Polygonal meshes constitute a flexible and convenient representation of surfaces. This course covers geometry processing and geometric modeling based on such meshes. It complements the CAGD lecture which introduced piecewise polynomial curves and surfaces, i.e., splines.

In fact, we are now using the simplest instance of such models: piecwiese linear surfaces, i.e., triangle meshes. and show how this representation can be used to model and solve complex problems.
