Overview

This course provides the theoretical and practical foundations for computer graphics. It gives a wide overview of topics, techniques, and approaches used in various aspects of computer graphics with a focus on image synthesis and rendering, including texturing, shading, aliasing, sampling, and many more.

After introducing the two basic algorithms for image synthesis, ray tracing and rasterization, it discusses the physical foundations of ray tracing in greater depth. As part of the practical exercises, the students incrementally build their own ray tracing system, which they will then use to generate a high-quality rendering for the end-of-term rendering competition.

Additionally, on the discretion of the course organizers, an additional BVH speed competition may be held for bonus points.

Language

All lectures and course materials are given in English

Tutoring sessions are also given in English, altough some tutors may be able to help you in another language at their own discretion.

Pre-requisites

  • Programming experience with C++
  • Basic knowledge of linear algebra and analysis

Organisation

The course (lectures & tutorials) will be organized using Microsoft Teams.

We decided to not make use of the mailing list this year, instead announcements will be done using Teams as well.

In-person lectures are something we wish to make happen this year, but cannot commit to provide yet. It is likely a hybrid model will be deployed, with the lecture being broadcast from a lecture hall for students unable to attend. In all cases the lecture should be accessible for remote students.

Tutorials

Each student is assigned a tutor which will be responsible for them during the course. Each tutor hosts a weekly one-hour session answering questions about the next assignments and providing insight into the previous one.

Schedule TBD !

Location: Online, Microsoft Teams

Assignments

This course contains a practical commponent int he form assignments. The assignments are mandatory for passing the course. You may group up with another student for solving the assingments. The assignments will be posted under the course schedule. They include a mix of theoretical and programming exercises.

The paper copies for the theoretical parts of the assignments will be collected at the beginning of the lecture on the due date. The programming parts must instead be sent by email to your respective tutors. You can also send the scans of your paper copy by mail to your tutor if your are unable to attend the lecture.

The code submitted for the programming part of the assignments is required to reproduce the provided reference images, and the submission ought to include the mandatory generated images. The submission should also contain a creative image show-casing all extra-credit features that have been implemented.

The projects are expected to compile and work out of the box on the machines in the CIP-pool students’ lab in order to give the tutors a guarantee that the code will run on machines that both them and the students have access to.

Exams

A sample for the final exam is provided here.

Rendering Competition

The Rendering Competition is a final showcase of how the ray tracing engine that was developed throughout the course can be used to render interesting images.

Zoom

We would be happy if we could create a pleasant lecture environment despite the current situation. Personal interactions, with your microphone and camera switched on, may contribute to this environment. We also encourage you to ask questions verbally. Note that this is voluntary. You may switch off both your camera and your microphone, and register under a pseudonym. Questions are still possible, in particular using the chat function.

We have decided to use Zoom as a videoconferencing service. Note that this provider (Zoom Video Communications, Inc., 55 Almaden Blvd, Suite 600, San Jose, CA 95113, USA) can access all data that you provide when registering for the video conference. If you do not provide personal data during the registration, there is still a possibility that Zoom identifies you using your IP address. We would not have decided to use Zoom if we considered this as a significant risk. As an additional precaution, we have opted to use European computing centers. Should you still have privacy concerns (and are not using an Internet Service Provider that cannot map IP addresses to your name), we suggest using an anonymization service such as Tor (https://www.torproject.org/)
