Advanced Computer Graphics - SS 2017

This course will introduce students to advanced and more complex methods and techniques of computer graphics. Some of the topics that were touched upon in the Bachelor course "Computer Graphics" will be covered in more depth. In addition, more and other topics will be covered that were not taught in the Bachelor's course. This apporach will both broaden and deepen students knowledge about the field of computer graphics.

This course is for you, if you want to acquire ...

There are no formal prerequisites, but some degree of the following skills are desirable:

  1. A little bit of experience with C/C++ ; note that you will need just "C with classes" during this course.
  2. Knowledge of the material of the Bachelor course "Computer Graphics" (if you didn't manage to attend that course, you can easily recap that material for yourself).
  3. Algorithmic thinking (and, hopefully, some pleasure when thinking about algorithms)

Some of the envisioned topics (these can change during the semester):

  1. Data structures and the theory of boundary representations (meshes);
  2. Advanced methods for texturing (more realistic ;
  3. Generalized barycentric coordinates and parameterization of meshes;
  4. Advanced shader programming (special effects);
  5. Culling techniques (real-time rendering);
  6. Ray-tracing (photo-realistic images);
  7. Alternative object representations (modeling);
  8. Anti-aliasing (improvement of quality)

Note: first lecture is on April 12!

You can download some of the shaders that were discussed in class, plus some some very simple ones (discussed in the Bachelor course).

Textbooks

The following textbooks can help review the material covered in class:

Please note that the course is not based on one single textbook! Some topics might even not be covered in any current textbook! So, I'd suggest you first look at the books in the library before purchasing a copy.

If you plan on buying one of these books, you might want to consider buying a used copy -- they can often be purchased for a fraction of the price of a new one. Two good internet used book shops are Abebooks and BookButler.
