Polygonal meshes, together with triangle meshes as their most common specialization, are ubiquitous in a wide range of computer graphics and data visualization algorithms. Without polygonal meshes, modern CGI movies, as well as 3D computer games and many kinds of visualizations of medical and other types of data are unimaginable. Representing surfaces by a set of polygons substantially simplifies work, which in most cases easily outweighs the price paid in certain loss of description precision. Another important benefit is the native support for rendering and processing in general, particularly of triangle meshes, using massively parallel graphics accelerators (GPUs).

The KIV/ZPOSE course is intended for students of computer graphics and related fields (medical informatics) or for individual students interested in the topic. The objective is to get acquainted with the properties, possibilities, advantages and disadvantages of this common data representation. We will discuss topics of appropriate representation of polygonal meshes in a computer, and then mainly of efficient processing algorithms. Students will become experience in working with polygonal meshes, which will allow them to analyze them and to solve common problems appearing in work with them. After the course, the students will perceive working with meshes as a familiar environment, where they have a good orientation and where they can use a set of non-trivial algorithmic tools that will allow them to achieve nontrivial results.
