HLSCM (Hierarchical LSCM)

[csparker247]

Summary

Implement a Hierarchical LSCM parameterizer as described in Lévy et al. (2002). This approach produces better parameterizations in high-curvature regions by hierarchically building and refining the parameterization.

Proposed API

// Matches the AngleBasedLSCM pattern
HLSCM<float>::Compute(mesh);

// Or with angle pre-optimization
ABFPlusPlus<float>::Compute(mesh);
HLSCM<float, ABFPlusPlus<float>::Mesh>::Compute(mesh);

Acceptance Criteria

• HLSCM<T> class with compute() and static Compute() matching AngleBasedLSCM style
• Works with the same HalfEdgeMesh types
• Tests verify correctness against known configurations
• Included in OpenABF.hpp and the amalgamated single-header
