Instances of this prototypical problem\r\nshow up in computing direction fields and stripe patterns, quadrilateral\r\nmeshing, and visualization of fluid flows. When the class of allowed fields\r\nincludes those with topological defects, a relaxation is required to make\r\nthe problem well-posed. We observe that these problems can be viewed\r\nas synchronization problems, which admit a natural semidefinite relaxation.\r\nWe propose a unified method of solving all these problems via the efficient\r\nBurer-Monteiro factorization method. Geometrically, this amounts to lifting the field values to a higher-dimensional manifold, naturally resolving\r\nthe singular nature of defects. Practically, we show that our convex relaxation method achieves better and more reliable optima than previous work\r\nemploying alternative relaxations","lang":"eng"}],"title":"Synchronizing fields with singularities","corr_author":"1","ddc":["000"],"month":"06","publication":"SIGGRAPH Conference Papers","date_created":"2026-05-29T12:53:59Z","oa":1}]
