News

  • 01.03.2021:Geometry processing will return in WS21/22.
  • 12.02.2021:We will have an invited guest talk from WAY Digital Solutions GmbH that talks about 3D modeling industrial and practices on 22.02.2021, it is a great opportunity to get in touch, please reserve your schedule beforehand if you are interested.
  • 24.01.2021:The Deformation session is merged into the Data-driven method session. They will be discussed together at 08.02.2021.
  • 12.01.2021:Exam registration is open at Uni2Work.
  • 05.11.2020:We updated the module information for further clarification with respect to the study regulations. Now, this course can also be recognized as a Praktikum (P5) for (Medien-)Informatik master students.
  • 02.11.2020:We just finished the first introduction session, there is a homework document, please check it on our GitHub repository.
  • 31.07.2020:Registration for Bachelor and Master students is open in Uni2Work.
  • 31.07.2020:We now have a brand new computer graphics related course ✨.

Prerequisites

The course is designed for senior bachelor students or master students who have taken those following courses (or have equivalent knowledge):

  • Computer Graphics 1

Registration is open at Uni2Work both for Bachelor students and Master students.

Communication

We use our GP GitHub repository to manage all course resources, submissions, project proposals, etc. and use its issue tracker for online questions and discussions.

Please register yourself on GitHub if you do not have a GitHub account yet. You can use any distinguishable identifier for your username if you do not want your real name to appear on GitHub publicly.

Preparation

Since we use GitHub to organize the course, it is recommended for you to get familiar with GitHub beforehand. The following lists tools are used in the course, please install them before you taking the course: Blender (2.90+), Node.js (v14+).

Additional tools may also be introduced during the course. For more information, please check the GitHub repository.

Syllabus

In this practical course, students will learn and practice more about geometry processing algorithms in 3D graphics, including mesh representation, discrete differential geometry, smoothing, parameterization, remeshing, deformation, shape analysis, etc.

During the semester, students will participate in the course every two weeks to discuss and learn more geometry processing techniques, then do 5 out of 6 geometry processing coding projects.

Along the semester, students should propose a project idea, and by the end of semester, implement and demonstrate their project in 2 minutes using a pre-recorded video.

  • Date: Monday, 2 p.m. - 6 p.m. (starts on Nov 2, 2020)
  • Location: Zoom (Password was sent via Uni2Work Email)

Disclaimer

While LMU is closed, most teaching happens currently online. As teachers, we ask you to be forgiving if things should not work perfectly right away, and we hope for your constructive participation. In this situation, we would also like to explicitly point out some rules, which would be self-evident in real life:
  • In live meetings, we ask you to responsibly deal with audio (off by default) and bandwidth (video as needed).
  • Recording or redirecting streams by participants is not allowed.
  • Distributing content (video, audio, images, PDFs, etc.) in other channels than those foreseen by the author is not allowed.
If you violate one of these rules, you can expect to be expelled from the respective course, and we reserve the right for further action. With all others, we are looking forward to the joint experiment of an "online semester".
