Detailed Description

Configuration for the ClusterSAH direct PackedBVH construction path.

ClusterSAH first groups primitives into small, spatially-tight clusters (buckets of at most maxClusterSize primitives, formed by a cheap density-adaptive midpoint subdivision that stops early), then runs binned SAH top-down over the clusters – so SAH partitions ~N/maxClusterSize boxes instead of all N primitives. The result is a near-SAH-quality tree at a fraction of the single-threaded build cost, robust across uniform, surface, and clustered primitive distributions (unlike a fixed Cartesian grid, which overcrowds on non-uniform data). maxClusterSize trades build time (larger -> fewer, cheaper SAH units, faster build) against query quality (larger -> coarser leaves).
