Abstract

This thesis explores the application of ray tracing algorithms in creating photorealistic scenes and their integration into virtual reality (VR) environments. Ray tracing, an advanced rendering technique, simulates the behavior of light rays as they travel through a scene, resulting in realistic effects such as reflections, shadows, and refractions. The practical part focuses on implementing key elements of ray tracing, specifically the calculation of ray-object intersections, performance optimization, and integration with global illumination in Unity. The study demonstrates how ray tracing can enhance the visual fidelity of VR, but also highlights the technical challenges, particularly in maintaining performance in real-time applications. Through a case study, the key benefits and limitations of ray tracing in VR are examined, providing valuable insights into its potential to improve image quality and user experience.
