Computer Graphics 1

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.

Assignments

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 guaranty that the code will run on machines that both them and the students have access to.
