Computational geometry studies algorithms for geometric problems. In Computer Science, we are interested primarily and discrete and combinatorial geometry (as opposed to continuous geometry). Typically, computational geometry algorithms involve finite sets of points, line segments or polygons. For example, we might be given the location of post-offices on a map, and want to find the closest pair of post-offices; Or we might want to find a triangulation of a set of surface samples that maximizes the minimum angle of a triangle ---- this type of meshing is often used in solid modeling, where small angles cause numerical instability; or, we might be given two sets of segments, and want to find their intersections. These are some simple examples of geometric problems. There are many fields in Computer Science that encounter geometric problems, such as computer graphics, computer vision and image processing, robotics, and GIS. This class will cover the core computational geometry topics: convex hulls, line segment intersection, guarding and art gallery, segment intersection, point location, Voronoi diagrams, Delaunay triangulations, and geometric data structures.

Office hours: Wed 1-4pm. For quick questions, you can drop by any time you see the door open. Or, send me an email to setup a (different) time; I'll do my best to accomodate you, but keep in mind my schedule can get pretty full.
Class mailing list: csci3250 at bowdoin.edu. Use it to ask questions. Since somebody else in the class might have the same question, using a mailing list is better for everyone than emailing me.
