Technical analysis of hardware ray tracing in GTA 6: Ray-Traced Global Illumination (RTGI), Surfel Radiance Caching, and vehicle clear coats.
Welcome to the GTA 6 Ray Tracing & Lighting Architecture Hub. This section is dedicated to breaking down Rockstar's move from legacy pre-baked cube maps to real-time hardware-accelerated ray tracing.
In coastal Vice City, ray tracing touches virtually every surface. We investigate how Ray-Traced Global Illumination (RTGI) calculates indirect multi-bounce radiosity through neon-soaked nightlife, how Bounding Volume Hierarchy (BVH) acceleration trees manage millions of foliage polygons in the Everglades, and how physical water surfaces refract and reflect light using dynamic caustic shaders.
A beginner-friendly guide to ray tracing in GTA 6: how light bouncing, car mirror reflections, and soft shadows bring Vice City to life.
How RAGE 9 models tropical storms, Rayleigh scattering, volumetric fog voxel grids, and day-night lighting cycles in Grand Theft Auto VI.
