Exam

• written for students from
  • Bachelor Informatik
  • Bachelor Medieninformatik
  • CMS students
  • exchange students (register by email to Benjamin Russig)
• oral exam onsite for Master and Diploma students (arrange appointment by email to Jana Bohl).

A list of sample questions for oral exams can be found here: questionaire
Formulas and algorithms from the lecture which you should have a throurough unterstanding of for written exams are compiled here: formulas/algorithms
Example exam from WS19/20: pdf

Joint consultation with Prof. Gumhold: t.b.a

Some specifics about the written exam:

• The exam covers material from the following four areas
  • polygonal meshes including lectures on polygonal meshes, halfedge data structure and mesh processing
  • surface analysis
  • rendering with lectures on OpenGL, geometry rendering, lighting and texturing
  • acceleration datastructures
• Each of the four areas will be scored about equally.
• The questions, based on the oral questionaire, will query generic, algorithmic and programming knowledge, as well as some analytic calculations. Required formulas will be provided in the task descriptions. Note that the exam questions will NOT be sampled from this questionaire! It is supposed to give you an idea what knowledge might be subject to questions, it is not meant for you to commit all answers to these questions to memory before the exam! The questions will be comparable, but not the same.

Sample Code

• cg1-samples@bitbucket (sample models: zip)
• EarthDemo (zipWS16 including data)
• Realtime rendering C++-OpenGL-Code samples of Nico Schertler GitHub (3D models: zip)
• Nehe Tutorials

Excercises

Exercises will run as usual during the sabbatical of Prof. Gumhold.
