Great Siggraph 2025. Tons of good talks. #AssassinsCreedShadows of course :), Gran Turismo 7, Activision, Neural Shading and Workgraph courses. Great stuff. And a lot of content is already online. It’s great to see so much sharing. #SIGGRAPH2025
Great Siggraph 2025 presentation of Gran Turismo's tonemapping pipeline, which also includes a fantastic introduction to light perception and tonemapping, its origins and how it evolved over the years with display technology, recommended read: blog.selfshadow.com/publications...
