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 ...
- Knowledge of advanced and more complex methods and techniques of computer graphics.
- Mastering of some of the topics that were already touched upon in the basic computer graphics course, by expanding them in greater depth.
- Ability to follow the current research literature on those topics.
- Skills to implement complex techniques in those areas.
- Knowledge of the principles of photorealistic image generation.
- Larger overview over the amazing wealth of topics and research questions in computer graphics,
There are no formal prerequisites, but some degree of the following skills are desirable:
- A little bit of experience with C/C++ ; note that you will need just "C with classes" during this course.
- 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).
- Algorithmic thinking (and, hopefully, some pleasure when thinking about algorithms)
Some of the envisioned topics (these can change during the semester):
- Data structures and the theory of boundary representations (meshes);
- Advanced methods for texturing (more realistic ;
- Generalized barycentric coordinates and parameterization of meshes;
- Advanced shader programming (special effects);
- Culling techniques (real-time rendering);
- Ray-tracing (photo-realistic images);
- Alternative object representations (modeling);
- Anti-aliasing (improvement of quality)
FolienThe following table contains the topics and the accompanying slides (it will be filled step-by-step).
Ray-tracing 1: principle, camera models, lighting model, secondary rays, refraction, Fresnel terms, attenuation, dispersion, intersection ray-polygon, intersection ray-triangle,
ray-tracing height fields,
numerical robustness, distribution ray-tracing,
stratified and Poisson disk sampling,
anti-aliasing, soft shadows, glossy-matte reflection,
Object representations: quadrics and superquadrics, implicit surfaces, root finding with Laguerre's method,
You can download some of the shaders that were discussed in class, plus some some very simple ones (discussed in the Bachelor course).
The following textbooks can help review the material covered in class:
- Andrew Glassner (ed.): An Introduction to Ray Tracing; Morgan Kaufman
- Peter Shirley: Realistic Ray Tracing; AK Peters.
- Foley, van Dam, Feiner, Hughes: Computer Graphics -- Principles and Practice; Addison Wesley.
- Tomas Akenine-Möller, Eric Haines: Real-Time Rendering; AK Peters.
- Matt Pharr, Wenzel Jakob, Greg Humphreys: Physically-Based Rendering; Morgan Kaufmann. (Commonly referred to as PBRT)
- Alan Watt, Mark Watt: Advanced Animation and Rendering Techniques. Addison-Wesley
- Online Literature, see below
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.

- A nice tutorial on the DCEL data structure by Ryan Holmes (source)
- A tutorial on specification, representation, and construction of non-manifold geometric structures (this is only partially relevant for our course, but it can serve as an outlook on how to extend the concepts into n-dimensional geometry)
- Two essays on the Euler characteristic: one by Edward Early (source), and one by Sudesh Kalyanswamy (source), the latter being more geared towards graphs, but still relevant in computer graphics, too.
- A simple proof of the Jordan Curve Theorem for the important class of polygons (source)
- Similar to regular polyhedra, one can even define Infinite Regular Polyhedra, and, here too, the genus plays a very important characterizing role (source)

Other Interesting Bits and Pieces
- Not exactly about computer graphics, but here is a clip from an interview with Linus Torvalds, where he speaks about tasteful code. And although he does not explicitely mention it, I strongly believe that tasteful code is what makes robust code. (Source: Linus Torvalds: The mind behind Linux, February 2016 at TED2016.)
