- Add Google Test via CMake FetchContent (v1.14.0) - Add clausen.hpp: Clausen integral, Lobachevsky function, Im(Li2) - Add hyper_ideal_utility.hpp: generalized and ideal-vertex hyperbolic tetrahedron volume formulas using Eigen for the 4x4 Gram determinant - Port ClausenTest (5 tests) and HyperIdealUtilityTest (8 tests) from Java/JUnit — all 13 pass with same tolerances as the Java originals - Fix pre-existing VIEWER/viewer case mismatch in CMakeLists.txt Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
conformallab++
conformallab++ is a modern C++ reimplementation of the ConformalLab software by Stefan Sechelmann for experiments in discrete conformal geometry and related mesh transformations.
It builds on well‑established open‑source libraries such as CGAL, Eigen, and Boost for robust geometric data structures and efficient numerical computations, and uses single‑header libraries CLI11 and json.hpp for a lightweight command‑line interface and configuration handling. In addition, libigl’s OpenGL viewer stack based on GLFW provides portable windowing and input handling, while the separate libigl‑glad component supplies a generated OpenGL function loader for the required core profile, making interactive visualization easy to integrate.
Status
This project is in an early prototype stage.
API, file formats and command‑line interface are all subject to change.
