Class: ClusterLightingBuffer
Defined in: src/gfx/renderJob/passRenderer/cluster/ClusterLightingBuffer.ts:13
GPU buffers backing the clustered lighting pass: the per-cluster AABB bounds, the flat light-index assignment list, the per-cluster start/count table into that list, and the uniform block describing the cluster grid. Shared by the compute pass that fills them and the fragment shaders that read them.
