Detailed Description

Per-cluster LOD data for GPU-driven LOD selection.

Each cluster maps to one meshlet. A cluster renders when its parent group still exceeds the configured error threshold and its refined group is already below that threshold, or when refinedGroupId is -1 for base geometry. Layout matches GLSL std430 ClusterLodData and is 48 bytes.
