چکیده

Computational conformal geometry is an interdisciplinary field, combining modern geometry theories from pure mathematics with computational algorithms from computer science. Computational conformal geometry offers many powerful tools to handle a broad range of geometric problems in engineering fields. This work summarizes our research results in the past years. We have introduced efficient and robust algorithms for computing conformal structures of surfaces acquired from the real life, which are based on harmonic maps, holomorphic differential forms and surface Ricci flow. We have applied conformal geometric algorithms in computer graphics, computer vision, geometric modeling and medical imaging.

Computing Conformal Structures of Surfaces

According to Klein’s Erlangen program, different geometry branches study invariants of a space under different transformation groups. Topology and Euclidean geometry have been widely applied in computer graphics and vision. Between topological transformation group and Euclidean transformation group, there exists a conformal transformation group, which has not been well studied by computer scien...

Optimization of Conformal Mapping Functions used in Developing Closed-Form Solutions for Underground Structures with Conventional cross Sections

Elastic solutions applicable to single underground openings usually suffer from geometry related simplification. Most tunnel shapes possess two axes of symmetry while a wide range of geometries used in tunneling practice involve only one symmetry axis. D-shape or horse-shoe shape tunnels and others with arched roof and floor are examples of the later category (one symmetry axis). In the present...

Application of the Schwarz-Christoffel Transformation in Solving Two-Dimensional Turbulent Flows in Complex Geometries

In this paper, two-dimensional turbulent flows in different and complex geometries are simulated by using an accurate grid generation method. In order to analyze the fluid flow, numerical solution of the continuity and Navier-Stokes equations are solved using CFD techniques. Considering the complexity of the physical geometry, conformal mapping is used to generate an orthogonal grid by means of...
