We introduce a new integral formulation of this problem, which assigns confidence\r\nscores that points are inside or outside, given incomplete boundary geometry. Even though our geometric construction does\r\nnot appear in previous work, we show that it is unexpectedly linked to both the well-established generalized winding number\r\n(GWN) and pseudonormal methods for geometry completion, and it provably reduces to either one of them for specific values\r\nof a control parameter. The results obtained with our method frequently outperform screened Poisson surface reconstruction\r\n(PSR), GWN, and the pseudonormal method in terms of quality, and are at least on par with them on all of our examples. Unlike\r\nthese methods, our algorithm naturally extends to the multi-label setting, in which regions with an arbitrary number of colors\r\nor physical materials can be reconstructed, and non-manifold features such as T-junctions may appear in the interface and\r\nboundary geometry"}],"publication":"Computer Graphics Forum","date_created":"2026-06-23T09:08:41Z","file_date_updated":"2026-06-23T09:07:22Z","date_updated":"2026-06-24T05:49:08Z","type":"conference","month":"06","corr_author":"1","doi":"10.1111/cgf.70516","day":"24","publication_status":"accepted","department":[{"_id":"ChWo"},{"_id":"GradSch"}],"quality_controlled":"1","language":[{"iso":"eng"}],"oa_version":"Published Version","status":"public","citation":{"mla":"Wei, Ziyu, et al. “Circles of Confidence for Multi-Label Geometry Completion.” <i>Computer Graphics Forum</i>, vol. 45, no. 5, Wiley, doi:<a href=\"https://doi.org/10.1111/cgf.70516\">10.1111/cgf.70516</a>.","chicago":"Wei, Ziyu , Christian Hafner, Aleksei Kalinov, Peter Synak, and Chris Wojtan. “Circles of Confidence for Multi-Label Geometry Completion.” In <i>Computer Graphics Forum</i>, Vol. 45.
