  v0.2.0 — Java-port complete (Phase 1–7)

  user2595 released this 2026-05-14 11:22:20 +00:00

  Discrete conformal geometry library, C++ reimplementation of
  Stefan Sechelmann's ConformalLab (TU Berlin, 2016).

  Highlights
  ──────────
  • Three geometry modes: Euclidean (ℝ²), Spherical (S²), Hyper-ideal (H²)
  • Newton solver with SimplicialLDLT + SparseQR fallback for gauge modes
  • Priority-BFS layout (ℝ² / S² / Poincaré disk) with seam-aware halfedge_uv
  • Möbius holonomy tracking (SU(1,1)) for hyperbolic surfaces
  • Period matrix τ ∈ ℍ with SL(2,ℤ) reduction (genus 1)
  • Fundamental domain parallelogram + tiling
  • Gauss–Bonnet check/enforce, tree-cotree cut graph
  • Full serialisation (JSON / XML / OFF) + CLI app
  • 194 tests (158 CGAL + 36 non-CGAL), 2 intentional skips

  Next: Phase 8 — CGAL package structure
