- Add const-correctness to function parameters throughout the algorithm - Remove redundant EdgePairEqual struct (std::pair already has operator==) - Change fastChainLinkSort windingDict to std::map for cross-platform determinism - Remove unused Triangulation members (m_Mesh, m_SubTri, m_EdgeList) and accessors - Use dense Eigen matrices for vertex data instead of sparse (2.7x perf improvement) - Add throttled messaging and cancel checks in processing loop - Use std::move for Eigen matrix transfer to avoid copies - Switch boundary dict to OrderedEdgeDict (std::map) for reproducible results - Update test to use exemplar-based comparison with correct error threshold Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
