Academic Integrity (IMPORTANT)

As a course requirement, code using the skeleton provided by the course cannot and should NOT be published on GitHub.

Uploading these assignments are solely for educational and discussion purposes, as the online version of this course has stopped accepting new assignment submissions.

FOR ANYONE WHO IS CURRENTLY OR IS TO BE ENROLLED IN THIS COURSE (OR ITS ENGLISH VERSION), DO NOT VIEW OR EVEN COPY-PASTE CODE FOR ASSIGNMENTS PROVIDED INSIDE THIS COURSE REPOSITORY, AS THIS IS A DIRECT VIOLATION OF ACADEMIC INTEGRITY.

Introduction to This Course

GAMES101 (2020-02), or Introduction to Computer Graphics, conducted by Prof. Lingqi Yan, is an introductory course that explores the fundamentals of Computer Graphics. This comprehensive offering provides students with a solid foundation in essential principles and techniques used in CG, including rendering (both rasterization and modern ray-tracing), geometry, and animation. Additionally, the course showcases the captivating nature of the field and highlights cutting-edge research conducted by leading experts. Students are expected to gain a deeper understanding of visually stunning virtual environments and stay informed about the latest advancements in CG.

Appendix: List of Assignments

We list, in the following sections, features of frameworks that are expected to be implemented by students. The actual implementation may differ and can be found under the corresponding repository. (e.g., extra features)

The original framework are generally modified heavily by us to suit the need. Some of the modifications are specified in their corresponding readme.md file.

Bonus points are italicized.
