Geometry Processing

Geometry Processing @ LMU Munich Winter Semester 2021/22

• Homepage: http://mimuc.de/gp
• Instructor: Changkun Ou
• Responsible Professor: Prof. Dr. Butz
• Date: Monday, 2 p.m. - 6 p.m. c.t. (starts on Oct 18, 2021)
• Location: Frauenlobstr. 7a, Raum 357

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.

Preparation

We will introduce and use the following toolkits for this course:

• Git
• Blender (2.93+)
• Node.js (14.17+)
• Python (3.7+)

Please install all of them in advance and take a glance to these tools beforehand.

Communication

We use GitHub to manage all course resources, submissions, project proposals, etc. and use the discussions feature for online questions and discussions.

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.

Students will participate in the course every week to discuss and learn more geometry processing techniques at the beginning of the semester, then do 5 out of 8 geometry processing coding projects.

During the rest of the semester, students should propose a project idea throughout the semester, and by the end of the semester, implement and demonstrate their project in 1) idea-pitch presentation; 2) intermediate presentation; 3) final presentation.

Grading

The grading scheme contains two parts: homework projects and individual project.

Homework Projects

Homework projects contribute 50% of the final grades. Select 5 out of 7 given projects (5x10%), or feel free to finish them all (no bonus, but learn more interesting algorithms).

Proportion	Topic	Deadline
10%	The Halfedge Structure	01.11.2021 23:59:59
10%	Discrete Curvature	15.11.2021 23:59:59
10%	Laplace Smooth	29.11.2021 23:59:59
10%	Tutte's Embedding	13.12.2021 23:59:59
10%	Quadric Error Metric Simplification	01.01.2022 23:59:59
10%	Rendering with PyTorch(3D)	17.01.2022 23:59:59
10%	Learning to Deform A Mesh	07.02.2022 23:59:59

Individual Project

Individual projects contributes 50% of the final grade, and separated into parts:

• (10%) Proposal document, idea-pitch presentation (1 minute)
• (10%) Intermediate representation (5 minutes)
• (10%) Video submission (<5 minutes)
• (10%) Final presentation (10 minutes)
• (10%) Code submission

The timeline for individual projects are as follows:

Note that the individual project can be conducted in parallel with the coding projects, meaning the individual projects can be submitted anytime before the deadline; Individual projects do not mean students cannot collaborate with each other. A maximum of three students can collaborate with each other to work on the same foundation of the the project, but eventually each individual project should have their uniquely implemented geometry processing algorithm or feature.
