Seminar aus Computergraphik WS 2011 Introductory Session ( ) Institute of Computer Graphics and Algorithms Vienna University of Technology Contact: Stefan Jeschke )

Stefan Jeschke 1 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 articles Summarizing and explaining (orally / written) Comparing and discussing: experience critical scientific discussion Practice to give a talk or to write a report

2 Tasks (Pre)requirements Basic knowledge in CG (“CG1” lecture) Attend 3 lectures: „Forschung und wie sie funktioniert“ (Prof. Gröller), at 5 PM in this room „Wie halte ich einen Vortrag“ (Prof. Purgathofer), at 5 PM in this room „Wie schreibt man eine wissenschaftliche Arbeit “ (Prof. Wimmer), at 10:30 AM in this room Stefan Jeschke

3 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? Stefan Jeschke

4 Procedure There will be regular meetings (about 6) with the advisor Small student groups (2-4) You explain your progress to other participants Idea: teach you scientific communication skills Language: (typically) German or in English Stefan Jeschke

5 Procedure Options for presenting your results: Final talk: 20 min + 5 min discussion English language Date: at 10 AM in this room Best talks are invited to our Konversatorium Written report 8-12 pages English language Deadline: Stefan Jeschke
