Students acquire a systematic understanding of algorithmic problems and solution approaches in the area of computational geometry, which builds upon their existing knowledge of theoretical computer science and algorithmics. After successful participation in this course students shall be able to
- explain concepts, structures and problem definitions that were presented in class
- execute algorithms on example instances, analyze them precisely and prove their properties
- select which algorithms and data structures are suitable for solving a given geometric problem and adapt them appropriately
- analyze new geometric problems, reduce them to their algorithmic core, and design appropriate abstract models; based on the concepts and techniques presented in class, they can subsequently design and analyze their own algorithms in these models.
Spatial data are processed in various subfields of computer science, e.g. in computer graphics, visualization, geographic information systems, robotics etc. The area of computational geometry deals with the design and analysis of geometric algorithms and data structures. In this module we present common techniques and concepts in computational geometry in the context of selected and applied geometric questions. The following topics are covered in the course:
- convex hulls
- line segment intersections
- polygon triangulation
- range queries
- point location
- Voronoi diagrams and Delaunay triangulations
- duality of points and lines
- quadtrees
- well-separated pair decomposition
