Robust Topological Operations for Dynamic Explicit Surfaces
El Topo is now hosted on GitHub: [www]
El Topo is a public domain C++ package for tracking dynamic surfaces represented as triangle meshes in 3D. It robustly handles topology changes such as merging and pinching off, while adaptively maintaining a tangle-free, high-quality triangulation.
