Tarik Moussa	516ac89bd8	feat(phase3b): port HyperIdealFunctional energy + gradient onto ConformalMesh ... Implements the hyper-ideal discrete conformal map functional on CGAL::Surface_mesh. The energy and analytic gradient are ported directly from HyperIdealFunctional.java; correctness is verified via a finite-difference gradient check (same eps=1E-5 / tol=1E-4 as Java). New files: include/hyper_ideal_geometry.hpp — ζ, ζ₁₃, ζ₁₄, ζ₁₅, lij, αij, σi, σij include/hyper_ideal_functional.hpp — HyperIdealMaps, evaluate_hyper_ideal, gradient_check tests/cgal/test_hyper_ideal_functional.cpp — 6 tests (1 skipped @Ignore) Test results (local, -DWITH_CGAL=ON): conformallab_cgal_tests: 21 registered | 20 passed | 1 skipped | 0 failed - GradientCheck_AllHyperIdealTriangle ✓ - GradientCheck_ExtendedDomain ✓ - GradientCheck_TetrahedronAllVariable ✓ - EnergyFiniteAtTestPoint ✓ - GradientCheck_MixedIdealHyperIdeal ✓ - GradientCheck_Fan6AllVariable ✓ Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-11 23:10:23 +02:00
Tarik Moussa	bf9c323d60	feat(phase3a): introduce CGAL Surface_mesh as ConformalMesh foundation ... Replaces the Java CoHDS with CGAL::Surface_mesh<Point3> (Simple_cartesian kernel). Adds domain-specific property maps for lambda/theta/idx/alpha and face geometry type — the direct C++ equivalent of CoVertex/CoEdge adapters. New files: include/conformal_mesh.hpp — ConformalMesh type + property-map helpers include/mesh_builder.hpp — mesh factories (triangle, tetrahedron, quad-strip, fan) for tests and examples tests/cgal/ — second test executable (conformallab_cgal_tests) built only with -DWITH_CGAL=ON Test results (local, -DWITH_CGAL=ON): conformallab_tests: 36 registered | 23 passed | 13 skipped | 0 failed conformallab_cgal_tests: 14 registered | 14 passed | 0 skipped | 0 failed Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-11 18:36:21 +02:00
