Mission statement
Learn basic scientific work flow (in CG) and improve scientific communication skills
Practice to review literature and get familiar with a particular scientific topic: reading and understanding (difficult) scientific articlesSummarizing and explaining (orally / written)Comparing and discussing: experience critical scientific discussionPractice to give a talk or to write a report

4
Procedure
Analyze some recent papers (select with advisor) Literature study relevant for paper understanding Paper results evaluation: compare with existing results / code from the web / implement it (if reasonable amount of work)
Does the algorithm work as described?How do parameters influence the result?When does the algorithm fail? (models/images/etc) How fast is the algorithm on current hardware?
