Bellman equations. In particular we propose to combine a semi-Lagrangian scheme with a Cen…
