GoKawiilNVIDIA updates vk_lod_clusters sample, meshoptimizer gains clustered LOD improvements
NVIDIA released an updated version of its open-source vk_lod_clusters sample featuring a refreshed 1.6-billion-triangle Zorah scene rendered with path tracing and clustered raytracing. The new glTF scene data totals about 32 GB, down slightly from 36 GB last year, despite adding a full attribute set and textures, largely because processing now relies on meshoptimizer's clusterlod.h module. The author, who previously documented processing the original Zorah scene, has since contributed improvements to meshoptimizer's hierarchical clustered LOD support and is writing about the updated pipeline's other aspects beyond processing speed.
