Discrete Differential Geometry for Beginners

Discrete differential geometry bridges classical smooth mathematical theory with computational representations of surfaces and shapes. This text-based course guides you through foundational concepts, helping you understand how discrete structures preserve the essential properties of smooth geometric objects. You will build an intuitive and rigorous understanding of how polyhedral surfaces, curvature, and metric transformations function in discrete settings. By working through clear explanations and structured written exercises, you will learn how to analyze triangulated surfaces and apply modern geometric mapping techniques. What you'll learn: - Understand foundational definitions, discrete metrics, and triangulated surface representations - Explore discrete conformal equivalence and edge-length scaling principles - Compute discrete curvature and investigate discrete analogs of classical geometric invariants - Analyze discrete Laplace-Beltrami operators and conformal parameterization techniques - Apply geometric algorithms to modern computational geometry and mesh processing workflows - Solve written problem sets to evaluate surface properties and metric deformations The course begins with fundamental terminology and basic polyhedral concepts before progressing step-by-step into conformal geometry and discrete surface analysis. It is designed for students, programmers, and geometry enthusiasts seeking an approachable, rigorous introduction without requiring advanced prior coursework in differential geometry.
