Abstract Ricci flow deforms the Riemannian metric proportionally to the
curvature, such that the curvature evolves according to a heat diffusion process
and eventually becomes constant everywhere. Ricci flow has demonstrated its
great potential by solving various problems in many fields, which can be hardly
handled by alternative methods so far.



This work introduces the unified theoretic framework for discrete Surface
Ricci Flow, including all the common schemes: Tangential Circle Packing,
Thurston’s Circle Packing, Inversive Distance Circle Packing and Discrete
Yamabe Flow. Furthermore, this work also introduces a novel schemes, Virtual
Radius Circle Packing and the Mixed Type schemes, under the unified
framework. This work gives explicit geometric interpretation to the discrete
Ricci energies for all the schemes with all back ground geometries, and the
corresponding Hessian matrices.



The unified frame work deepens our understanding to the the discrete surface
Ricci flow theory, and has inspired us to discover the new schemes, improved
the flexibility and robustness of the algorithms, greatly simplified the
implementation and improved the efficiency.
