Abstract:
We present tools for generating planar embeddings of triangulated topological spheres using a representation based on Schnyder labelings. These linear algorithms use only integers, enabling exact computations. The fast conversion between representations enables efficient fixing of flipped triangles in planar triangulations and is significantly faster than existing robust approaches.
