# conformallab++
conformallab++ is a modern C++ reimplementation of the [ConformalLab](https://github.com/sechel/conformallab) software by Stefan Sechelmann for experiments in discrete conformal geometry and related mesh transformations.
conformallab++ is a modern C++ reimplementation of
[ConformalLab](https://github.com/varylab/conformallab) —
the research software for discrete conformal geometry by
**Stefan Sechelmann** (TU Berlin, Institut für Mathematik).
The algorithmic foundation is his doctoral dissertation:
> Stefan Sechelmann —
> **Variational Methods for Discrete Surface Parameterization: Applications and Implementation**
> Doctoral thesis, Technische Universität Berlin, 2016.
> DOI: [10.14279/depositonce-5415](https://depositonce.tu-berlin.de/items/8e2988b2-d991-45b5-aad5-9fb7988f3b2f)

The dissertation develops the variational framework for discrete conformal equivalence
on triangulations — discrete uniformization of Riemann surfaces, cone metrics, period
matrices — that forms the mathematical core of both the Java original and this C++ port.
**Original Java library:** [github.com/varylab/conformallab](https://github.com/varylab/conformallab) (Java, ~850 commits, v1.0.0 2018)

The long-term goal is a **CGAL package** that brings discrete conformal maps (hyper-ideal, spherical, Euclidean) to the CGAL ecosystem using `CGAL::Surface_mesh` as the underlying half-edge data structure.

## Ursprung & Danksagung
conformallab++ wäre ohne die Grundlagenarbeit von **Stefan Sechelmann** nicht möglich.
Die Algorithmen, die Variationsformulierung und die Idee, diskrete konforme Geometrie
als Newton-Problem auf Winkel-Summen-Energie-Funktionalen zu behandeln, stammen aus:
