Cyril Crassin ![](/sites/default/files/person/Moi_2019_05_004_small.jpg) Cyril Crassin joined NVIDIA Research in 2011. His research interests include real-time and realistic rendering, alternative geometric and material representations (especially voxel-based), anti-aliasing techniques, global illumination, real-time ray-tracing and out-of-core data management. Prior to joining NVIDIA, Cyril obtained his Ph.D. degree from Grenoble University at INRIA in France. His most impactful contributions are the GIVoxels/VXGI voxel-based indirect illumination technique, with several hardware implications in the NVIDIA Maxwell architecture, as well as the GigaVoxels rendering pipeline that proposed the use of pre-filtered voxel representations for efficient real-time rendering of very large and detailed scenes and complex objects.
