Lightfuker is a ray tracer built on the Lightwave framework. This project was developed by me and Tien Nhat Minh Nguyen for the Computer Graphics Winter 2025/26 rendering competition at Saarland University. Check out the project branch for the code.

Lightwave was written by Alexander Rath, with contributions from Ömercan Yazici and Philippe Weier. Many of our design decisions were heavily inspired by Nori, a great educational renderer developed by Wenzel Jakob. We would also like to thank the teams behind our dependencies: ctpl, miniz, stb, tinyexr, tinyformat, pcg32, and catch2.
