I wonder if this is the “RTX Mega Geometry” they showed to the Digital Foundry guys a few weeks back: https://youtu.be/HLxVskv2zs0?si=V1wi_4xCgk5M34gL https://y

  It's related to that, RTX Mega Geometry refers to a new (currently Nvidia-only) set of driver APIs which enable Nanite-like geometry streaming for raytracing acceleration structures. This library could be used to generate the data to feed those APIs. There's a link to another repo demonstrating how to render this data using either rasterization via mesh shaders, or raytracing via their Mega Geometry extension. https://github.com/nvpro-samples/vk_lod_clusters https://github.com/nvpro-samples/vk_lod_clusters I expect something along the lines of Mega Geometry will be standardized in DirectX and Vulkan eventually, but that takes time.
