Overview

# Tasks Skills
1. Read CG/GP articles Know about the state of the art CG/GP
2. Review a paper Assess scientific literature
3. Present a seminar Report clearly significant information

Computer Graphics / Geometry Processing

If you do a bachelor thesis with CGG:

  • You only have to attend all seminar presentations
  • You should actively participate in the discussions
  • You shall present your thesis results in a seminar

Topics

CG/GP articles have mostly been selected from papers published by top conferences

Some research areas:

  • Geometry Processing
  • Shape Analysis and Optimisation
  • Mesh Generation
  • Digital Fabrication
  • Surface Reconstruction Algorithms

How to dig an article

Identify the context:

  • Related works
  • Key ideas
  • Novelties

Some advices:

  • Watch related talks
  • Read Related Work §
  • Check out some references
  • Query Google Scholar

⚠️ Be careful to cite all the sources you’ve used 💥

Presenting is challenging

  • Time is limited
  • Attention of the audience is finite
  • Background of the audience is various

Some tips:

  1. Motivate the topic
  2. Take time to explain the fundamentals
  3. Do not overload the slides
  4. Select carefully crucial/original information
  5. Provide a take-home message

Specifications for the seminars

  • The presentation should last 20-25 minutes
  • A discussion of 10 minutes should follow
  • The presentation is given in English
  • One rehearsal (optional, but highly recommended: contact me)
