Illustration of iterative linear solver behavior on simple 1D and 2D problems
Nicolas Ray, Sokolov Dmitry
In geometry processing, numerical optimization methods often involve solving sparse linear systems of equations. These linear systems have a structure that strongly resembles to ad…

Inappropriate use of L-BFGS, Illustrated on frame field design
Nicolas Ray, Dmitry Sokolov
L-BFGS is a hill climbing method that is guarantied to converge only for convex problems. In computer graphics, it is often used as a black box solver for a more general class of n…

On Smooth 3D Frame Field Design
Nicolas Ray, Dmitry Sokolov
We analyze actual methods that generate smooth frame fields both in 2D and in 3D. We formalize the 2D problem by representing frames as functions (as it was done in 3D), and show t…
