Direct and Indirect Illumination Computation in Unreal Engine

In this bachelor thesis, I analyze Lumen, a novel lighting system introduced in Unreal Engine 5, which leverages innovative techniques to compute real-time global illumination and accurate mirror reflections. I compare Lumen to other commonly employed methods for calculating direct and indirect lighting. Furthermore, I test Lumen's performance and visual quality using various scenes created in Unreal Engine 5.5.
